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?

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 ...

When i started with this one i was too tired of watching mecha and school stuff which i can never get enough of.
