''Go, Go, Loser Ranger!'' (''Sentai Dai Shikkaku'' / 戦隊大失格, literally "Sentai Disqualification" or "Ranger Reject") is a manga series by Negi Haruba (''Manga/TheQuintessentialQuintuplets''), serialized in ''Weekly Magazine/ShonenMagazine'' from February 2021.

Thirteen years ago, the {{immortal}} ''Evil Army Kaijin'' attempted an AlienInvasion on Earth, only to be shortly thwarted by the ''Ryujin[[note]]Dragon God[[/note]] {{Sentai}} Dragon Keeper'' and their [[WeaksauceWeakness Divine Weapons]] within a year. All of their commanders were eradicated, and their {{mooks}}, the Dusters, were eventually forced into a ceasefire agreement: The Keepers would stage weekly live battles on Sundays, where the Dusters are forced to be their {{butt monkey}}s and [[StagedShooting purposely lose to them every week]] in exchange for their lives being spared. Thirteen years of this have passed, and one Duster, [[OneLetterName D]], decided he's had enough of this farce. Using a HumanDisguise, he plots to eliminate the Keepers from the inside through enlisting in their recruitment programme, but soon learns that he isn't the only person with the same plan in mind, and realises he may have gotten way too in over his head.
----

!!''Go, Go, Loser Ranger!'' provides examples of:
* ActuallyIAmHim: Chapter 2 has D seeking out Red Keeper amongst a group of his apprentices. One of them, Shun Tokita, declares himself as the Keeper, only for Yumeko to promtly out him as just a third-rate apprentice (even though Shun insists it's only a matter of time).
* AllPartOfTheShow: Inverted. The public and ''most of the Rangers'' are convinced the weekly confrontation with the Kaijins is an actual BloodSport where the Kaijins are KilledOffForReal, but in actuality it's a StagedShooting PropagandaMachine made to glorify the Dragon Keepers as the heroes of Earth, while the Kaijins are usually spared from death to be recycled for the following week. To the public, it seems the Kaijins permanently chained their ship to Earth and haven't given up on their invasion for thirteen years, but in reality it was the ''Keepers'' who chained it down to prevent the Dusters from going home in order to keep up the farce. D theorises that the only people who know the truth are only just between the remaining Dusters and the Keepers themselves.
* BlessedWithSuck: Despite having {{immortality}}, the Dusters' bodies are highly fragile, and they can experience pain from damage. Even as {{shapeshifter}}s, any disguise they don, human or MonsterOfTheWeek, can be shattered easily with the right amount of force.
* ChanceMeetingBetweenAntagonists: in chapter 2, just as D discovers Red Keeper's identity through a poster next to an elevator, ''Sosei Akabane/Red Keeper himself'' comes out of the elevator and passes by him.
* CorporateSponsoredSuperhero: The Dragon Keepers clearly show that they aren't true superheroes due to them indulging in the profits of their actions. From merchandising to a Sentai military training program and even creating their own T.V. show, they are getting rich and famous from their needlessly cruel actions towards the Dusters.
* DarkParody: In a similar fashion to ''Series/TheBoys2019'', this manga plays on Sentai superhero genre tropes to the extreme. The villains had already lost and they lay at the mercy of the heroes. Now the villains are forced to continue playing their roles by the heroes in fear of the dangerously powerful weapons the heroes used against them. One day, a Duster named D decides that he's had enough of the Sentai and plots to take down the Sentai one by one with the help of a Ranger Cadet named Yumeko.
* {{Deconstruction}}: This is used to deconstruct the whole superhero tokusatsu genre from a henchmen perspective. The "Keepers" are nothing more than a bunch of figureheads who are also psychopaths who repeatablely kill the Duster {{mooks}} just so people can praise them long after the actually battle ended just for glory, and are even willing to kill their own just to stay on top. Meanwhile, the main character, a Duster named D, while sympathetic due to circumstance, is a VillainProtagonist with OrangeAndBlueMorality who wants the Keepers dead, but rather than fight, is forced to bring their organization down from the inside.
* DecoyProtagonist: Early promotional materials indicate the main characters to be the Dragon Keepers themselves, however the plot actually follows VillainProtagonist Duster D, as he sets off on his own plan to infiltrate and defeat the Dragon Keepers from within their ranks.
* DoubleMeaningTitle: ''Sentai Dai Shikkaku'' can refer to the current Keepers, who secretly act like corrupt and immoral people pretending to protect the peace; or it can refer to the team D forms in his qualification test, made up of a group of weak, hopeless people (who even D doesn't want to know the backstory of) who no one expects to move onto to the colored rangers.
* DisproportionateRetribution:
** For having attempted (and failed) an AlienInvasion on Earth, the Dustards were forced to become the Keepers' permanent {{butt monkey}}s, with their ship permanently chained to Earth and not allowed to return to their home planet.
** [[spoiler:Mook F was mercilessly killed by Red Keeper for coming down to Earth on a non-Sunday. The problem is the poor guy ''wasn't'' even causing any harm in the first place, but was just looking for D, who hasn't came home in days. This also gave the Keepers a reason to deploy Ranger Cadets to guard the Dusters' base to prevent other Dusters from having the same idea of roaming Earth without permission.]]
* FantasticRecruitmentDrive: The ''Rangers'', an organization that recruits and trains many young cadets to mainly support and, if needed, succeed the Keepers' mantle should the time comes. They are mostly relegated to ordinary field work such as being security guards for the live battles or assisting the police.
* FiveManBand: Invoked by the Ranger organization, and its archetypes have spread so far that everyone under each Keeper has to adhere to their leader's main personality trait:
** Reds are the leaders, the heroes, and usually have the ego to match. They have a good public face, but they are action first, talk later kinds as well. This can also manifest in a self-centered personality.
** Blues are the second in command. They can talk some sense into the Red, but they have their own brand of justice they'd like to follow.
** Yellows are smart and [[GadgeteerGenius tech savvy]].
** Greens, from what little we see of them, are strong, but they are comic relief.
** Finally, Pinks serve as little more than the emotional center and ''especially'' eye candy. Many people mock those who focus on their form as "trying for Pink", and pinks are generally kept to a supporting role.
* ImmoralRealityShow: Thirteen years of Sunday battles have led the entire public to treat it as a BloodSport, constantly looking forward to the Keeper's slaughtering of the MonsterOfTheWeek every week while heavily jeering at the Dusters.
* TheMole: D's main plan was to be one within the Rangers in order to get close enough to the Keepers to eliminate them. Yumeko reveals herself to D at the end of chapter 2 to be one against the Keepers as well, but for a different reason.
* MookPromotion: Played with. The Dusters are forced to come up with a MonsterOfTheWeek every week, which whoever is on duty transforms into and replicates the appropriate abilities to fight with. Due to their {{immortality}} (and the fact that the Divine Weapons used on stage [[StagedShooting aren't the real ones]]) however, once defeated they revert back to being a normal mook and retreat to their fortress to recover, [[PunchClockVillain letting another mook take the next shift the following week]]. This was how they were able to keep this up for ''thirteen years''.
* NoNameGiven: D's default [[HumanDisguise human form]] never had its name revealed. One would think he would have had used a human name to register with the Rangers, but his result slip did not state his name and was instead ''signed off by Hibiki'', due to the latter being assigned as his mentor. Characters that know his true identity also explicitly refer to him as "Mook/Footsoldier" rather than using any name he provided for his disguise.
* OneLetterName: The Dusters are all each named "A" to "Z". This also heavily implies they only have ''[[SuspiciouslySmallArmy 26 men]]'' within their ranks.
* ThePowerOfFriendship: Subverted. In the fight of D against Hekiru, Hekiru makes a grand speech about how it is the power of his bonds with others and their support that makes him strong enough to fight D in typical shounen fashion, but because D is an alien, the concepts he keeps spouting are totally foreign to him and he doesn't understand or care about them, but he points out that it is not his feelings or convictions that are beating D, it's the fact he has a weapon that was tailor-made to kill those like him. Hekiru takes him up on this challenge and drops his weapon promising that the feelings others have for him will work even if they were to fight bare-fisted, but D sends him flying with a single punch, at which point he changes his tune to say that [[MovingTheGoalposts the feelings of his friends are imbued in his weapon instead]].
* SecretTestOfCharacter: The Cadet Graduation Exam consists of ten cadets forming pairs of two and set to steal a key from a more experienced color Ranger. D, in disguise as Sakurama, deduces that there is only one key per color so only one will graduate, meaning the Rangers expect you to betray your teammate. [[ChronicBackstabbingDisorder He's thrilled to have the chance.]] This is subverted later when [[spoiler:Shion determines the real test of character: forming a team of five different color cadets and co-operating to get all the keys, abandoning D entirely]].
* StagedShooting: The weekly Sunday battles. The "Divine Weapons" the Keepers use there are non-lethal substitutes that purposely (and painfully) spare the Dusters from death, so as to continue using them for the next show. [[spoiler:Hibiki notices the real Divine Weapon used by Red Keeper to [[KilledOffForReal execute Mook F]] as punishment looked drastically different from the mechanical-looking ones used in the show and marketed as toys.]]
* TooDumbToLive:
** The Dusters are expected to keep up the ruse that their entire organisation and superiors still exist, despite being just {{mook}}s and the only {{sole survivor}}s of it. This results in them having severe difficulty coming up with plans and monster designs as their superiors were the ones handling it all before, to the point ''the Rangers had to provide them reference books and scripts'' to try to give them some ideas.
** A concerned Mook F came down to Earth looking for D ''without donning a HumanDisguise'' just like the latter did[[note]]It could be justified as the following chapter explains different Dusters have different disguise specialities, and human disguises may not have been F's forte.[[/note]]. The public unrest he caused walking around soon caught the attention of Red Keeper, [[spoiler:who [[KilledOffForReal executes him]] for breaking the "No wandering on Earth during a non-Sunday" rule]].
** D himself, despite being shown to be smarter than the average Duster, is very prone to giving in to his reckless impulses, and is ''terrible'' at acting despite having human disguises as his speciality. [[spoiler:It ultimately gets him ''almost'' KilledOffForReal in Chapter 5 by Blue Keeper for attempting to confront the Keepers instead of running away after they found him stealing Red Keeper's Divine Weapon.]]
* VillainWithGoodPublicity: Through the Dusters perspective, the Dragon Keepers are the truly villainous people who gain respect of the public by taking advantage of their weakness and forcing the Dusters to continue playing their roles as the "villains" of the Dragon Keeper show. That said, like any good organization, there are members who are more self-serving and many who are dedicated to the surface cause of the Rangers.
* WeaksauceWeakness: The Divine Weapons, obtained and developed by the humans within a year into the invasion, are the only items capable of permanently killing the Kaijins. It allowed the Keepers to swiftly execute the Kaijin executives, while the remaining Dusters live in fear of being executed by them.

Given that one of them is later on revealed to be Sosei Akabane/Red Keeper, it's safe to say his four other colleagues next to him are actually the rest of the Dragon Keepers.
