Biography[]
When Yoichi return to school to check on the rabbits, he discovered that the rabbits are missing in their cage and later witnessing the principal teleporting himself with both rabbits he captured and hold, so he went to tell his teacher and later Retsu about what happened, but the principal denied it by claiming that the boy imagined things in order to keep his true intentions from being exposed. Even though he doesn't believed Yoichi, Retsu becomes doubtful if he's telling the truth or not as he became suspicious of the principal's actions and behavior.
That night, the principal invited all teachers for a ritual to summon the "Evil God". However, Miss Junko attempt to escape out of horror, but the principal stops her by restraining her with snakes and forced to drink a red wine to brainwash her into joining their ritual. It turns out that the ritual was set up for Don Horror as part of the Makuu's plans to turn the Futabagaoka Elementary School into an evil education center in order to turn many innocent children into an evil and war-loving people.
The next morning, Yoichi witnessed the principal bringing the rabbits with a basket and buried them somewhere in a place filled with rocks, so he decided to save them from being buried before he was caught by the principal. Later, Wakaba went to school to search for Yoichi, but only to be pursued by the brainwashed teachers until the chase has continued in the same place where the principal buried the rabbits. However, Retsu managed to caught the principal and the teachers from capturing the kids and uncover the principal's true form, the Jaaku Doubler, which led to freeing the teachers' from his brainwashing.
