Ittoki is an upstanding student in school, taking a multitude of advanced classes and even attending a cram school six times a week. He is also very physically capable, taking a gymnastics class three times per week on top of his other extracurricular activities. He is friends with Kousetsu although he finds her overbearing at times as she never lets him stray away from his schedule to have fun.

He becomes the Chief of Iga Village as the legitimate successor following Yumika's death.
