Jyotoku Kawahara commands authority as the head nun of Saienji Temple, rigorously training its residents, including her grandson Ikkou Satonaka. She enforces strict discipline through demanding chores and responsibilities, often chastising Ikkou for his perceived laziness and lax adherence to Buddhist doctrine. Her leadership encompasses overseeing the temple’s exorcism operations and mentoring six female trainees under her charge.

Elderly in appearance, Kawahara’s closed eyes and prominent eyebrows frame a stern visage accentuated by her habitual smoking. Her demeanor radiates the seasoned resolve of a spiritual mentor, unwavering in her no-nonsense approach to cultivating her disciples’ exorcism prowess and spiritual discipline. Though her history beyond temple leadership remains unelaborated, her actions prioritize honing her charges’ abilities through relentless guidance and structured rigor.
