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).
