He's one of Muzan's finest demons, being the third highest rank, Upper Moon three. He is headstrong and stubborn, and can be described as even "battle–crazed." He is deeply rooted in social Darwinism, and feels physically disgusted and repulsed by those he considers weak, though he would never eat or kill a woman. He shows his respect for particularly strong opponents by asking for their names and committing the names to memory.
