The hapless, somewhat bruised-and-battered main character of the story. Because of a promise he recalls making to a childhood
sweetheart 15 years ago, Keitaro's been trying to get into Tokyo University (for the record, Tokyo University is the premier
college in the country. It's
very tough to get in, and you can only try once a year). But bad study habits and low
self-esteem have contributed to two failed attempts.
He jumps on the opportunity to get away from home and come back to the home of his youth: the Hinata Apartments.
Thing was, he didn't realize that the place had turned into a girl's dormitory, and it takes a while for things to settle
down, though they never completely settle down even as he moves into Room 305 (directly below Naru, who's in 304). Though Keitaro does sometimes have those male kinds of fantasies (he's surrounded by pretty girls, and
there's a hole to Naru's room in the ceiling), his frequent episodes of pervertedness are typically accidental: usually the
result of clumsiness or just bad timing.
Overall, Keitaro's just trying to get things straight in his life. He's nice enough if you can just forgive
his (usually accidental) slights, though he still has to get over his down-in-the-dumps attitude. He also has quite a talent
for art.
