Keitaro is your average 19 year old main character.
Ok, not really. Keitaro is a very strange boy indeed.
Keitaro is trying to get into Tokyo University... for the 3rd time.
Why does he try so hard even though he already failed the entrance exam twice?
Why Tokyo U?
All this work is because of a promise he made 15 years ago to a girl he really liked.
It is said that when two lovers enter Tokyo U together, they will find great happiness.
Unfortunately, Keitaro can't even remember the name of the girl of his memories.
Yet he still strives for Toudai for her. How sweet, ne?
Through a strange chain of events, Keitaro becomes the manager of the Hinata-Sou,
an all girls dormitory.
To the girls, Keitaro is just a baka (idiot) and a hentai (pervert).
Keitaro isn't really all that bad, he is just clumsey and tends to get caught in the wrong situations in the wrong times. Poor guy.
