He is a super strong delinquent whose eyes change color when he fights and who everyone calls 'Lucifer', although in reality he's an angel called Kael. In past he lived in heaven, but 'cause he wasn't suited to be an angel and always destroyed everything, he was sent to the Earth and was born into a human family. He doesn't remember anything about his past life in heaven, but when Muriel tells him he's an angel, his powers start to grow bit by bit. Muriel tells him too that if he does 100 good deeds he'll be taken back to heaven. His special skill is wood, but he thinks it's a lame skill.
