Haruhi Nanao

Ash is a student at Ansalivan Dragon Academy, attended by children who have formed contracts with dragons. He possesses the "star mark," the sign of a contract, but since his partner hasn't been born yet, he seems insignificant. The awakening of the dragon he's raising inside his body is triggered by an incident, and it emerges in the form of a young girl.

In this story, the world is in chaos, thanks to Washu. Now in order to save it, Tenchi Masaki must go undercover as a student teacher at an all-girls school. Unfortunately for him, trouble always comes his way as he has a hard time to deal with the hijinks of his new students.

Hatanaka Ikko, a 16 year old boy, is a first year trainee at the Saienji Buddhist Temple. He was sent there by his parents to be trained by his grandmother, the Saienji Priestess. At the temple he finds himself surrounded by beautiful female priestesses-in-training. Upon seeing a girl naked, Ikko has the ability to turn into a super-monk, performing massive exorcisms for the good of the temple.

The plot begins with Souichiro Nagi and his friend Bob Makihara going to their first day of high school at Toudou Academy. They had intended to rule the school by beating up anybody that got in their way, as they had done at their previous schools. They soon learn that Todo is no ordinary high school, but rather a school that was founded to teach and integrate different fighting styles. Its students are skilled in the various arts of combat with some students possessing supernatural abilities, such as pyrokinesis, precognition, and superhuman strength based on the abilities to use their "spirit" or "ki" in Japanese.

Seven schools are constantly at war with each other, and the students within - both male and female - have become skilled fighters and constantly battle with rival schools. Their lives and fates are guided by strange jewels that contain the spirits and destinies of warriors from the Sangokushi period. One girl, Sonsaku Hakufu, has recently moved to Japan and is apparently destined to unite the schools as her counterpart united seven countries long ago. But, like all heroes, there is a darker side to her fate, and as always there is a constant struggle by those around her to break the chains of their own destinies and make their own lives.
