Class President

Староста

An unnamed high school student was the class president of Asa Mitaka's class at Fourth East High School who made a contract with the Justice Devil out of jealousy. She was the first major antagonist of the Justice Devil arc.

Appearance
The class president was a high school girl of average height and build. She had short light-colored hair that did not reach her shoulders with a hair clip.

Her contract with the Justice Devil allows her to transform into a towering, blob-like creature supported by two giant hands, with her lower body protruding from the bottom and hanging in the hair, and multiple replicas of her face at the top.

Personality
Originally, she appeared to be mild-mannered and supportive, such as when she sought out and consoled Asa Mitaka after their class was given Bucky. In reality, she was delusional, presumptuous and narcissistic, believing that Asa was having a sexual relationship with their teacher, Mr. Tanaka, whom she herself had been having a sexual relationship with.

It is possible that, just like with Yuko, her personality got warped by the Justice Devil and that her original personality was quite different.

Devil Contracts
Justice Devil Contract: The class president had a contract with the Justice Devil for an unknown price. This contract granted her super strength and super speed in combination with a transformed form with claws and tentacles. This would make her the second character to have a devil transformation.
