In the final years of the Bakumatsu, wandering mercenary Yojiro Akizuki travels the length and breadth of Japan. And while he employs his sword in the usual fashion, he also uses it to help him locate supernatural items which he pursues with single-minded determination, often with bloody results. In the course of his quest, he crosses paths with a traveling theater group whose members have their own dark agenda. Is it a chance meeting or the result of some, as yet, undiscovered conspiracy?

I think it's important to firstly note that this anime is heavily influenced by Japan's history.
It is a re-telling of what Japan went through in the final years of the Edo period, when the Samurai, Ronins, Citizens, and Military forces from Japan and foreign countries, fought for control of the country. The interesting battles and real-life tales of betrayal and backstabbing, are retold with a hint of the supernatural element, which although seemingly far fetched, does hold more than a hint of realism. The story is fascinating, but if the viewer is not into the history genre and does not care about sitting through, read more

Although I haven\'t seen much of this anime, I feel I have to express myself about it, so I\'ll make this short. The story itself is certainly a refreshing change of pace from other anime which either ignore placing fantasy elements, or go overboard and spin a wild tale of youkai and miko. The art style is definitely top notch for a modern anime, especially taking into account it is not an OVA. As for the character development, I\'ve seen about 10 episodes or so, and I find the character development quite lacking, the main character simply meets up with the others and they quickly read more

When i started with this one i was too tired of watching mecha and school stuff which i can never get enough of. I thought that this was going to be an anime that i'd rather get out of my way before going back to where i was. But the show like all anime builds up on you. I remember being so intrigued at one point that i took a day off work to finish the series.

The ending in particular was a satisfying one...mostly that is. The songs were really catchy...in fact i still find myself humming them quite often. The only thing i hated read more

Its nice to watch a historical series once in a while, you'll learn a lot on this kinds of shows. Its really interesting how they incorporate fiction along these historical events that which occured in Japan. And for me, who doesn't really know what took place on Japan, I really enjoyed Bakumatsu as an history lesson and an anime series as well. Well I'm not entirely sure though if the series is accurate, I'll look into it later.

As for the story goes, the Lord's head came from a rebel who rebelled against the king of Qin dynasty(in china of course) it was approximately 2004(correct me read more

Anime: Rurouni Kenshin: Meiji Kenkaku Romantan
Both involves the Tokugama shogunate (Bakumatsu Kikansetsu Irohahoheto is set on the final years of the Tokugawa Era while Rurouni Kenshin is set during the beginning stages of the Meiji Era). Both have wandering samurais as protagonists who later settle down with some companion. Both of them have female love interests who are also skilled in swordsmanship. And both animes have real life historical figures (Hajime Saito for RK, Hijikata Toshizo and Okita Souji for BKI who are all part of the Shinsengumi) which the protagonists are acquainted to.

Both series re-tell, real events in the history of different countries (Japan for Bakumatsu, and France for Le Chevalier) with the addition of supernatural elements. They both focus on a supernatural power, which is symbolic of the power struggle undertaken by individuals in the past, to secure their country.
