After Tomoe's death, Himura Kenshin became a free wielding swordsman. Makoto Shishio became his successor as hitokiri (assassin). Later, the new Meiji government believed it would be best to eliminate Shishio. Thus, Shishio was knocked out from a blow to the head, doused in oil and burned alive. He survived, sustaining severe damage to his entire body. He now seeks revenge by burning Tokyo like they burned him.
