Hakufu Sonsaku joins the ranks of Nanyo Academy with her cousin Koukin. Inside her Spirit pendant is a fierce warrior who conquered the lands 1800 years ago. The Big Four of Nanyo Academy see her as a threat and wish to take her out.

The fierce Fighter Totaku of Rakuyo High School has been conquering multiple schools in Kanto. Other schools have been banding together against him. Meanwhile, Hakufu ends up battling with Kannei and Ryomou, while Koukin fights a mass of students on his own.

Hakufu defeats Ryomou through a force taking over her body, almost leading to Ryomou's death. Koukin vows to protect Hakufu so that it never happens again, but Hakufu runs away from home, only to end up in trouble.

Taishiji is given an order to execute Hakufu.

The Great Fighter's Tournament is approaching. Totaku, the previous victor, has rigged the draw for the tournament. Hakufu goes on a rampage to avenge Taishiji and is overcome by her spirit 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.

A mother-daughter rivalry rears its nasty head when Hakufu tangles with Kakouton, and the ranks of Rakuyou High School are diminished by a sudden uprising.

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.

Chuubo reveals her shocking true identity before joining Koukin and Hakufu on a mission to rescue Ryomou!

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.
