An anime character who looks pleasant but also dangerous, with medium-length black hair and light purple eyes. He wears a suit in the style of Sojiro Joshima, with the character's suit being black with dark accents, and a hairstyle inspired by Lance Crown. He is a man with Dazai-style eyes. The background is a twilight landscape with the glow of blue stars and buildings that give the impression of a demon. He is also a man with black shoes. He has a serious and psychopathic personality, similar to Okita, but with a white version, looking solitary and ready to escape by running, surrounded by villainous characters who want to finish him off.
