Sentai Daishikkaku

For the past 13 years, the Nefarious Monster Army have appeared beneath their floating fortress every Sunday to advance their goal of conquering Earth. Luckily, the Dragon Keepers are here to save the day! Having defeated the majority of the monsters during their initial invasion, the heroes now routinely show up to clear away any remnants of resistance. Unbeknownst to the public, however, every fight beyond the first has been a deliberate show put on by both sides: the Dragon Keepers reap the fame and prestige from fighting imaginary enemies, while the surviving weakest monsters, altogether called Dusters, are allowed to live for another day.

Sentouin D, a Duster tired of living this life of shame, leaves the fortress in an attempt to overturn his fate. With the unexpected help of the mysterious ranger Yumeko Suzukiri, he discovers the key to defeating the Dragon Keepers lies in their Divine Artifacts—ultimate weapons crucial to the rangers' transformation and unique powers. Teaming up with Suzukiri to infiltrate the garrison of Red Keeper Sousei Akabane, Sentouin D must defy all expectations to save his species from the cruel hands of humans.

Go! Go! Loser Ranger! takes the familiar Super Sentai trope and flips it on its head, delivering a fresh and engaging twist on the classic hero-vs-villain dynamic. From the very first episode, the series presents a world where the so-called "heroes" might not be as noble as they seem, and the so-called "villains" may not be the ones to root against.

One of the strongest aspects of the anime is its protagonist, Fighter D, a low-ranking monster who dares to challenge the corrupt Ranger organization. His journey is compelling, filled with tension, strategy, and a surprising amount of humor. The show balances action and satire well, ... keeping things exciting while also poking fun at the traditional Sentai formula.

The animation and fight choreography are solid, with dynamic battle scenes that make use of vibrant colors and unique abilities. The soundtrack complements the action well, and the character designs—especially for the monster cast—are distinct and memorable.

The story does a great job of subverting expectations, but it does take a bit of time to find its footing. Some of the supporting cast feels underdeveloped, and certain episodes slow the momentum a bit. However, the twists and world-building make up for these minor flaws.

Overall, Go! Go! Loser Ranger! is a fun and refreshing take on the superhero genre with a strong mix of action, humor, and intrigue. While it doesn’t fully break free from some typical anime tropes, its unique premise and execution make it a standout in its genre. Definitely worth a watch, especially for fans of unconventional hero stories.

Mixed Feelings

“Go! Go! Loser Ranger!” is what happens when a pretty good idea is held down by a terrible mismatched mix of genres.

I’m a sucker for genre deconstructions. My favourite story of this type, and in general, is “Miracleman” by Alan Moore. Needless to say that when I read the synopsis for “Go! Go! Loser Ranger!” I was hyped. I thought it would be a Super Sentai deconstruction in a similar way that “The Watchmen” (also by Alan Moore) or “The Boys” were a deconstruction of Marvel and DC superheroes and… to a degree it is. It has some elements of a competent deconstruction but is ... held back by terrible comedy timing and the absurd world it takes place in. Does that make it a bad anime? I don’t think so. It does however make it less than competent deconstruction. I warn You to keep that in mind if You are also a fan of deconstructions. Thing is that episode 2 and 3 work as a solid prologue to an amazing deconstruction and are even played as such. Episode 1 is another beast but I’ll get to that.

Before we start I would like to explain something. I will be talking about “plot” and “story”. Many people use those terms interchangeably. I’m not one of those people, so to make sure everyone is on the same page…
I use the definitions for “plot” and “story” as Lisa Cron describes them:
“What happens in the story is the PLOT, the surface events.”
“STORY is about how the things that happen affect someone in pursuit of a difficult goal, and how that person changes internally as a result”.

I’m not gonna lie, I like the story. A story about a frustrated, basically slave, that decides to fuck over his tormentors. It’s a cool idea, not a very original one but a cool one. A bonus is that no one in this show has a moral high ground. Everyone is an asshole in one way or another, a sociopath or has less than righteous motives and plans. The MC (Fighter D) is literally a creature created to fight, kill and conquer humanity. He even has a goal to take over the world and be top dog. The drawback to this approach is that there isn’t really anyone to root for. On one side we have psycho rangers, on the other a power hungry idiot. I really couldn't care less about any of them if I tried. Maybe I would feel differently if Fighter D was a man with a plan but the truth is he doesn’t think things through (apart from 3 situations in later episodes) and wings it most of the time. He has a goal. Cool. But has no plan of achieving it.

When it comes to the plot… I’m not a fan of the first half. For the first 5 (and a lot of 6) episodes it’s like the plot can’t decide what it wants to be. There are even moments when Fighter D (I refuse to call him just D. D is an awesome and competent vampire hunter not a poorly written moron. He’s Fighter D of FD from now on) is relegated to the role of deuteragonist, something that should never happen in an anime that has only 12 episodes.
I will give credit where credit is due, there is a lot of “because of that” type of storytelling here. The problem is that the main beats that are the catalysts of this are mostly the effect of “and then that happened” type of storytelling. In this case it’s not as bad as in some other anime, apart from episode 2, that shit is just bullshit, but it still stands out.

It had so much potential as a hero deconstruction and yet it decided to squander that potential for cheap jokes that kill any sort of drama, inconsistent protagonist and a world full of idiots. Granted, if the world had more than a bunch of people with an IQ higher than room temperature this whole show wouldn’t have happened in the way it does. But that’s the curse of anime in the last 15 years… oh well, c'est la vie.

The first episode actually fulfills its function pretty well. It gives us a brief look at both sides of the greater conflict and does some lifting in worldbuilding without being a straight up exposition dump like some other anime do. Don’t get Your hopes up too much, there is still exposition.
It shows us that the Keepers are machiavellian assholes, the fighters are cowardly peons without any sort of long term plan or even a goal. It also shows us that the world is populated by idiots. It has been 13 years since the invaders came to conquer earth. 13 years. In this time the conflicts were transformed from actual war-like skirmishes into a weekly spectacle. It was also 12 years since the last human died due to a monster attack and no one asks questions about this? I may be autistic but I would assume that if something life threatening suddenly turners into entertainment for the masses there would be questions. After 13 years even “The Simpsons” lost some of its viewership. Everyone just accepts that a force that was hell bent on world domination just attacks now in regular intervals, always in the same place, always with just a small unit and a boss, and only attacks the Keepers. There are shit loads of civilians with only a mere squad of security. If there were more of them they could paint the damn stadium red. Yes they do have an arrangement with the keepers but it’s stated that most people don’t know about it. Yet they still come to a place that would have no business being as safe for them as it is, if this was still a real conflict. I can’t even feel sorry for them. If they die, that’s on them. Natural selection wins.
Listen, if I were to only look at its function I would probably give this episode something like 5 or maybe, MAYBE 6. But alas I’m the type of guy that cares more about the plot and story than just function. There is very little logic and believability in this world. How can I take the drama seriously if the whole world is packed full of nonsense and idiots?

Let’s talk about the moment of the enslave… I mean, the arrangement the Keepers made with dusters. The deal was made 12 years earlier. 12 years. Let that sink in. The Keepers look as if they were in their mid 20's. Let’s say they are 25 (I have no idea if their age is stated anywhere so I might be wrong). 13 years ago when the conflict started they would be around 12-13. So now we have a couple of ways of looking at it. Either this is a different team than the one who made the dead, which isn’t very probable since they look and sound the same. Red even has the same mannerisms as he does in the present. Second. The transformations aged them when they were kids. Which is dumb but was made in “Power Rangers Turbo” with Justin Stewart so I wouldn’t be that much surprised. There is also a third option. The Keepers are in their mid to late 30s. Which is even worse because it implies that grown-ass men (and one woman) in their 30s act like spoiled kids. Furthermore, being in their 30’s isn’t old (I’m gonna tell myself that since I’m at the tail end of my 30’s) but it’s past their prime. They have a whole production line of Keepers and yet, not one Ranger in their 20s was able to outdo someone with their 30s? I could believe this in the case of Red, he does seem to have some unnatural level of strength almost like he spends every Dark Souls game using Strength builds, but the rest? I find it hard to believe the Keepers don’t have early retirements if only to keep the illusion of them being all powerful alive. Also, in Your 30s You tend to change Your outlook on life and what You value in it. Yet all of the Keepers are still acting like spoiled children. Mostly Red but Blue is also cocky and pays for it.

Let’s get to the second part of the show. From around episode 7 (maybe 6 but that’s me being nice) the show changes. It becomes more focused. Almost like the writer took some writing classes when no one was looking. It gets better and worse at the same time. It becomes worse because it mostly loses its unique pitch. Yes we’re still in the universe where Power Rangers are psychos, yes most people are still morons and our MC still has a revenge boner but the show stops throwing garbage jokes anytime something serious happens (still does, but not so much so I count that as a win). The drawback is that it becomes just another tournament / exam regurgitated garbage You see in every school anime these days. It became so basic that I couldn’t even tell You why the exam was so dumb. Granted I’m not sure even the people writing this could tell You that but that’s beside the point.

The infiltration and fucking up an organization from the inside is a good idea. Not many anime and even movies do that. But there is a reason why. It’s really tough to write something like that in a way that doesn’t feel cheap. The best example I can think of, of this type of plot is “Infernal Affair” - an amazing movie that uses an undercover cop and an undercover mob member to create suspense and drama. It’s a masterpiece of writing. The thing is, there are 3 movies in the series and only the first one is amazing. It’s that hard to write this sort of plot. It would be hard enough in a realistic setting, adding a Super Sentai fantasy to it makes it even more so, and adding dumb jokes that don’t land ruins it almost entirely. Probably why, the jokes stop at some point and the show gets better because of it.

The exam arc also shows us another part of FD. His thinking and strategic part. Seriously, the second half of the show proves that he can think strategically and on the fly. Why isn’t this mofo the leader? The way he fools the opposing team to get the key, the way he takes charge of the situation when shit hits the fan and the way he plans the fight during the exam are really solid writing.. With few crappy moments but compared to the rest of the show it’s top notch. For 12 years he didn’t think of leading his own kind? With this kind of adaptability he could become a real threat to the world. So why just now? Oh, right… the plot demands it.
The only thing I would call bullshit is that at some point he reveals his identity to convince someone to join his “cause”. It’s dumb and totally unnecessary. He could have convinced him in so many ways that I would spend a day and a half naming them. Ok, the reveal could have been the final method but the dumb ass barely tried anything else.

Ok… this is getting too long for any sane person to read and I’m not even ¾ of the way I wanted on a list of things I wanted to address so…

At the end of the day I don’t think this is a bad anime. The animation and art style are nice and OST is pretty solid as well. My main grype is that it is positioned as a deconstruction and I guess it does have elements of it, but it’s not a very good one. Shame because the idea has potential and I would lie if I told You I did not enjoy the second half of it.

Preliminary (3/12 eps)

As a loser myself “Go! Go! Loser Ranger!” is what happens when I get reincarnated into another world as a Power Ranger villain lvl 1 crook and I infiltrate the Power Ranger organization to take them down and take over earth or something ...

I’m a sucker for genre deconstructions. My favourite story of this type, and in general, is “Miracleman” by Alan Moore. Needless to say that when I read the synopsis for “Go! Go!
