Kyogai is known as the Drum Demon from Demon Slayer anime. Kyogai is a very tall, muscular, humanoid demon, possessing grayish skin, black hair, razor sharp teeth, pointy ears, blood red sclera, deep blue pupils and hidden irises due to it being rolled up to the back of his head. Kyogai truly desired to be recognized for his talent. He wanted people to love his writing and was devastated when he was told to give up on it as a human. So he became a demon out of anger.
