In Onechanbara™: Bikini Samurai Squad™, Aya, a descendent of the family known as Imichi, meaning blood that goes out of control, reconciles with her sister Saki and live together in peace for awhile. The peace doesn't last for long as an infestation of zombies has plagued the city. The sisters join together to draw their swords and rid the city of evil.

Play with a friend in co-op mode or switch between any of the three beautiful playable characters in single-player. Each character has a variety of unique moves to master during combat to destroy enemy zombies. Get blood on either sister to trigger Rage Mode and gain more power and agility to destroy enemies faster and deadlier. For an added experience, go to Marketplace to download additional outfits and sword-flinging girls.
