As a first-year trainee at the Saienji Buddhist Temple, 16-year-old Satonaka Ikkou is receiving instruction from his grandmother, the Saienji Priestess, as per his parents' wishes. However, his training is complicated by the presence of several beautiful priestesses-in-training at the temple. Whenever he glimpses one of them naked, Ikkou's hidden powers are unleashed, transforming him into a super-monk capable of conducting massive exorcisms to benefit the temple.
