Height: ? I dunno...short, though.
Keiichi is the main character next to Belldandy. He dialed the wrong number and reached "The Goddess Relief Office." He basically wished for Belldandy to be with him forever, and that's what he got, along with her two slightly annoying sisters.
Keiichi is a short, shy, understanding and gentle guy, who's intentions are pure and he always tries his best. Of course, you should figure out that he falls in love with Belldandy. ^_^ Nevertheless, he still seems to be a lady's man, even though he has Belldandy (Peorth, for example, likes him).
