Its from the same people who made Cowboy Bebop. I just saw the first 17 eps.
Here's a summary i found on the old internet:
Mugen is a fierce animal-like warrior with a unique Bboying (break-dance) inspired fighting style. Jin has a more traditional style but don?t think of this as a weakness because his skills are amazing. The two contrasting samurai warriors are far from friends, yet their separate paths seem to cross anyways. Mugen is wandering aimlessly through the city when he stumbles upon a teahouse where he meets Jin and Fuu (A ditzy waitress, but don?t think she doesn?t have anything hidden up her sleeves). Fuu convinces them both to come with her in search of a mysterious samurai that smells like sunflowers and their journey begins. This modernized hip-hop tale breaks the barriers of the common, historical, samurai anime.
