It is around for some time (2004-2005) but I only began watching this Anime recently and I was very much impressed. The anime is about a group of travellers (the 2 samurai named Mugen and Jin and a girl named Fuu) roaming through Japan of the Edo period of 17/18th century. It is made by the same makers of Cowboy Bebop and this fact is reflected by the resemblance of Mugen with Spike and the overall style of the animated characters. The anime also combines the samurai theme with Rap and Funky beats. The battles are awesome and there are a lot of graphic scenes. Also its quit funny, especially Mugen and Fuu.
