When government officials start getting murdered by an assassin called Kurogasa, Kenshin is asked to protect a certain government official. Sano, never one to miss a fight, goes with Kenshin. ''After seeing the assassin, Kenshin realizes that the assassin is Udou Jine, an outcast of the Shinsengumi. Jine was cast out from the Shinsengumi because he killed people for pleasure, not for the Shinsengumi cause. When Jine finds Kenshin, he realizes he has found someone who he can enjoy fighting against. He tells Kenshin to go back to being a Hitokiri (assassin) because if Kenshin doesn't, he will never be able to beat Jine, and Jine will keep killing people. ''Jine kidnaps Kaoru, hoping this will speed up the process of Kenshin becoming a Hitokiri once more. ''moreless

Jinei has captured Ms. Kamiya, and now Himura must stop him at any means necessary. Himura shouts out his final cry, "Jinei!!!"moreless
Jinei was never called the Battousai in this episode, rather he was known as a stray Manslayer.
Edit
Actually the term "Manslayer" was not cartoon network's idea but Anime Works.
Edit
Jin-e is not a "battosai", but a hitokiri, which means assassin in Japanese, or as Cartoon Network puts it, "man slayer".
Battosai is the nickname given to Kenshin because he has mastered all aspects of the battoujutsu techniques, that of starting the sword in the sheath to increase the speed of the attack.
Edit
Nobuhiro Watsuki was supposedly reading American comics at the time he created Rurouni Kenshin, particularly the X-men and Spawn. This can vaguely be seen in the fact that Jinei's headgear is quite similar to Gambit's in the X-men.
Edit
Jinei Udoh was originally based on one of the four real hitokiris in the Bakumatsu era, named Okada Izô, although the author admits that Jinei ended up nothing like Izô.
