Anime Profile: Maken-ki! Battling Venus

Tenbi Academy is not your average Japanese high school. The students there practice magical energies called Elements, as well as weapons known as Makens, and as such participate in sanctioned duels with each other to master these. It WAS originally an ALL-GIRLS school, but this year was converted to a co-ed format, so now the school has its first male students.

Takeru Oyama, a sweet but perverted boy who had suffered through an all-boys junior high, is more than delighted now that he is in this school filled with beautiful girls. He is also reunited with an old friend of his, the buxom, yet earnest Haruko Ayama. However, it isn't long before two other girls take notice of him – Kodama Himegami, a popular student who, for some strange reason, wants to kill him. The other, Inaho Kushiya, a sweet girl who claims to be Takeru's fiancee! And there's still the busty Haruko, who wishes to protect her friend from these unwanted intruders. In time, it is discovered that Takeru possesses special abilities of his own... something that may come in handy when the dark secret of Tenbi Academy is discovered!
