The protagonist of the series is the lecherous Satonaka Ikkou, who transforms into a super-monk (being able to perform mass exorcisms) by his lust for the girls he lives with. He lives in the Saienji Buddhist Temple as a Buddhist priest-in-training together with six other nuns: Amanogawa Haruka, Ikuina Sumi, sisters Sugai Sakura & Hinata, Nambu Chitose and Atouda Yuuko, each of whom represent one of the bosatsu of the six lower realms of the traditional Buddhist cosmology. Chitose is the other main character and has a strange relationship with Ikkou; he seems to be in all the wrong places at all the wrong times, but they really care for each other in all actuality. A side effect of Ikkou using his ultimate power is that immediately afterwards, he turns into an even bigger pervert than he normally is. The series is about Ikkou's self-destructive power and his attempts to control it.
