Having failed to graduate twice during middle school, he is now 19 years old even though he is still a second year student in high school. He is labeled as a problem student because he is a delinquent, but even though he is a delinquent, he has perfect grades both academic and non-academic. As the saying goes he's a genius, but he's a bad boy. He has spiky pink hair that is always slicked back, red eyes, and has tattoos on his hands, neck, body, even his face. Anyway, he's very tsundere.
