Ikki Tousen (2003 - 2010)

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?

The schools throughout Kanto begin to form short-term alliances as a means of disposing of their enemies. Taishiji is given an order to execute Hakufu Sonsaku. After his school's Fighters render Koukin incapable to fight, Hakufu does battle with Taishiji himself. How will it all end?

The Great Fighter's Tournament is approaching quickly. Totaku, the previous victor, is hoping that the other schools will eliminate each other, leaving him to do battle with the sole, under-strengthed school left in the tournament (other than his own), and in order for ends to meet, he has rigged the draw for the tournament. Hakufu goes on a rampage to avenge Taishiji, but is defeated, until the spirit awakens within her once again...

The new Fighters Tournament has now commenced. Which school will come out on top? Will anyone defeat Toutaku? How will Nanjou Academy go with Hakufu Sonsaku fighting for them? And will the spirit living inside her be awakened once again?

Hakufu and Koukin manage to fend off the crazed snake-like Kannei Kouha. Ryofu continues to pursue her own relationships with the possibility of betraying Tontaku. Shimei Ryomou fights the beautiful but deadly schoolgirl-uniformed Kanu Unchou of Seito Private School on the rooftops. Hakufu gets in another battle as well.

Nanyou Academy gets to fight Kyoshou Academy in this round. Hakufu Sonsaku is up against Kakouton "Basic" Genjou, but Aunt Goei arrives; whom will she support? Ryomou's opponent, Kakuka Houkou isn't a pushover either. Meanwhile, Kaku Bunwa and Ryofu Housen get into a heated conflict; Ryofu Housen and Chinkyuu Koudai decide to walk away from Toutaku's gang.

Aunt Goei takes Hakufu and Koukin to a mountain hot springs that seems to attract some of the other female fighters including Ryoumou and Ryofu who are also hoping to recover. Hakufu catches up to Ryoumou and they spar with Hakufu's old teacher Choukou.

Aunt Goei gives Hakufu and Koukin some tickets to the pool. Ryoumou ponders her fate to guard Hakufu. At the pool, Toutaku catches Hakufu in an alone moment, and befriends her with some watermelon. The mysterious and foreshadowing Ukitsu appears before Goei, looking for Hakufu. Chinkyuu gets caught stealing the Gyokuji. Ukitsu arrives at the pool and challenges Hakufu to a fight. Ryofu decides to get her revenge.

Ukitsu was about to fight Hakufu, but Hakufu was weakened by Toutaku's touch, so she gives up. Goei, Ryoumou and Koukin ponder Hakufu's destiny where her dragon fighting spirit may awaken and she might lose her life. Ryoumou and Koukin look for Gakushuu. Koukin meets Saji who invites him to see the senior leader Enjutsu, but then gets ambushed and attacked. Hakufu stays home for the day, but then learns of her fate, and decides to go after Toutaku.

Toutaku forces Hakufu to battle Ryofu, otherwise Ryoumou will be killed. The girls fight each other, but also attempt to go after Toutaku. It looks like no one will be able to win, until Ryofu defies her fate, and uses her ultimate technique. Hakufu and Ryoumou learn Saji's true identity and they go to rescue Koukin and confront Saji.

Hakufu and Ryoumei go after Ouin Shishi, who manages to enrage Hakufu. But instead of her dragon spirit manifesting, Hakufu channels the remaining influence of Toutaku and gets out of control. Can Koukin save her from her fate? Ukitsu also comes back for a final challenge.
