Anime about a guy who changes the lives of several girls, it's also one of those animes that are better than the manga.
By the way, there's small nudity (Nipples for 5 seconds) and adult themes, so don't go blaming me for introducing you to hentai.
Each episode goes through this thing where Kintaro finds a temporary job and finds a girl, and in the very end of the episode he changes her life in a positive way; he looks like a dumbass weakling who's nice, but he's actually a genius who could beat a black belt to a pulp.

Oh, hey here's this chick riding a motorcycle.
