Story
Mugen is a rough-around-the-edges mercenary with a killer technique and nothing left to lose. Jin is a disciplined samurai who's as deadly as he is reserved. Fuu is a young waitress with a good heart and a resourcefulness that emerges when you least expect it. These three unlikely companions are about to begin a journey that will change all of their lives. It's a dangerous quest for a mysterious samurai that will see our squabbling group of heroes get into and out of trouble more times than they can count (which admittedly, isn't very high).
