Meet Keitaro Urashima, a 19-year-old boy who is useless at study and pathetic at sports. He has never even had a girlfriend. But 15 years ago, he promised a girl that they would study together at Tokyo University. After failing the college entrance exams 3 times, his parents kick him out. The story starts when Keitaro visits the Hinata Inn, which is run by his grandmother. But the inn has become a dormitory for girls and grandmother is away overseas. Keitaro is made the dormitory superintendent, even though his clumsy and erotic mistakes earn him a reputation as a pervert. The boarders are all beautiful girls with strong personalities. Naru Narusegawa is very smart and ranks number one in the nationwide preliminary entrance exams. Shinobu Maehara is shy but good at housework. Kaolla Su is a lively (but dangerous?) and mysterious foreigner. Motoko Aoyama is handy with a sword, and Mitsune Konno is a freelancer who loves boozing and gambling. And so Keitaro starts as the superintendent, although all the boarders are dead against it. A mild erotic love comedy about a boy studying for the Tokyo University entrance exams.
