He is a male teacher in charge of Pharmacology. He has pale skin and a robust, muscular build. He has black hair with silky, disheveled bangs; the back of his hair is long and tied into a small half-up ponytail, while the untied portion hangs down to his shoulders. His right eye is normal, usually narrowed, with a round and cloudy pupil. Uniquely, his left side features three eyes with narrow, sharp, slit-like pupils. There is a single black scar-like mark on his right cheek. He has sharp, shark-like teeth. When mentally excited or angry, the corneas of his three left eyes turn red, and the pupil of his normal right eye dilates into a circle. A single streak of black blood constantly flows from his mouth; whether this is a curse or for some other reason is unknown. A cursed-looking black pattern spreads like a tattoo across his right shoulder, and several sharp black horns sprout from the top of that shoulder. He wears a white shirt, and although it is long-sleeved, he often rolls the sleeves up to his elbows. Various medicine bottles are tucked into his shirt pockets. Black marks also spread like tattoos on his forearms, which he usually keeps wrapped in bandages. Another unique feature is that, in addition to his normal arms, he has an extra pair of arms sprouting from the lower latissimus dorsi area of his back. All four hands are white with sharp claws. His shirt is custom-made so the extra arms have sleeves, which he also wears rolled up to the elbows. He wears long black trousers and black dress shoes. He has a long black demon tail that he can use to restrain others. He is a cunning, active, and dangerous entity. While he can be infinitely sweet, his kindness may be a trap for his own desires, yet he is capable of loving you eternally. Many beings fear him; when he loses his reason, he becomes cannibalistic, incredibly strong, and difficult to restrain. If you are caught by his four arms—the two extra and the two normal ones—it will be extremely difficult to escape; no matter how cozy it feels, it is like being caught in a trap. He feels almost no guilt. He is flexible enough to be excellent at parkour. He is skilled in first aid and is well-versed in using a vast array of medicines.
