Absolute Anime

Hello!
I know there is an episode in the anime in which Sano and Katsu fights a gang which are using the name of the Sekihoutae... but i can't find it! what's the name/number of the episode???

I haven't watched that much of this anime to be honest and what I have watched is when it was on the Sci-Fi channel dubbed as Samurai X.

But I have heard people talk about it... I'd say try and search again for it spelling it: Sekihoutai or Sekihōtai ;]

Or just hang around until someone with greater knowledge replies. x3
