For a hundred years blighted by obscurity, the populace endured immense suffering under the tyrannical reign of Vandel - a rascal whose monstrous army obeyed his every command. The Vandel Busters, a group determined to rid the world of these despicable fiends, housed the renowned Zenon Squad. Renowned as the most skilled and accomplished busters on the continent, they were held in high regard. Beet, a young lad, aspired to join their ranks. Alas, his inadvertent involvement in the Zenon Squad's downfall at the hands of the devil Beltose was the cause of their demise. The five dying busters merged their Saiga weapons with their life force and entrusted them to Beet before passing away. Many moons later, Beet has become a young Vandel Buster and embarks on a mission to preserve the legacy left by the Zenon Squad by bringing an end to the century of darkness.
