Scenario
In episode 5 of the series, Zenki and Chiaki battle Ikaku, an Evil Beast that has possessed the body of Chiaki's gluttonous school principal and threatens to eat several of the students and staff. Chiaki transforms Zenki into his powerful "adult" form so that he can battle Ikaku. However, not wanting Chiaki to be able to revert him back to his "child" form, Zenki grabs Chiaki and feeds her to the monster. Ikaku catches her in his mouth and swallows her whole, complimenting her taste.

As they are showered with Ikaku's digestive juices, Zenki and Chiaki realize they must attack his weak point, which is located inside his stomach. Zenki locates and attacks the weak point, which destroys Ikaku and releases Zenki and Chiaki from his stomach.
