In Hokke-kyo (Saddharmapundariika-sutra or the Lotus Sutra), Kishimojin, together with Jurasetsunyo (ten female rakshasas or ten demonesses), swears to guard the believers of Hokke-kyo and to punish the people who prevent 'guzu' (or 'gutsu,' the spread) of the beliefs in Hokke-kyo.
また、法華経では十羅刹女（じゅうらせつにょ）とともに鬼子母神が、法華信奉者の擁護と法華信仰弘通を妨げる者の処罰を誓っている。
