However, this seems to be impossible because of the fact that he is constantly bullied by his delinquent classmates. When Rokudo and his friends become desperate, Rokudo receives a mysterious package from his long-deceased grandfather. Inside lies a priest's uniform and a mysterious scroll passed down through his family since the Heian period, said to hold a technique that wards off demons and evil spirits.
