Thirteen years ago, the Villainous Army of Evil attempted to invade Earth, faced by theSuper Sentai squadron known as the DivineDragon Rangers (竜神戦隊ドラゴンキーパー,Ryūjin Sentai Doragon Kīpā;lit. 'Dragon God Squadron Dragon Keeper'), 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.
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.
The "Colorless" refer to the lowest-ranking members of the Keeper hierarchy, and are often looked down upon by those higher up the ranks.

A flying fortress appears over the town as a group of heroes called the Dragon Keepers dedicate themselves to defend humanity in a never ending war against the invaders. Thirteen years later, the fortress continues to send down monsters and creatures called Dusters to fight the Dragon Keepers every Sunday in an arena display called the Sunday Showdown. The latest is Ul-Tora Tiger, who puts up a dramatic fight against the Dragon Keepers before being defeated. However, it is revealed that this was all staged. In reality, the Dragon Keepers beat the invaders within the first year they arrived. They set up a truce with the remaining Dusters to have them put on performances like this in exchange for being allowed to live. One of the Dusters, Footsoldier D, has grown tired of this and tries to take a stand against the Dragon Keepers before being swiftly cut down by the Red Keeper. He decides to disguise himself as a human and join the Dragon Keepers so he can take them down from within. | |||||||

Meanwhile, Red and Blue Keeper arrive at the fortress to punish D and scare the Dusters back in line. D plans to stab Red Keeper when he sees him but is scared off by the garrison members and Red Keeper himself. After leaving, Suzukiri reveals she knew about the knife and who D really is. She tells D she wants to work with him to kill the Keepers. Just then, the real Sakurama shows up and says a monster has appeared nearby. The monster is D's friend Footsoldier F, who is trying to find D to bring him back. Red Keeper himself shows up and uses the Divine Artifact to truly kill F. | |||||||

Meanwhile, D is revealed to be alive but now has a stomach wound that will not heal thanks to Blue's Divine Artifact. He is found by Sukurama, who tells D his backstory. They are then found by Hikeru. Sukurama tries to lure him away but after Hikeru threatens him, D arrives to fight. Hikeru counters with a Divine Artifact replica that D cannot touch due to it only being able to be used by someone Hikeru "bonds" with. D runs away and tries to use Sukurama as a hostage. Hikeru backs off and drops the replica. Sukurama grabs it and appears to kill D. In reality, the two made an agreement to swap disguises so D could infiltrate the Rangers.
