Sanosuke, world health organization has a assumed name "Zanza", is the go of the Sekihōtai, world health organization fought in a imperial alliance at the prevent of the Tokugawa regime. Sanosuke ab initio wore the hate for tons previous Imperialists. A understanding that he is the previous of the Sekihōtai is because his captain, Sagara, & his followers, were executed per Meiji law for impersonating a royal army & spreading treacherously allegations all about moo rice numbers. This setup was engineered by Shindō Tatewake, the previous officer in the regal alliance.

, but when existence discomfited per previous assassin & learning of Kenshin's there is no-stamp out approach, Sanosuke becomes the worthful ally. He late adopts the boxing-rather fighting skill. When you took a Shishio crisis, Sanosuke learns 'Futae there is no Kiwami' (Double Level Limit) from either the previous monk, Anji there is no Ourō'ō. Futae there is no Kiwami occurs as favorite art, whereby a assaulter utilizes deuce clock on quickly succession; a 1st punch neutralizes a hardness of a target, so a 2nd breaks a target prior to it recovers from either the click of the foremost blow. Late, inside the fight against Anji, Sanosuke's desperation leads to the discovery of the third level, where he strikes using the Futae there is no Kiwami sustaining both of his 5 fingers.

Sagara Sanosuke begins in a series as a moderately frail character, just capable of defeating the moo stratified foes like Beshimi, Hyottoko, & Shikijo of the Oniwabanshu. He never really contributes to the major foes like Aoshi & Udo Jin-E. In a period of the Kyoto arc; notwithstanding, he learns Anji's 'Futae there is no Kiwami' & is taken further seriously as a threat. Makoto Shishio comments how else he is "no mere tagalong" & possibly Saito begins to acknowledge his skills (though he however considers him an cretin). At this point he might not stand a risk against a major villains (except Raijuta world health organization is believed by a select few that Sanosuke could have defeated when you took the Tokyo arc), however he potty kill stronger minor villains.

A symbol on the back of Sanosuke's jacket is the Japanese kanji Aku, which means "evil". He bears this symbol as a mark of his loyalty towards his past in the Sehiko Army.

His Japanese seiyū is Yuji Ueda and his English voice actor is Lex Lang.
