Hachiouji Tarou is an average 2nd year high school student. Since his father died, leaving him as the head of the family, he’s been constantly pulling his brother out of trouble. One night, when he came back home, his mother's head was rolling on the floor, and an evil spirit had hold of his younger brother. Instead of helping him, he hesitated and stood frozen with fear while the spirit got away with his brother. Now Tarou is on a quest to find his brother and exterminate evil spirits.
