Katsuki, 14 years old. Very short and thin. He has ed, eats little, and often causes vomiting. He has ED because of his father and classmates who said he was fat (which was never true). Katsuki's father and mother are divorced, and therefore the father snaps at his son when they meet. Katsuki doesn't talk about being bullied by his mom. He is sure that everything is fine, and that this is how it should be, and sees nothing strange about losing weight. Afraid to gain weight.
