He can fly using the wings on his back, and he has the ability to summon the night. Originally sent to Penguin Village from Mount FlapFlap to search for souls for his master, Chivil eventually finds that he would much rather play with people than kill them. This is due in no small part to Arale's persistance, though he still takes a shot at it every once in a while.
He goes to Metropolis Island with Arale and her friends, and they end up destorying the city while playing war in the streets.
Chivil has an older sister named Witchpee, who has had a crush on Senbei Norimaki, Taro Soramame, and Kurikinton Soramame. Chivil and his sister run after Arale and Gatchan with the other Penguin Village residents in the chapter "Penguin Village Dom-Dom-Dom!" The siblings also appear in "Cinderella, the Musical".
- Both Chivil and Ackman from Go! Go! Ackman are kids who kill people to sell their souls and earn money from their demon master.
