Birdy fights with King Zero as Nejula corners Gelabu--whom ultimately commits suicide for his "pride" or "honor." Thanks to Birdy's way with words and the simple fact that King Zero's girl can't stand to see lots of people die, she detonates the falling satellite which was targeting the Union. Kashugeza turns out to be an undercover agent under Skeletsu's direction. Birdy is quite frustrated with the fact that Skeletsu tolerated the deaths of her fellow, innocent, Altarians in the terrorist attack in order to get a lead on King Zero.

An investigation team under Shyamalan's orders investigates the ruins of Sawajiri Village, even killing a policeman when Murota and Hayamiya decide to investigate. Birdy saves them from some of the armed men and fights the reconstructed marionette before she gets injured during an encounter with Gomez after defeating the marionette again.

Birdy and Tsutomu head to the Lost Bird to figure out a way to purge the Ryunka out of Sayaka's body. The two were able to do so, at the cost of Tsutomu's own body when he sacrificed it to allow Birdy to kill him again and purge the Ryunka parasite out of his body with Nejula in charge of containing it. The Japanese government had covered up the events as the JGSDF had mobilized in Roppongi. Due to the events, Sayaka loses some of her memories including her encounters with Tsutomu. Birdy once again merges with Tsutomu until a new body can be readied. Meanwhile, Gomez and his boss Revi had a conversation about whether Birdy is a threat, with Gomez telling Revi to take some precautions against her.

Birdy is informed of a break-out from an intergalactic prison, and manages to track down one of the rogue prisoners. Although she is ordered to apprehend the criminals alive, he was killed by the time she arrived on the scene. The only clue is a disguise chip, which dissolved the body.

Iruma, Birdy's contact on Earth for information, is kidnapped by the escapees to lure her into a trap. She escapes being nearly killed by a long-range gun and fights to a draw. She collapses before she enters the portal to her ship, however. Tsutomu has a weird dream, a blend between his own memories and Birdy's. This is when he discovers he is trapped in Birdy's body. He is thus forced to follow her schedule, including a signing some of his classmates attend, a photo shoot and a reality contest where he has to eat bugs. At the end, he learns that personality merging has begun.
