 A boy known as Musashi, reincarnated from the legendary Brave Fencer Musashi who saved the Allucaneet Kingdom from a monster called the Wizard of Darkness 150 years before, is summoned to Allucaneet by its ruler Princess Fillet to save it from the invading Thirstquencher Empire. Musashi is given the blade Fusion, and is charged with the task of obtaining Brave Fencer Musashi's sword — Lumina, the Sword of Luminescence — before the Thirstquencher Army does. Although Musashi has no intention of saving the kingdom, he agrees to do so in order to return to his homeland. After Musashi recovers Lumina, he finds that most of the people from the Allucaneet kingdom, including Fillet, have been kidnapped by the Thirstquencher Empire. In order to rescue all the residents from Allucaneet and defeat the Empire, Musashi starts searching for the Five Scrolls; each one holding an elemental power able to greatly augment the sword Lumina's powers.
