Rurouni Kenshin: Tsuiokuhen

Rurouni Kenshin: Tsuiokuhen is designed as a prequel to the television series, but can also be used as an introduction to the Kenshin world. Dark and deprived of any comical relief, these OVAs are certainly a big contrast compared to their television counterpart, but make for a perfect complement in terms of character background and entertainment.
This OVA series is a whole lot more than simply "how Kenshin got his scar". Its rich storyline covers every aspect of Kenshin's sinistrous past as portrayed in the original manga. The names and terminology may confuse the unfamiliar yet it's nothing a second watching can't clear up. Even though the violence at times seems excessive and takes a step back from practicality, the symbolism, historical references and frequent flashbacks put this one in the rare strain of action anime you need to concentrate to revel in.
Technically outstanding, Rurouni Kenshin: Tsuiokuhen delivers steady animation at a high frame rate in which every single cel is polished and detailed. It also displays a more solemn and down-to-earth art style than Rurouni Kenshin, which sets the mood flawlessly. Music certainly perfects the package, as well. Iwasaki Taku did an outstanding job composing and orchestrating what I have no reserve in calling one of the best original soundtracks ever made (you can hear more of Iwasaki Taku in Read or Die and Rurouni Kenshin: Seisouhen, the OVA sequel).
For people ranting over the blatant mistranslation of the Japanese title to Samurai X, the DVD includes a reversible cover allowing them to choose the traditional name. A Shakespearean drama at the finest, an ending that will leave you in shock for several days, first rate visuals and a brilliant instrumental score; what else can you ask for?
