Ririko Kagome is a teacher at Yōkai Academy, specializing in mathematics. Like Tamao due to Tsukune Aono's scent, she is in love with him. Seemingly innocent and deeply concerned for her students' grades, she offers private lessons to anyone willing, though at a price. Kurumu Kurono has stated that Ms. Ririko is a "little weird". According to her, Ms. Ririko's really passionate about teaching but has a one-track mind. This causes her to "go overboard with everything" which may explain her after-school tutoring sessions.
