Scenario
In the manga, Hanako Ichinose becomes acquainted with Taro Tabe who, strangely, can inherit the traits of whatever he eats. Later in the story, Hanako is abducted by a group of thugs and Taro arrives on the scene. However, rather than rescue her, Taro devours Hanako whole.

Consequently, Taro inherits Hanako's karate skills and fights off the bullies. Afterwards, Taro finds himself in the presence of a church and forcibly regurgitates Hanako, who is unharmed.
