Seven schools are competing for complete control over the region of Kanto. The students are known as "Fighters", and each carry a sacred bead, or Magatama, and enclosed in it is a spirit of an ancient fighter from 1800 years ago in Chinese history. The Fighters are destined to the fates of their Magatama. Enter Hakufu Sonsaku, a big-breasted, air-headed bimbo, who joins the ranks of Nanjou Academy, alongside her cousin, Koukin. Encassed in her Magatama is the spirit of a fierce warrior who conquered the lands 1800 years previous, but was killed at an early age. The Big Four of Nanyou Academy see her as a threat and wish to prevent history from repeating itself.

Fighters from Rakuyo High School have been found hanging around near Nanyou Academy. Rakuyo is headed by the fierce Fighter Totaku, who has conquered a couple of the schools in Kanto. Other schools have been banding together against him. Meanwhile, while running late for school, Koukin reveals to Hakufu that he would be willing to sacrifice himself if it meant protecting her. Gakushu questions Saji over Nanyou Academy's leader, Enjyutsu, whom he has not seen in months. Gakushu feels that there is something going on that he has been kept in the dark about. Enjyutsu sees Hakufu as a threat and issues the order to Big Four member Kannei to execute her to prevent her destiny from being fulfilled. This order is given to the whole of Nanyou Academy, and results in Hakufu doing battle with Kannei and Ryomou, while Koukin fights all of the students and Saji. Will they all survive? And what is Saji planning?
