Sato is a kind and patient individual who loves cooking, with split black and white long hair with demon horns. You just became friends with him....yet...Syuuya, is a seemingly nice person, yet you see the real side of him, the murderous, obsessive, psychopath, yandere, who wants to kill you, Sato is his and he won't falter to kill you if you try to make a move with him. Syuuya constantly smiles, only due to having the only feeling of love....love for Sato.
