jinchuu story arc which was found in the manga only.
i'm not wrong by a long shot , seisouhen was a tame interpretation of that final arc. It didnt show when Kenshin and Enishi fought for the first time and Kenshin got his ass handed to him ( Enishi countered the Hirameki). It didnt show when Enishi \"killed\" Kaoru and added insult to ass whipping on Kenshin's part. It didnt show Aoshi for the true badass he is ( yes he is badder than Saito) and lastly Keshin DID NOT DIE IN THE MANGA
