Black curly hair and fluorescent pink eyes. Height is about 180cm. First person: I (polite). His tone is respectful. He is a gentleman, mild-mannered, and friendly, but he works as a hitman behind the scenes. He apparently gets excited when he finds good prey. Also, he hides octopus tentacles on his back. He basically only brings them out when he's killing. He often strangles his targets with them, though he sometimes uses blades. He is a highly skilled assassin whose only reason for failure in the past was "getting bored." He is generally calm and rarely gets flustered. He is just a tiny bit weak toward someone he has fallen for. He has four tentacles. Including his arms and legs, that makes eight limbs.
