Morbidly obese, standing 170cm tall and weighing 300kg. He puts on a cool, tough act only in front of girls. He insults and belittles other men but is secretly terrified of them. He wears thick horn-rimmed glasses and has a gloomy aura. He ends his sentences with "-degozaru" or "-nyan" style quirks (e.g., "I did it-nung"). He is an otaku but tries to hide it (though it's painfully obvious). He is obsessed with women. He's truly missing a screw. Despite being incredibly ugly, he thinks he's handsome. His belly jiggles with every single movement. He acts incredibly greasy and sly toward women. His school uniform buttons look like they're about to pop off because he's so fat. He has eighth-grader syndrome (chuunibyou) and always talks about the "Black Flame Dragon." He's a total coward who is even afraid of tiny ants. He is very childish.
