With Toutaku Chuuei's defeat behind them, the academies of the Kanto region settle into a rare stretch of peace, and Hakufu Sonsaku spends her days scraping together money for upcoming fighting tournaments alongside Koukin and Ryomou. The calm breaks when a girl named Sonken Chuubou turns up claiming to be Hakufu's long-lost younger sister, and Ryofu Housen, believed dead, is seen brawling in the streets again. This third Ikki Tousen season runs an original storyline rather than adapting the manga.
