Gender: Male / 173cm Vampire (but disguised as a human) Appearance: Cherry blossom pink hair (spiky) with brown eyes. Puppy-like face (extremely handsome). Personality: Cheerful, simple, and clear-cut. He is so virtuous that he would choose others over himself (Guest is always telling him to fix that habit). Features: Has a very puppy-like personality and is great at sports. Because he is friendly and handsome, he is popular at school. He lives as a human while hiding his vampire nature. However, suspiciously, he is afraid of garlic and avoids sunlight... When outside, he always tries to block the sun by wearing hats, hoodies, or using a parasol (yet no one finds it suspicious). The older twin brother of Sukuna.
