One day, it was predicted by spies that the princess was endangered by an assassination attempt by Oboro. As she bore a striking resemblance to the princess, Karen volunteered herself to be the decoy princess to lure Oboro in. In spite of Jushiro's protests, the coup was staged. Oboro attacked but his strength was overwhelming and he preceded to kill everyone at the site, including the "princess" Karen. Jushiro, who arrived at the scene too late to assist, was targeted as the main suspect of the massacre by the bakufu, earning his disgust and desertion of his samurai class. Since he was a member of the secret service who knew several critical secrets, the government ordered for his elimination.
He escapes from his pursuers to Ritenkyo where he joins with female warriors Saya and Rinka to form the "Atom Rebels", an anti-Bakufu group. Once he learns that Oboro was in Ritenkyo, he sets out to slay him. In his ending, he defeats Jin-Emon in a duel and spares his life.
