Details from http://girlsbravo.wikia.com/wiki/Kazuharu_Fukuyama
Kazuharu Fukuyama (referred by almost all the characters simply as Fukuyama) is a character in the Anime and Manga series Girls Bravo. He is one of the series' main characters and commonly acts as a de facto antagonist, since several episodes involve Yukinari, Miharu and Kirie trying to overcome the plots that Fukuyama sets up to get something out of them (most commonly sexual favor from Kirie).
He is considerably perverted and goes to great extent and great expense to get close and do perverted things to Miharu and Kirie, particularly the latter. He has been known to organize catfight tournaments, using black magic and several other schemes to get to see Kirie nude, only succeeding once in a plot involving a complex board game tournament, which resulted in Kirie losing and having to give him a sponge bath with her breasts. he has a deep obsession with Kirie's breasts, to the point that he keeps a shrine to them in his closet.
Character is error.
