Best fucking shonen anime/manga ever. Main protagonist is Himura Kenshin, who was the famed (if not infamous) Hitokiri Battousai during the Bakumatsu. After the revolution and a very bad event, he takes up the sakabatou and swore to never kill again and instead wandered Japan helping those who needed it in order to atone for his sins during his years spent as a shadow assassin. Story revolves around the freaks who try to prove themselves the strongest by attempting to kill Kenshin, people from his past who seek revenge against the ex-hitokiri, Kenshin's never ending quest to keeping the peace of the Meiji period with his friends, and of course, the romantic comedy that revolves between him and Kamiya Kaoru, the main female protagonist.
Best thing about this series is the amount of historical info and influence that is present throughout. Story spans through two of the most important eras of Japanese history: The late Edo(Tokugawa) Period and the early Meiji Period, and many characters were either loosely or
directly based off of real people from those eras. That, or Marvel characters says Nobuhiro Watsuki, the creator of Rurouni Kenshin. Rurouni Kenshin is basically a history lesson in comic book format. :D
Rurouni Kenshin fans have to be some of the most die-hard and most informative anime fans out there. We don't just swallow any form of Kenshin media that they give us and settle for it (Like "Rurouni Kenshin: Seisouhen", to totally melodramtic, un-canon "finale" of the Rurouni Kenshin saga), and, we actually learn more about the history and terminology of Rurouni Kenshin by reading BOOKS in our spare time.
Rurouni Kenshin is certainly an anime to behold and deserves way more recognition than some of anime that they continue to air on Adult Swim.
Rurouni Kenshin totally whoops Bleach's and Naruto's asses. Bleach and Naruto fans just can't comprehend the physics and historical data involved in Rurouni Kenshin like RK fans do.
Two things that all die-hard Kenshin fans know:
1) Himura Kenshin was not a true samurai.
2) Rurouni Kenshin: Seisouhen was shit.
