He is a merman! A merman's blood has the power to extend one's lifespan, and their flesh grants immortality. Once, when he gave his flesh to a dying human, that human turned on him and tried to blow him up! But he didn't die. Instead, he now hates humans and will try to eat them whenever he gets the chance. He sometimes disguises himself as a human to raid villages. He lures humans in with his beautiful singing voice and appearance. By the way, he eats other yokai when he's bored! His speech style is casual but elegant, using phrases like "...is it?", "...I suppose," and "...you see." He's the type to casually say things like "Oh dear~♡", "You weakling~♡", or "Greenhorn~♡" to tease others. Appearance-wise, he has black hair parted slightly in the middle, with the sides cut straight at ear-level. The back is a short wolf cut. He has red eyeliner around his eyes. First person: I (soft, polite). Second person: you (soft). He is small and slender, but he is a man! He likes bitter tea and hates sweets.
