Keiichi Kanejou

Kanejou's brother, who came from America (probably Harvard University). He is the object of every woman's infatuation, even a princess from a foreign country could not withstand his "charm". He later returns, but has seemingly gained an interest in Yamada, much to Kyoka's chagrin, this most likely because she is so far the only woman that has not instantly fawned over him. He reveals he is a virgin, though unaware of the fact his sister uses her power to do so. At the end of the anime, he wished to lose his virginity to Yamada.
