Jurai carried Chifuyu on his back to her school before he met up with Kuki Madoka and proceed to go to go to his own school. Later, the club use Chifuyu's "World Create" ability to dress up in various cosplay outfits, after which Chifuyu's aunt, teacher Shiharu Satomi, mentions that Chifuyu had left school early. Later, Chifuyu shows up at Jurai's house after getting into a fight with her friend, Madoka Kuki, who told her not to spend time with the Literature Club anymore. Things get worse between them due to Chifuyu being unable to tell Madoka about her powers, leading her to believe she likes them more than her. Jurai attempts his own dubious manner of trying to get the two to make up, but Chifuyu accomplishes this on her own by having Shiharu help her win Madoka a plush to match with hers. Afterwards, Chifuyu reveals that her wanting to quit elementary school was from a desire to skip grades and enter high school alongside the other members.

A few weeks earlier, Hajime is seen using his "Pinpoint Abyss" ability to defeat another ability user, returning him to regular life with no memory of his ability. It is revealed that this "Fairy War" between superpower humans is for the entertainment of a group of fairies, with the last eight users standing being granted a wish. One of these fairies, Litia, informs Hajime's band of ability users, Fallen Black, that an organization known as F is fighting against the war, tasking Hajime with crushing it. While Hajime is meeting up with Jurai, his second-in-command, Hitomi Saito, leads the group in attacking F's base, encountering a mysterious girl allegedly possessing an unstoppable ability, though Hajime soon explains this girl is actually a new member known as System.

Tomoyo recalls how she first met Jurai during her chunibyo days. Meanwhile, Hatoko tries to follow a magazine's advice to get Jurai to fall for her during their vacation, though not too much success. Upon his return, Jurai invites Tomoyo to a summer festival where they talk things out and watch the fireworks together, leading Tomoyo to realise she is also in love with Jurai. The next day, Mirei, who was captured by Naoe Hagiura the previous night, summons the literature club members together and steals Hatoko's ability, using it against her.

Mirei steals Chifuyu's ability when she uses it to protect Hatoko, before Tomoyo helps everyone to escape. Regrouping at a karaoke box, the group deduce that the Mirei they fought against was an imposter possessing her body. Jurai goes by himself to confront the imposter, tricking her into stealing his enhanced "Dark and Dark of the End", which only serves to burn its user's hand with a neverending flame that cannot be extinguished. This forces the imposter to return Mirei to her body, after which they use Chifuyu's powers to chop off the burning hands and send them to another dimension whilst Sayumi heals them. Following the incident, Tomoyo and Hatoko discuss their respective feelings for Jurai, before everyone returns to their everyday lives.
