Shingo Ninomiya lives with his sister Reiko, an unrivaled master of martial arts and, at the same time, a special forces operative (the older Ninomiya siblings are now "somewhere abroad," and the son is confident that his parents are fine, even though they give no information about themselves). It"s no surprise that Shingo grows up continuously refining his body and will. And now, at last, he will need the results of his training: Reiko, having bargained with the succubus family, arranged that her brother would take under his care the young Mayu Tsukimura—a succubus with a powerful aura of attraction and extreme androphobia (fear of men). Thus, Ninomiya-kun became a bodyguard, governor, and sex therapist for the shy yet irresistibly attractive Mayu. And this greatly displeased Rēke Hodzyu, the president of the school council—a despotic little heiress.
