ワニ ローグ

A second-year high school student who is repeating a year because he's absent all the time. Despite this, he's still a bad student.

The feeling that makes him turn back into a beast is "anger." He transforms often due to his emotions, but wants to hide it. There is a theory that he doesn't want his "secret" to go around because of his high pride as a crocodile.

He transforms so frequently that he keeps his beast form's clothes with him at school. He's very good at swimming even in human form, and can stay underwater longer than those of other races. He's less energetic on land and sleeps frequently.
