Muramasa wanted to be the best swordsmith and made a demonic sword which grants insane powers. But things didn't turn out as he wanted and he leaved the town. Now he's back with his legendary forbidden weapon that drains the blood out of its enemies and also its wielder. To satisfy the sword's thirst, you must slay your enemies and collect soul points so you can purchase great upgrades.
