Rebirth of Mothra III

The Elias sisters, Moll and Lora, attempt to stop their vengeful sister, Belvera from seeking the secret power of the Elias Triangle, three power units that can transform the sisters' daggers into powerful swords. Belvera succeeds, but she is thwarted by her sisters' pet, Fairy Mothra, and fails to retrieve the proper unit for her dagger while Moll and Lora end up with one for the former.
