Head Monk of the Temple that the group resides in, grandmother to Ikkou, and Assistant Principal to the High School that the group attends. She is extremely strict to Ikkou more than anyone, though this is primarily because she believes him to be spoiled and lazy and does not train hard enough to keep himself from awakening. There have been occasions in the early part of the series where she has let an awakening or another infringement of temple policy go by unpunished, but by the end of the second season she seems to think she might have been too lax with him. She is generally firm with the nuns as well as Ikkou, though Ikkou seems to be the one most frequently in a position to be punished. She, like the other characters, strikes Ikkou repeatedly without remorse but she uses her staff. There seems to be some indication that in her youth Jotoku was a beauty (not only she claims this, but all the older monks around her still seem to think of her as attractive). In the brief points where she is portrayed young, we do not see her face, but she has long hair and even seems to be taller (probably a gag).

Satonaka Ikkou, a 16 year old boy, is a first year trainee at the Saienji Buddhist Temple. He was sent there by his parents to be trained by his grandmother, the Saienji Priestess. At the temple he finds himself surrounded by beautiful female priestesses-in-training. Upon seeing a girl naked, Ikko has the ability to turn into a super-monk, performing massive exorcisms for the good of the temple.

A behind the scenes special of all the main characters in Amaenaide yo!! Katsu!! Where they give there own personal feelings about their past experiences with the show as well as their working experiences with their fellow cast members.

Ikko and the girls of Saienji Buddhist Temple are participating in a game show competition and happen to win a trip to a secluded inn. At the inn, Ikko is presented with the challenge of not awakening while all of the girls are sleepwalking.

The protagonist of the series is the lecherous Ikko Satonaka, 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 Temple as a Buddhist priest in training with six other nuns: Haruka Amanogawa, Sumi Ikuina, Hinata and Sakura Sugai, Chitose Nanbu and Yuuko Atouda, each of whom represents one of the bosatsu of the six lower realms of the traditional Buddhist cosmology. 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 subject matter of the series is Ikkou's self-destructive power and the powers of the other nuns and their training to control these powers, as well as their (mostly non-romantic) relationships.

Realizing his immaturity at the memorial service for the previous Holy Shonin, Ikko returns to the main temple for further ascetic practice. Six months have passed since then, and Haruka, Hinami, Yuko, Yo, and Chitose, with Sakura as the new head priest at Saienji, have been spending their days in contemplaton, doing manual labor and practicing their exorcisms. Then, around the time of the cherry blossom season, Saienji was approached to help perform an exorcism of an old cherry blossom tree.
