Synopsis Sentai Daishikkaku
Thirteen years of endless battles between the "vigilantes" of the dragon keepers and the invaders of the monster armada have kept the earth in a constant, never-ending war. Which attracts many spectators in a battle every weekend. Where they are always fighting the dragon keepers with a villain who commands the forces of the dusters, low-ranking but immortal soldiers who have been defeated every week for 13 years.
13 years of well-programmed war
The story tells us that they fight every weekend, something that is really irrational in a war, why would you have a calendar to attack?. And that's exactly what we see when we start to learn a little more about the story from the side of the "villains" where we find out that they are just Dusters who remain in the floating fortress.
The argument shows us villains who, no matter how immortal they are, only know how to be simple villains to "fight" against the Dragon keepers every week. These villains are nothing more than a forgery of a boss and invent one weekly to survive.

The agreement of the dragon keepers in Sentai Daishikkaku
Yes, it turns out that they have an agreement with the dusters not to eliminate them so that they can continue their weekly battles. Since the floating fortress fell only a year after arriving on Earth and from that moment they eliminated all the bosses that the dusters had, leaving only them. Simple foot soldiers without strength or power.
We have D as the protagonist, another duster of the bunch who is more than tired of his life for these last 13 years of defeats. He decides to rebel against the dragon keepers in their weekly battle and escape from the floating castle. But not before trying to defeat them alone in the way he knew, but which was not entirely clear if it would work.
Characters Sentai Daishikkaku
Duster D or Invader D
A duster with enough courage to rebel after 13 years against those who have kept them repressed, despite his little strength. The truth is he's not the smartest, nor the strongest but one capable of making transformations that others would find impossible and with a unique luck for getting out of problems at the last minute taking what would almost always be the most drastic path.
The fact of being immortal gives them some advantages to make attacks that others would consider simply suicide. But which is all the same to them because their regeneration capacity is enormous.

Dragon Keepers
The heroes of all humanity or at least that's what they appear to be are 5 rangers, Red Keeper, Green Keeper, Blue Keeper, Yellow Keeper, Pink keeper. They are what humans would consider their heroes, but not those who organized the weekly battles and did not end the villains after invading the floating fortress.
So it is doubtful if they are really the good guys in this story or just pretending to be, something that we will only know as the plot develops. Who are the dragon keepers really?.

Suzukiri Yumeko
A young woman with a somewhat faded look who not only recruits novices for the dragon keepers patrol but can see more. If beyond the disguise of the little escaped duster named D in the human world. She is strong, much stronger than she appears and for a strange reason pays a lot of attention to duster D

Opinion and expectation
A story with a dramatic twist where the protagonist is the enemy of humanity is something we have seen. But being so absolutely weak as they are dusters gives it an air of progress that really makes you want to know. Apart from how the dragons keepers ended everything in just one year is more than suspicious, why would you maintain a war for 13 years straight?.
Many intrigues and few answers in this anime that has little and much of superheroes saving the world and supporting a villain who wants to end it all. The truth is a novel argument with a touch of madness and action by the protagonist that has its charm. Come on duster D you can beat the dragon keepers I believe in you.
