Plot
Thirteen years ago, the Villainous Army of Evil attempted to invade Earth, faced by the Super Sentai squadron known as the Divine Dragon Rangers (竜神戦隊ドラゴンキーパー), also known as the Dragon Keepers, and their super weapons, the Divine Tools. The evil army, however, was defeated within a year, all of its Executives wiped out, and the surviving (and almost immortal) foot soldiers have been forced ever since to reenact their defeat to the Keepers in front of a crowd of spectators every Sunday. Tired of the charade, and realizing that this amounts to little more than slavery, one of the foot soldiers rebels, and decides he will defeat the Dragon Keepers by infiltrating the organization.

Dragon Keepers


The Dragon Keepers organization comprises the five "First Class" Dragon Keepers and those under their command. Each Keeper has their own battalion with distinct responsibilities within the organization, and each member has a different rank determined by their respective Keeper. The First Class Keepers also possess the Divine Tools that have the power to permanently kill members of the Villainous Army, although lower-ranking members can be assigned replicas or other weapons with similar power.
