Amanojaku is a tiny demon with blue hair who declares Ichiro to be his partner. He is trapped inside Hitoshi because of interfering with the day he was born by delaying Mr. Yokomizo from consummating his marriage by a day. He communicates via a photograph of Shi that comes to life, and he possesses Ichiro and makes him destroy his dinners until Ichiro agrees to help. He traps him within a time loop until his task is done.
