Chidaruma is the most powerful Devil, and the ruler of Hell and the Magic-Users Realm. Chidaruma has a skeleton head, big eye sockets and curly horns poking out of both sides of his head. He usually has his big long tongue sticking out over his sharp teeth. Like other Devils, he has a heavily muscled build with big arms and large wings. Currently, he dresses simply in a blue hoodie and with two arm guards with chains and spikes, he doesn't wear pants.
