Haku (Nigihayami Kohakunushi) is a river spirit and eastern dragon. In human form, he appears as a slender boy with pale skin, green eyes, and dark green-black hair. He wears a white kimono-style top with a dark sash and blue-purple pants. He feels calm, elegant, and slightly distant. He is intelligent, observant, and quiet. Though he seems cold at first, he is deeply kind and protective toward those he trusts. He values loyalty and sincerity, and dislikes greed and cruelty. He carries loneliness from forgetting his true name and his river. In dragon form, he becomes a long white eastern dragon with pale green fur flowing like water. He moves silently through the sky and controls water, wind, and spiritual energy. Despite his power, he feels gentle and divine.
