After rescuing Chizu, Hibiki spends the night at the memorial where Asumu is staying. The next day, Asumu meets Hibiki out by the beach and they discuss what Hibiki does for a living. As Hibiki searches the mountain, Asumu follows him and is attacked in the woods, where he is rescued and witnesses Hibiki transform to fight the Hime and her child, a demon-spider called Tsuchigumo.

Both Adachi and Hibiki return to Tokyo where Hibiki is sent off to defeat a Yamabiko sighted at Okutama. Later on, Hibiki meets Asumu�s mother, who is ecstatic to see him. Meanwhile, the strain of studying for entrance exams begins to trouble Asumu as he worries about Hibiki and how safe he is with the type of job he has.

Asumu trails an old man whom he believes has connections to Hibiki after he sees him save a young girl. Elsewhere, Hibiki continues his battle with the Makamou who had been killing people in the forest. After the battle, Hibiki and Kasumi return to Tachibana�s sweet shop, where the Asumu and the old man are.

After a discussion with Hibiki about his plans after middle school, Asumu is reminded that he has no choice but to pass his entrance exam into Jounan, and he resolves to not see Hibiki until he gets in so he can share the good news. Meanwhile, Hibiki heads out after news that one of his comrades was injured in a fight, but can he handle an unfamiliar type of Makamou?

Ibuki, thinking Asumu is Hibiki�s apprentice, takes Asumu to where Hibiki and Kasumi are located. Hibiki and Asumu have a discussion about life and the challenges that everyone faces, leaving Asumu with a renewed passion to do well on his entrance exams. Hibiki then returns to battle the Bakegani that defeated him previously.

Excited over passing his entrance exam for Jounan, Asumu rushes to tell Hibiki the good news but is told he is training at a shrine deep in the mountains. Hinaka tells him how to get there and he sets off by himself. Meanwhile, Ibuki�s apprentice Akira arrives in the mountains and is attacked, forcing Ibuki to transform to fight a flying Makamou.

Lost in the forest, Asumu stumbles onto Ibuki�s camp where an irritated Akira tells Asumu that he will only hinder Hibiki if he continues following him around and that it would be best for him to leave. Asumu wonders just how true her words are and asks Hibiki himself how he feels about it after he arrives at the camp. Ibuki then defeats the Ittan-momen and Akira and Asumu make amends with each other.

Spring break has started and Asumu has already gotten off on the wrong foot, having missed going to the movies with his friend. He spends the rest of the day wandering around town and eventually encountering shoplifters. Meanwhile, Hibiki looks to see if his training paid off by taking down an Ooari while Ibuki and Akira track down a Makamou that seems to be a little more than they had suspected.

Asumu continues to wander through town after being a witness to the shoplifting, not really sure of himself and what to do next. Meanwhile, Hibiki and Ibuki team up to take down a very rare Makamou, Otoroshi.

A new school year has started and Asumu enters high school but still has mixed feelings on the path of life he has taken. Through all the aimless wandering he finds himself back at Tachibana�s Sweet Shop, but Hibiki has traveled out to the countryside after a call about people strangely disappearing where he faces off with new armored versions of the Douji and Hime.

After going through a false wall in Tachibana�s Sweet Shop, Asumu stumbles upon the Oni R&D room where Midori shines some light on Hibiki�s past.

Asumu returns home after spending a week hospitalized and begins his recuperation. Elsewhere, Zanki reveals that he will soon be retiring and expects his apprentice Todoyama to take his place, a revelation that Todoyama is less than pleased with. Even more, they are called to aid Sabaki at Tsukama Village, where a Yamaarashi is running rampant.

Zanki and Todoyama come to Sabaki�s rescue after being captured by the Yamaarashi, but Zanki begins to weaken and proves unable to defeat it. Todoyama takes Zanki�s place and destroys his first giant-type Makamou.

Kasumi and Ibuki go clothes-shopping on their day off. After shopping and during their meal, Ibuki sees a Douji and Hime pair in the city and begins his pursuit. Elsewhere, Hitomi is having mixed feelings about Asumu and Akira spending so much time together. After defeating the Douji/Hime pair, Ibuki is attacked by a Makamou that eats his disk animals as he waits for Akira to arrive with his Reppu!

Akira makes her way towards the ever-changing location of the Oonamazu but as she heads towards the battle, a puppet-type Makamou causes her to collapse under a bridge.

Finally, having tracked down the Oonamazu, Ibuki proceeds underground into the sewers to fight it for the final time�

Asumu begins his first day at Tachibana�s and discovers that Todoroki and Hitomi are related.

Meanwhile, Hibiki practices on a dirtbike while waiting on standby�

Zanki visits Todoroki on the battlefield to question about his style of fighting while Asumu begins to have troubles at Tachibana�s and is then pulled into a conversation with Ichiro about the Oni. Hibiki later joins Todoroki in a fight against an Amikiri as Zanki makes a decision about his and Todoroki�s future.

While Hibiki enjoys a day off of fighting to run errands with Asumu, Ibuki and Todoroki are separately following two groups of Makamou that are heading towards Mount Asama. The Oni find it strange that the Makamou don�t want to fight nor do they attack humans, so just what is at the top of the mountain that draws them?

As Asumu and Mochi wait for Hibiki to return with the doctor, Akira is injured as Ibuki and Todoroki combine their strength to defeat the pair of Douji and Hime, but the Ubume and Yamaarashi are nowhere to be found. What they do find is a new, disturbing hybrid of the two Makamou and despite their best efforts, they can�t defeat it alone. Just then, Hibiki arrives as backup�

Hibiki takes Todoroki to his mountain training temple to teach him how to play the taiko so that the Oni are better prepared to deal with the summer Makamou, which are resistant to stringed instruments.

Meanwhile, Asumu is assigned the whistle in his high school�s brass band and is not too pleased with not having the chance to play the drums.

Discovering the self-multiplying Dorotabou, the Oni realize they will have to unify their powers using taiko to defeat the Makamou. As Hibiki trains harder to unleash his Crimson form, Todoroki struggles with his lack of drumming skill, but a pep talk from Hinaka might just be what he needs�

Everybody is out, either enjoying their day off or hunting down Makamou, leaving Asumu and Akira to tend to the sweet shop. Ibuki crosses paths with a strange couple that are dressed in full kimonos in a busy city while Hibiki and Todoroki track down a Bakeneko group hidden deep within a mountain forest.

Zanki is attacked by a white Puppet, and the damaged disks lead Hibiki and Todoroki to track down the group of Bakeneko hiding in the forest shrine. Back at Tachibana�s, Tsutomu reveals his relationship to the Oni world to Asumu and asks what he wants to do in the future.

At the same time, Hibiki continues to train the boys, but Kyousuke�s arrogance and lack of physical skill holds him back, until he erupts with frustration at Hibiki�

Despite earlier warnings about transforming again, Zanki steps up and rejoins the fight against the growing hordes of Makamou, but it takes an extreme toll on him, but he intends to help Todoroki regain his strength no matter the cost�

Despite seeing him fall in battle, Ibuki is shocked to see Zanki appear in Todoroki�s room, but when Hibiki and Ibuki reveal Zanki�s fate, Todoroki angrily refuses to believe his mentor could be dead. As Kyousuke follows one of the boys that bullied him with Asumu on his trail, the approach of Orochi continues�

Leading the Oni to a stone with ancient Oni script on it, the Man and Woman make their next move towards preventing Orochi, but the cost of stopping it may be too much for Ibuki to bear. Meanwhile, Kyousuke becomes increasingly obsessed with becoming an Oni, with his focus on his training consuming him, while Asumu questions what it means to put your life on the line to protect others�

While trying to fight a new Phantom that has appeared looking for a new Gate, Koyomi is suddenly attacked by Medusa.

Haruto must find a way to defeat Caitsith before he converts Takagi while also helping Koyomi discover the truth of her origins.

The National Security Agency's Section Zero obtains a green Magic Stone, and so Kizaki abducts Wajima so he can commission his own Wizard Ring. At that time, a Phantom arrives to create a new Phantom from a child traveling from Akita to Tokyo, leaving Haruto alone on his mission.

While hunting down Gargoyle and having to deal with Kizaki, Kamen Rider Wizard appears to fall into a trap set up by Phoenix.

Haruto's and Kosuke's differing ways of handling things, from how to approach the issue on Phantoms to even eating doughnuts, causes a rift between the two magicians.

The three-way battle between Kamen Rider Wizard, Kamen Rider Beast, and the Phantom Hydra continues, with Oikawa's livelihood at stake as he is on the verge of becoming a Phantom. To try to get Kosuke to change his mind, Shunpei and Rinko tell him what really happens to Gates when they fall into despair.

Kosuke discovers Medusa's true identity as the school-aged girl Misa and attacks her, only for Rinko to arrest him. Going on the magician's hunch that she's after another schoolgirl as a Gate, Haruto and Shunpei attend the school to try to thwart Medusa's plans.

When it is discovered that Mayu is the twin sister of Misa, the girl who has become Medusa, Mayu makes it her mission to seek out the one part of her sister that is still alive within Medusa, even though Haruto believes it is better to save Takako first.

With Sora's words in mind, Haruto meet Wiseman to get answers. Meanwhile, Rinko investigates an arson case with Shunpei, only to discover that a man with a caged myna bird may be a Gate.

The group must protect Nemoto from both the Phantom Raum and the police who want to question him on an arson case. However, can they clear Rinko's name before it's too late?

Haruto is alarmed to find Kizaki has disappeared after he has been asked to search for Fueki, who kidnapped Yuzuru to seek out another person worthy of becoming a magician. After Kamen Rider Wizard saves Saionji, a novelist, Saionji reveals he is looking for a young woman to give him the inspiration to write again.

Saionji reveals it is Koyomi who he has been looking for all this time, saying he met her once 10 years ago. Meanwhile, Sora warns Nitoh about White Wizard, and he prepares to face him in battle as Kamen Rider Beast and Beast Hyper.

With the knowledge that Fueki is not only White Wizard, Koyomi's father, and the Phantoms' leader Wiseman, Haruto, Kosuke, and Mayu work together to try to discover his true plans.

With Yamamoto and Yuzuru both Kamen Rider Mages under White Wizard's thrall, Haruto and Koyomi are kidnapped to begin the new Sabbath. After Kosuke is approached by Beast Chimera in his dreams, he goes to assist Rinko and Shunpei to help save Haruto and Koyomi.

Hase and Jonouchi transform into Armored Riders Kurokage and Gridon, but something strange happens during their fight with Baron against Gaim and Ryugen. Later, Kouta tries to get a part-time job at a pastry shop, only to be disturbed by the effeminate head chef.

After easily defeating both Kurokage and Gridon, Kamen Rider Bravo steals their Lockseeds and sets his sights on defeating all of the Armored Riders. Kouta is angered that Oren has made it his mission to defeat all of the Armored Riders, but Kaito just tells him to beat him to get it over with. Before long, Bravo issues a challenge to Baron, but it is not Baron who he is really after.

After Hase transforms into an Inves, Gaim tries to take him out before he can do much damage but finds it difficult to harm someone who he believes is still human inside. Meanwhile, Baron does his best to combat Zangetsu Shin but is overcome by Kurokage Troopers and captured. And Mitsuzane, who realizes his brother is their foe the white Armored Rider, infiltrates the Yggdrasill Corporation headquarters on his own to see what is truly going on.

With Kouta and Kaito both captured by the Yggdrasill Corporation, they are brought to Ryoma Sengoku who reveals that he created the Sengoku Drivers and Genesis Drivers, and reveals the truth about the Helheim Forest to them. Elsewhere, Mai and Zack try to convince the other teams to hold off the Inves Games due to the damage they cause and how they are missing most of the Team Leaders. While under Yggdrasill's custody, Kouta is approached by DJ Sagara who tells him more of the truth behind the Yggdrasill Corporation, and suggests that he do something about it.

Mai wants to know why Kouta has been hiding from her, and he reveals the truth to her about Helheim Forest, as well as the Inves and the fate of Yuya, upsetting Mitsuzane, who is still under orders from his brother. Meanwhile, Kaito plans to finish his fight with Demushu.

Kouta is knocked unconscious by Ryugen's backhanded attack, and Baron fights Ryugen for acting so cowardly. Meanwhile, Takatora mulls over the idea of having to cull the Earth's population down to only one billion people through the use of the Sengoku Drivers, remembering back to the days of first developing them, unaware that even then Ryoma was conspiring against him. When Kouta regains consciousness, he explores Helheim Forest once more, only to be approached by someone unexpected.

With the world falling into chaos thanks to Ryoma, Zawame City has become an isolated place infested with Inves. Kouta's sister Akira, along with others in shelters, go outside to call for help. Meanwhile, Redyue broadcasts an announcement over the radio to the whole world stating that Helheim will completely take over the Earth in a year. At the same time, Inves are commanded to hunt the citizens of Zawame City.

Yoko confronts Mitsuzane about his actions as Zangetsu Shin and whether or not he will tell Kouta, while Redyue plans on using human technology to further her own goals as well as bring back Rosyuo's queen. But to do that, Redyue requires a sacrifice.

Rosyuo begins the invasion of the Earth by opening Cracks around the world. Kouta, Kaito, and Yoko plan an assault on the Yggdrasill tower to stop him, while Kouta also seeks out Akira. However, Mitsuzane has other plans after seeing Mai, again.

Kouta tries to prove that he has not changed, despite all Kaito has seen in Helheim, and helps the others clear Zawame of Inves. However, Mitsuzane and Ryoma discover that Mai, who has been taken ill, is now the host of the Golden Fruit, and wonders why Rosyuo has placed it in her.

As Gaim and Ryugen Yomi continue their battle, Kaito realizes that there is only one way for him to surpass Kouta now that he possesses the powers of the Over Lord King.

While Shinnosuke and Kiriko investigate Roidmude attacks on transportation vehicles, Brain and Heart instruct Chase to follow a criminal named Crush.

While Shinnosuke is still under the effects of Brain's poison, he must figure out how to stop the Crash Roidmude from obtaining explosives from the Font-R company, when its president prevents the Special Investigations Division from looking into his factory.

While Chase is haunted by the fact that Kiriko and Mr. Belt's voice appears in his memories, Shinnosuke escorts a popular fashion model who has come to the police station because she fears she is being followed by a supernatural creature.

Mashin Chaser is revealed to be Kamen Rider Protodrive, but Mr. Belt cannot figure out how to get him to return to his original self. Meanwhile, Shinnosuke tries to figure out why Rira is being targeted and/or protected by Roidmude 096.

Mitsuhide Nira of the 1st Division pays a visit that leaves an unpleasant taste in the Special Unit. Meanwhile, a Roidmude targets Hayase, Shinnosuke's former partner. When things get out of hand, Shinnosuke has no choice but to reveal his identity as Drive to the public.

Shinnosuke’s secret identity as Drive is now public knowledge. Chief Honganji, who had known this all along, purposefully leaked this information to the media, calling it a “move ahead against the enemy”. He thinks that now that Roidmude 001 has started to move, making Drive a widely known hero is a more advantageous circumstance. Also, the fact that Roidmude 001 could be involved in Shinnosuke’s father death has arisen. What kind of powers does Roidmude 001 have? Meanwhile, Chase has helped Drive once but he is still confused. What is he fighting for? What is he supposed to protect? In the middle of his thoughts, both Shinnosuke and Heart pay him a visit at the same time…

Shinnosuke has fallen at the hands of Freeze's Over Evolved State, and the Special Investigation Unit has no choice but to disband. Meanwhile, Chase works to find a way to bring Go back to his senses.

After being revived, Shinnosuke has gained a new power in the form of Type Tridoron. However, he can’t help but be worried by Freeze’s final words. Meanwhile, a Roidmude has stolen reports from a crime lab. The stolen documents were all cases that involved Shinnosuke’s father, Eisuke Tomari.

Takeru Tenkuji strives to be a Ghost Hunter just like his late father, Ryu Tenkuji. On his 18th birthday, he receives a Ghost Eyecon as a present from his late father's spirit. However, a mysterious monster appears, demanding that Takeru hand the Eyecon over. Takeru boldly confronts the monster, but...

Takeru has been revived from the dead and has obtained the power to transform into Kamen Rider Ghost. However, he now has only 99 days to obtain the Eyecons of 15 heroes. Akari, who can't cope with the lack of any logical and scientific sense this situation makes, is called by her professor to where another strange event has occurred. Meanwhile, Onari, knowing that the Gamma are targeting the hero Eyecons, instructs Takeru to go wherever strange events happen and sends him to the same place. Takeru finds out from the Hermit that the next hero to appear is Thomas Edison. However, he has no clue how to summon him. Meanwhile, the mysterious man in black is meeting with an inventor. What is his objective now?!

The apparent sounds of a machine gun in a supposedly abandoned school, about to be remodeled, catch the attention of Takeru and he decides to investigate. Takeru rushes to the elementary school to find the Gamma. As Takeru fights against the Gamma, the Rider that stole the Nobunaga Eyecon appears again and attacks Ghost. As this Kamen Rider attacks Takeru, he allows the Gamma to get away!

The fear and insecurity of his last two defeats against Specter have made Takeru unable to become visible. An uneasy Akari begins to fear that Takeru will no longer be visible to her, even with the Shiranui powder. A new client seeks the help of the Mysterious Phenomena Researchers. Sound has disappeared around Kosuke Kimijima, a young prodigy composer. It is like Beethoven... Takeru, Akari and Onari pay a visit. While unable to hear, Kimijima starts composing non-stop and Takeru is unable to warn him that he is in danger. A new Gamma appears and Takeru transforms into Ghost. However, Specter appears again to get in his way.

With all 15 Eyecons gathered, Saionji barges his way into Daitenku Temple to the Monolith to demand the ability to take over the world. However, Takeru is taken into a giant mandala called the Great Eye that has appeared in the sky and is asked one question by a disembodied voice: "What is your wish?"

Takeru's wish to bring Makoto's sister Kanon back starts their search for the Eyecons all over again, but without the Gamma to point the way where they have scattered, Akari and Onari are worried that they are too late to bring Takeru back to life. The return of the Gamma Superior means they are on the right track, but something happens to Takeru after he transforms into Kamen Rider Ghost, again.

Alain, now able to transform into Kamen Rider Necrom, makes easy work of fighting Ghost and Specter. However, for Takeru, it was Alain's words, not the defeat, that bothered him the most.

Strange incidents of young women being attacked within a thick mist have started to happen. A woman able to make predictions about the next attacks, Miwako, appears. Onari firmly believes her while Akari denies everything. All the same, they go to the predicted area. The prediction is fulfilled and a Gamma attacking women appears. Takeru is busy looking for the Newton Eyecon so Onari decides to confront the Gamma with his staff...

When the spirit of Himiko isn't the cause of the strange happenings in the city, the Himiko Eyecon leads Takeru to the Gamma World for a revelation. With Makoto also out of action during the continued attacks on young women, Akari and Onari step forward to try to discover the reason for the attacks, but Akari must first improve the Shiranui formulation.

Takeru is horrified at the things he witnessed in the Gamma World, but now with all 15 Eyecons gathered once more with Alain now an ally, he wonders what to do for the future. Their plans are waylaid when Adel sends Jabel to the human world once more to kill Alain.

Akari and the others cannot believe that Makoto, who saved Alain from harm, was only an Eyecon. Takeru, now knowing that Makoto’s body is in the Gamma world, intends to go but the others stop him. Kanon offers Alain’s help but Takeru does not trust him. After witnessing this, Kanon goes by herself to convince Alain. Sightings of a Mouse Monster have been reported. It seems to be different than a Gamma. On top of that, Goemon’s ghost has possessed Onari. Alain is still the target of assassins and he still cannot get used to a flesh body and the fear of death. The appearance of a red warrior will further complicate things.

After evading its attacks, Ghost Mugen Damashii is able to connect with the Perfect Gammaizer.

Takeru witnesses Adel's sad memories of losing his mother. Adel, on his part, connects with Takeru's sad memories of the loss of his father but the words he gives Takeru are completely unexpected…

"I killed your father."

Adel is Ryu's murderer?! Takeru becomes unable to hold back his rage.

Edith, as Kamen Rider Dark Ghost, welcomes Takeru, Makoto, Akari, Kanon, and Onari to the Gamma World and brings them to Adel but they are stopped by Igor and other Gamma. Igor approaches Akari and she decides to slap him repeatedly until he snaps out of it.

Takeru is on his last day of life as the Ganmaizers revive once again and assimilate Adel's body in order to create an entity completely fused with the Great Eye! The Ganmaizers have decided that humanity deserves to be eradicated, due to their inconclusive emotions and systems of logic and reasoning. Takeru is forced to watch them destroy large sections of the city! Makoto and Alain fail to stop them as their power is greater than normal! All hope lies in Takeru who tries to deal a final blow to the Ganmaizers but to no avail! They watch as they begin to disappear large amounts of people from the city...

Emu, a clumsy pediatrics intern takes young Sota, who is suffering a mysterious illness, to the announcement event of the latest "Mighty Action X", Sota's favorite game. Emu became a medical doctor in order to save someone's life because his life had been saved once through surgery.

However, a mysterious virus emerges from Sota's body and the event turns into chaos. Emu hears from Asuna, an employee of the Ministry of Health, that transforming into a Kamen Rider can save the patient. Emu takes on this "operation" and inserts the Mighty Action X Gashat into the Gamer Driver, transforming into Kamen Rider Ex-Aid!

Becoming Kamen Rider Ex-Aid, Emu now must serve as both a pediatrician and a member of CR. A gifted surgeon named Hiiro Kagami comes back from the United States and is not only the son of the director, he’s also Kamen Rider Brave. This results in a clash of ethics when it comes to dealing with patients.

Emu follows a patient who’s fled in fear of a doctor and encounters Taiga, who transforms into Kamen Rider Snipe. Once Emu learns of the past connection Taiga had to CR, he visits the dark hospital Taiga resides in to rescue the patient.

Emu cannot transform into a Kamen Rider since Taiga stole his Gashat. Medical Examiner Kiriya Kujo appears before a crestfallen Emu. He brings a Bugster-infected patient and offers to steal back Emu's Gashat in exchange of helping Kujo out with his prodigious gaming abilities.

When the thief of the 4 new Rider Gashats is infected with the Bugster virus, Emu and Hiiro clash about saving his life or not, and the identity of the mysterious Kamen Rider that is attacking the others is finally revealed.

The girlfriend of the student that the Bugsters were after has contracted the Game Disease. Hiiro transforms into Brave and succeeds in separating the Bugster from the girl.

A hospitalized patient showing two symptoms of the Game Disease has appeared. Emu and Hiiro transform and succeed in separating the two Bugsters from the patient. But Genm appears again to interfere, letting the Bugsters escape.

Taiga manages to capture the Bugster which escaped in the last episode and obtains the Jet Combat Gashat, holding the Bugster, and thus the patient, hostage in exchange for the other Riders' Gashats. When they arrive to challenge him, he decides only he is needed to fight the Bugster, and tries to destroy Ex-Aid and Brave.

Graphite infects the Deputy Director-General of the Ministry of Health with the Bugster Virus, while the doctors at the CR fall out over the most important course of action: Save the Patient or defeat Graphite?

Unable to control the powers of the new "Drago Knight Hunter Z" Gashat only by himself, Emu discovers that to do so he must convince the other Kamen Riders into join forces with him. Once he tricks them into doing so, the time comes for their showdown with Graphite.

Emu gives Kiriya another chance to earn his trust. Kiriya then takes the chance to finally reveal Kuroto's intentions and expose him as the Black Kamen Rider that is working with the Bugsters.

With Christmas around the corner, Emu runs against time to defeat the Salty Bugster again and save another patient, while Kiriya's investigation leads him closer to the truth, but his life is in danger when he faces Kuroto's new power.

With the Bugster infection spreading rapidly, the authorities can't hide the disease from the public anymore. After Kiriya's death, Kuroto starts targeting the other Kamen Riders for their Gashats, but Parad approaches Emu, offering him a blank double Gashat which will allows him to attain a new level of power…

Ex-Aid, now as two, get into an argument about defeating Genm or the Aranbura Bugster. They both seem to be Emu, but Genm and the Bugster take this opportunity to escape. Emu reverts to his human form and falls unconscious.

Wanting to save Dr. Shirakawa, Emu asks Hiiro to perform a surgery on his cancer. He has his Gashat back and faces the Aranbura Bugster to also cure Shirakawa's game illness. Will the surgery succeed? What will happen to Ex-Aid?!

Taiga tries to find out more about Emu's infection, and starts to discover the secret that might be why Kiriya was killed. Meanwhile, using data collected from fights with Mighty Brothers XX, Parad makes his move and reveals his new form: Kamen Rider Para-DX Level 50.

Emu thinks Taiga and Hiiro attacked him since he is the source of stress for Nico, who is suffering the Game Disease. He does not realize the true intention of the other two riders is to eliminate the Bugster virus residing in Emu himself, who is unknowingly infected with the disease as well.

Brave attacks Ex-Aid again but Revol Bugster and some grunts appear to…defend Emu! He is further convinced he is the source of Nico’s stress. Genm Level X appears and attacks both riders. He succeeds in stealing all of Hiiro’s Gashats and seems intent to do the same with Emu’s.

A lovable hamburger Bugster named Burgermon appears. Emu transforms into Ex-Aid, but attacking it causes the game disease patient to suffer from stress. What is this?

The CR accommodates an employee of the Genm Corporation’s development department. A game called Ju Ju Burger is under development with a game virus infection, and Burgermon seems to be separated from the game. Burgermon acts like an adorable child; he doesn’t seem so bad. As expected, Emu will have to deal with what’s in control of his head.

"Hiiro, are you hiding something from me?" Emu calls out Hiiro on the roof of the hospital. In the last battle, Genm tells Emu that he saved the Bugster because his body told him to do so. Emu also suffers from serious headaches after every transformation since creating the Mighty Brothers XX Rider Gashat. And most of all, Emu is incompatible with the surgery and yet he can still transform into a Kamen Rider. Everything is starting to come together, so what will Hiiro's response be? Meanwhile, Kuroto Dan returns to Genm Corp., and using the Gashacon Bugvisor, he begins to spread the Bugster Virus...

Emu finally learns of the horrifying truth that he has the game illness. The Bugster virus in him acts up and he collapses to the ground, though for some reason no Bugster has appeared...

Emu later wakes up in CR with his personality completely changed to that of "Genius Gamer M". When a new Level 30 Bugster emerges, Emu transforms into Ex-Aid with delight, and fights as if he were playing a game while no longer concerning himself with the patient. Just what has happened to Emu?

Taiga and Nico meet a high school student named Daisuke who is infected with the Bugster Virus and calls both Emu and Hiiro for their help. Parado suddenly appears and Hiiro faces him in his new form while Emu is hesitant on joining the fight.

Emu and Hiiro learned from Poppy that Kuroto was the one who had suggested Emu to CR. Meanwhile, a police detective is investigating the Zero Day case, causing him to interrogate Kuroto's father, Masamune. During the investigation, he gets infected by the Game Illness. In order to save him, Emu confronts Masamune.

Kuroto falls victim to the Bugster virus and is aprehended by the authorities. Despite everything Kuroto did to him and his friends, Emu is determined to treat him, but the others are wary, wondering if saving Kuroto's life is worth the effort, or even if he will be grateful for it. On the other sides, Hiiro finds some very useful information from Kiriya Kujo's belongings while Emu receives an emergency call that a Bugster is rampaging on a certain location.

Recovered from his infection, Kuroto resumes his plans to complete "Kamen Rider Chronicle" and the members of CR seem to have no way to stop him, until Taiga gives Emu a new Gashat that brings forth a power never seen before.

The fierce battle between Ex-Aid and Genm has now come to an end. Meanwhile, a woman who was injured, Sora, is brought to Emu and Hiiro. Sora's band members argue, when suddenly all 3 of them are taken over by Bugsters! And on top of that, when Emu tries facing them alone, a young man appears yelling, "Yossha Lucky!"

Recently, Emu has been feeling a little worried. He is very quiet and hasn't talked much since Poppy Pipopapo suddenly disappeared. Just then, Hiiro is shocked by the sheer number of emergency calls coming to CR, all reports of the game illness! As the only CR doctors, Emu and Hiiro rush to the indicated locations, but what they find there is an unbelievable sight...

Kamen Rider Chronicle has already begun! Para-DX has joined the game and defeated the first round of the general players, giving them a Game Over as Emu watched them disappear before him. Kamen Rider Chronicle is being sold at an extremely fast rate, which catches the attention of the Ministry of Health. To avoid any form of confusion, Kyotaro Hinata orders a temporary halt on the actions of the doctors in CR. However, a game disease patient escapes from CR in an attempt to cure his own game disease, which leads Emu to chase after him. Then suddenly, Poppy Pipopapo appears before them with a new Driver and a Rider Gashat of her own…

Thanks to the public announcement by the Ministry of Health, the number of Kamen Rider Chronicle players seems to have decreased significantly, which would subsequently reduce the amount of game disease patients. However, unbelievable information about Kamen Rider Chronicle is released by Ren Amagasaki, the new CEO of Genm Corp. There is a hidden component inside Kamen Rider Chronicle, one that is said to dramatically increase player participation! However, Taiga, who was suspicious of the love and go CEO's actions, goes into Genm Corp. to confront him himself...

Emu managed to notice Poppy smiling after the Rider's battle against Lovelica. With her sudden change of heart, Emu believes that she was suddenly swept up in all the commotion. Although he was attacked by Kamen Rider Poppy, Emu does not believe she is a bad Bugster. When Kamen Rider Chronicle starts up once again, Poppy Pipopapo is summoned. When Emu confronts her, he shouts "You aren't like this!" to her, just as she appears to deliver the final attack at the Riders who violated the game...

It was Emu who managed to return Poppy Pipopapo back to normal thanks to the bond they share, but it was not a time for relief. Suddenly Parado begins to manipulate Emu! "Let's do this, the most exciting of all games!" Emu managed to remove the Gashat Gear Dual that transforms Parado into Kamen Rider Para-DX and uses it himself! Just what on Earth is going on?! Finally, the points connecting Emu and Parado are beginning to reveal themselves...

Ex-Aid, Brave, and Snipe have all been defeated at the hands of Kamen Rider Para-DX Level 99! Also, Parado begins to manipulate Emu's body as his own in order to retain the infection. Much to the other Rider's surprise, Poppy brings out another Proto Mighty Action X Gashat and a Gamer Driver! Poppy had found them thanks to her revived memories of a young Kuroto. What is the meaning behind this Gashat? Poppy manages to use the power of Level 0, in the hopes of bringing Emu back to normal...

No one can hide the fact that they are upset about Kuroto's revival. How was he able to return? What is Kuroto's true intention by making this Continue a reality? Meanwhile, Emu cannot forgive what Kuroto did to all those patient's lives. He realizes that in order to eliminate Kamen Rider Chronicle, his cooperation is required, but Emu is getting tired of his attitude...

Ex-Aid and crews have gained the right to challenge the advanced Bugsters in order to clear Kamen Rider Chronicle. The three advanced Bugsters are Parado, Graphite, and Lovelica. The time of the final battle against the four Kamen Riders is at hand! At last, the curtain rises on the scene of the last battle! However, a disturbing darkness suddenly begins to appear...

Masamune Dan as Kamen Rider Cronus instantly killed Lovelica with his Pause attack, which freezes the game in time! The Bugsters and CR are greatly upset by Cronus' sudden appearance, Parado frozen in fear. Furthermore, it seems that the Proto Gashats being monitored by the Ministry of Health have been stolen by him! Now the doctors have been deprived of the data of the past Ride-Players. Emu goes to visit Masamune Dan, once again the CEO of Genm Corp. ...

The fact that Hiiro has betrayed Emu weighs heavy on the members of CR. If Hiiro is working with Masamune, then there can only be one reason for it. With everyone on the ropes about the situation, suddenly both Parado and Graphite show up in CR! To counter against Cronus, they ask Kuroto about Kamen Rider Chronicle's final boss, Gamedeus, the only being who can defeat Cronus. Just then, Brave confronts Ex-Aid as he is responding to an emergency call...

Apparently Hiiro wasn't the only accomplice that Masamune had in the palm of his hand! Cronus suddenly summons Kamen Rider Lazer Turbo Level 0 into the fight! In order to further expand the presence of Kamen Rider Chronicle around the world, Lazer Turbo stands before the Doctor Riders in an attempt to keep them from ending the game! Much to the shock of everyone, Kamen Rider Lazer Turbo finally reveals his identity...

Genm Corp. announces a new addition to Kamen Rider Chronicle, the "Cronus Capture Quest", and despite knowing what dangers lie ahead, countless new players join the game! Meanwhile, Emu is still reminded of the message Kiriya said to him before Masamune took him away. Kuroto completes an invincible golden Gashat holding an unbelievable amount of hidden power! Ex-Aid and the others rush to stop the "Cronus Capture Quest" as Brave and Lazer Turbo stand in their way once again...

Ex-Aid finally went Muteki and was able to beat Cronus! Masamune, who does not like the fact that Ex-Aid was able to attain a power that exceeded his control, angrily forces Hiiro to work for him as he claims Saki as a hostage! Brave forcibly renews his resolution, and this time he is able to transform into Legacy Gamer Level 100! Emu is more confused than ever, while Taiga is the only one who truly understands just how painful Hiiro's decision truly is…

Graphite mercilessly attacked the body of Taiga which forced him out of his transformation! The injured Taiga has been rushed to the hospital immediately, but there is a high possibility that his heart has been damaged. Moreover, it seems that it would take an expert-level of surgical expertise in order to save his life. After returning to Masamune, Hiiro's father and Asuna make an urgent phone call. The director asks Hiiro to perform Taiga's surgical operation. Just what decision will Hiiro come to in the end?

In order to deprive Ex-Aid of his transformation abilities, Cronus decides to target Parado directly. Para-DX without Emu is still not perfect, so he is beaten easily. Even so, Ex-Aid cannot stop chasing Cronus. However, Cronus was planning an underhanded scheme. Nico's game disease, which just started to show symptoms, belongs to that of Gamedeus, the Last Boss of Kamen Rider Chronicle! In order to defeat Gamedeus, Ex-Aid has to defeat both Graphite and Parado! Just then…Parado's hands begin to shake violently…

Parado has been defeated, and Emu has lost the ability to transform into Ex-Aid! Following Parado's annihilation, the other Riders team up in order to defeat Cronus. Brave, Snipe, Genm, and Lazer Turbo, all alternate the Hyper Muteki Gashat in order to counteract Cronus' Pause. Meanwhile, Emu was deep in thought. The fear of death that he felt at the moment of his extinction, even if he was a Bugster, he shared the same feeling as he did in that moment. Just then, Emu takes out the Mighty Brothers XX Gashat…

Kamen Rider Chronicle has been reset thanks to Masamune's special ability! Thanks to his Bugster infection, his hidden power has awakened, and the game is reset to the moment before Emu received the Hyper Muteki Gashat! Finally, with Parado having already been defeated, Graphite is the only game character left in order to clear Kamen Rider Chronicle! Brave and Snipe both challenge Graphite with a burning fighting spirit. Meanwhile, Emu believes that Graphite infected with Gamedeus' virus may be the only one strong enough to defeat Cronus. However, Graphite refuses to cooperate with the Riders…

The Last Boss of Kamen Rider Chronicle, Gamedeus, is finally born! If you defeat Gamedeus, then the game will end! However, at the moment of Gamedeus' revival, massive amounts of the Bugster Virus spread throughout the city! The number of infected patients are increasing, as well as the number of people being rushed to the hospital. While the doctors attend to the patients, Ex-Aid and Para-DX team up to fight Gamedeus! But their strength is far too weak against Gamedeus, as he sends them flying easily. At the same time, two people were confronting each other. Kiriya and Kuroto, both transformed, clash fists to see who's fate will be decided in the end…

Suddenly, the Gamedeus virus begins spreading through the streets! Masamune becomes Gamedeus Cronus and appears before the other Riders, as he summons Nico into the World of Kamen Rider Chronicle! Nico is the one who is qualified to challenge the Last Boss of Kamen Rider Chronicle as a Ride-Player, but it seems clear that Masamune is going to try to Game Over the player who is closest to beating the game in order to reset it. In an attempt to save her but unwilling to let the others follow, Taiga uses the Chronicle Gashats seized from patients and goes to find her. However, the other Riders cannot enter the World of Kamen Rider Chronicle! Just what will happen to Nico's fate?

Gamedeus Cronus has grown massive and become the strongest Last Boss! The Gamedeus Virus expanded and the pandemic has gotten worse. The Gamedeus Virus can now be transferred from person to person, turning the infected into Bugster Virus foot soldiers! Two Bugsters witnessing this symptom, Parado and Poppy Pipopapo, decide to take action. "There is something that only us Bugsters can do…" Poppy says as she rushes to Ex-Aid…

Though Gamedeus was finally destroyed at the cost of Poppy Pipopapo and Parado when they extracted the Bugster from his body, Masamune Dan survived and takes advantage of Emu no longer being able to use Hyper Muteki. The Kamen Riders are at a huge disadvantage, while Cronus doesn't hold back, and initiates Pause. All of the Kamen Riders' movements are frozen in time, and he prepares to kill them, starting with Emu…
