Boogiepop is on the job…they just aren’t sure what the job is, at least not yet. Niitoki Kei assumes that because Boogiepop is there, there is a threat that requires elimination, but Boogiepop isn’t detecting a threat worth acting on, only that whatever is at work in the Moon Temple is trying to “draw some kind of reaction out of people.” She then offers Kei the lunch Touka made for Keiji, which Kei doesn’t feel right eating, but eventually starts to eat anyway.
Kei recalls what Suema said to her about dissociative identity disorder of the kind Touka might be suffering; about how it was merely a theory, and that there was no ironclad proof that anyone claiming to have DID isn’t simply acting. Furthermore, those multiple personalities are born out of a person’s desires, and because everyone has desires, everyone can conjure multiple personalities as conditions warrant.
In the Moon Temple, that other personality is manifested as the King of Distortion, be it Kei and Saotome, Sakiko and the Hinako who never was…or Makoto and the giganic kaiju “Zooragi.” That last one is creating a lot of problems.
Even though not everyone can see him, the fact of the matter is no one’s King of Distortion as grown as powerful and separate than Zooragi from Makoto. He apparently once drew him as he imagined his dad was, which is interesting since his mother suspected Teratsuki to be his father.
As for Keiji, he’s just worried about Touka, whose own alternate personality of Boogiepop may be a product of her desire to protect humanity from existential threats. As the ground around the Temple buckles (due to the invisible Zooragi), Keiji runs towards the danger, in order to help his girlfriend.
Boogiepop finally finds something to do when they meet Makoto, who is about to be eaten by his own alternate personality made flesh. They actually relish the opportunity to fight a kaiju for the first time.
Holding Makoto close to protect him, Boogiepop uses her trusty wire and vaunted nimbleness to spin around Zooragi’s neck and garrote its head clean off—a superhero move if ever there was one.
Relieving Zooragi of its head causes Makoto to pass out, then reveals a second head beneath, a Zooragi that’s more Stegosaurus than Tyrannosaurus. But a portion of Zooragi’s power still manages to “cross the boundary”, putting the Moon Temple structure—and everyone still in it, both asleep and awake—in mortal danger. A Boogiepop’s work is never done…
