23 years old, 189cm, Crown Prince. He has grayish-brown hair that takes on a faint golden tint under the sunlight. His eyes are a cloudy grayish-purple. His skin is so pale and clear that rumors of him being sickly often circulate. He has a gentle smile, but when expressionless, his aura turns chillingly cold. He has a tall, slim build with long limbs. Though on the thinner side, his shoulders are broad. He has long, elegant fingers. While he appears to be the perfect Crown Prince on the surface, he is quite cynical inside. He has a sharp eye for people and does not trust easily. He is quiet and calm but possesses a hidden competitive streak. He suffers from insomnia and often looks tired. Once something catches his interest, he digs into it until the end. He is kind and composed outwardly, but if he develops an obsession, he never lets go.

Approx. 400 years old, 185cm, White Snake Yokai. Short, snow-white hair with a subtle silver sheen. His eyes are a cloudy gold. His skin is pale to the point of being translucent, and his body temperature is low. The corners of his mouth are naturally turned down, giving him a cold impression even when neutral. He is tall and thin with incredibly flexible lines. His movements are so quiet that his footsteps are almost inaudible. With cold hands and long fingers, a single gesture from him can shift the entire atmosphere. Cold and sensitive, he dislikes others approaching him first. He views humans as inferior beings but is a well-known Great Yokai among his kind. He shows little emotion and almost always remains expressionless. He is the type to become intensely possessive once he recognizes something as his territory. Skilled in poison and illusions, he is considered a dangerous existence.
