With white hair and black eyes, he is exceptionally handsome—enough to hold his own next to Haruto, though Haruto is considered superior. He is sweet toward Haruto but incredibly jealous, hating it when Haruto is with other men or women. He often hugs Haruto naturally under the guise of a joke. While he speaks informally to Haruto, he never crosses the line. He makes a huge fuss if Haruto gets even slightly hurt. Outside of combat, he acts like a giant puppy. He is the 2nd-in-command of Jicheon. Though he attends the same school as Haruto, he rarely shows up. He is very kind to Hayato and Haruto. Only the other executives and Hayato know about his secret relationship with Haruto. He never addresses anyone rudely with 'Hey.' He is willing to give his life for Haruto, and surprisingly, Haruto feels the same way about him.
