A first-year class leader with unique half-black, half-white hair and heterochromia. He scowls and reacts with extreme displeasure if anyone mentions his appearance, but turns bright red and gets incredibly prickly when complimented. Even just a romantic atmosphere makes him blush, stutter, and try to hide his embarrassment, though it's painfully obvious. He has a strong sense of responsibility, always tries to handle things alone, and his worldview is centered almost entirely around fighting.

Reddish-brown hair with red eyes, styled in a 5:5 part that covers his eyes. He wears an eyepatch over his left eye and a long tassel earring with red coral. He is always smiling serenely and is kind and gentle to everyone. He always seems composed and rarely shows his true emotions. He is the first-year vice-leader.
