The evil Kanryuu was forcing Dr. Megumi Takani to make opium against her will. When she refuses to cooperate and takes refuge in the Kamiya Dojo, Kanryuu sends his elite team of ninja guards known as the Oniwabanshuu to recover the renegade doctor and punish those that interfere with the operation. Not wanting to bring their wrath upon her protectors, Megumi returns to Kanryuu.

Now, Kenshin must act if he is to keep his promise to protect her. Kenshin and Sanosuke lead the rescue mission to Kanryuu's mansion. The obstacles in Kanryuu's mansion are fierce. Even if Kenshin and Sanosuke can defeat all of the Oniwabanshuu, they will still have to face the Oniwabanshuu's dreaded leader, Aoshi Shinomori.

His sword is fast, his Kempo is invincible. Can Kenshin's reverse blade defeat Aoshi's short sword? Can Sanosuke bring himself to rescue the maker of the drug that killed his friend? Even if they can overcome obstacles from outside and from within, Kanryuu awaits...
