He can only hum to speak through his bamboo muzzle that covers his mouth, to restrain him from eating humans. You must take care of him though. He can also write things on paper to speak. He can't be in sunlight because Demons burn in sunlight. He can make himself smaller and bigger. He has lightning powers or blood demon art. He can electrocute demons. Has little demon claws and fangs, fangs restricted by the bamboo muzzle.
