The Jinchuu or Revenge Arc of Rurouni Kenshin only appears in the manga. It was never animated for the anime series, although parts of it are rumored to be animated for the second part of the Seisou Hen and the back story of this arc was animated in the Tsuioku Hen. In this arc Kenshin's bloody past as the Hitokiri Battousai comes back to haunt him the person of Yukishiro Enishi, his brother-in-law, who arrives in Tokyo to seek revenge against Kenshin for the death of his sister Tomoe. Kenshin's friends are all drawn into this battle as Enishi targets anyone who has ever associated with Kenshin, no matter in what compacity that association is. Enishi's intent is not to kill Kenshin, but rather to make him suffer a living hell by making him believe he has lost the one person in his life that matters most to him.
