The protagonist of the series is the lecherous Ikkou Satonaka, who transforms into a super-monk (being able to perform mass exorcisms) by his lust for the girls he lives with (Note: In the anime, he transforms from seeing a naked girl). He lives in the Saienji Temple as a Buddhist priest in training with six other nuns: Haruka Amanogawa, Sumi Ikuina, Hinata and Sakura Sugai, Chitose Nambu and Yuuko Atouda, each of whom represents one of the bosatsu of the six lower realms of the traditional Buddhist cosmology.
