The Vandel Busters are a group dedicated to hunting these devils, and among them, the Zenon Squad is renowned for its strength across the continent. A youthful individual named Beet aspires to join this elite squad. However, due to his error, the Zenon team suffers a devastating defeat at the hands of Beltose, the devil. The five dying busters transfer their life energy into their weapons, Saiga, before passing away.
