Kamen Rider Decade is one of those shows that is hard to talk about without sounding like you are arguing with yourself. On paper, it has one of the coolest ideas in the franchise. A Rider travels between worlds, uses the powers of past Heisei Riders, and becomes tied to the fate of the entire multiverse.

That should be amazing. Sometimes it is. But Decade is also one of the most divisive Kamen Rider seasons because it feels like it is constantly racing against the clock. With only 31 episodes, a cliffhanger ending, and a movie that is supposed to explain everything but mostly creates more questions, Decade is a season that fans still debate for a reason.

So is Kamen Rider Decade a brilliant anniversary experiment, or is it just a rushed mess? Honestly, it is kind of both.

What Is Kamen Rider Decade?

Kamen Rider Decade follows Tsukasa Kadoya, a young man with no memory of his past who discovers that he can transform into Kamen Rider Decade. He is told that different Rider worlds are beginning to collide, and the only way to stop that from happening is to travel through the worlds of the past Heisei Riders.

The setup is simple enough at first. Tsukasa travels from world to world, meets alternate versions of past Riders, and slowly learns more about his role in everything. He is joined by Natsumi, her grandfather, Yusuke Onodera, who is an alternate version of Kuuga, and later Daiki Kaitoh, also known as Kamen Rider DiEnd.

The big mystery hanging over the show is Narutaki constantly warning everyone that Decade is the “Destroyer of Worlds.” That title gives the show a darker edge and makes Tsukasa feel less like a normal anniversary hero and more like a problem the universe itself is trying to solve.

Why Kamen Rider Decade Still Gets Attention

Even with all of its problems, Decade still has a hook that works. The idea of a Rider who can travel through different Rider worlds and use the powers of previous Riders is just cool. It gives the show a built-in sense of scale that most anniversary seasons would love to have.

Decade also has one of those designs that stands out immediately. You may love it or hate it, but you are not going to forget it. The card theme, the magenta color scheme, and the barcode-like helmet design all make Decade feel different from every other Rider around him.

That is why the show is still worth talking about. Even when Decade falls apart, it falls apart in an interesting way. It is not boring. It is not safe. It is not just another standard Rider season. It swings big, and that alone makes it memorable.

The Story Setup Is Strong

The first part of the show is where Decade works best. Tsukasa visits different Rider worlds, meets alternate versions of familiar heroes, and slowly pieces together what Decade is supposed to be. The show gets to play with past Rider concepts without being completely locked into old continuity.

That was both a strength and a problem. For newer fans, the alternate worlds made the show easier to jump into. For longtime fans, some of the changes felt strange because many characters were recast or reimagined instead of simply bringing back the original versions.

I do not think that idea is automatically bad. If you are going to do a multiverse anniversary show, alternate versions make sense. The issue is that Decade does not always have enough time to make those worlds feel complete before moving on to the next one.

Decade’s Powers Are Cool, But Final Form Ride Is Weird

One of Decade’s main abilities is using Rider Cards to transform into past Kamen Riders. That gimmick alone is enough to make him feel like a true anniversary Rider. He does not just reference the past. He literally carries the past with him through his cards.

Then there are the Final Form Ride Cards, which are where things get weird.

• Kamen Rider Blade becomes a giant sword.
• Kamen Rider Kiva becomes a giant bat monster.
• Kamen Rider Kuuga becomes a giant beetle-like form.

I get what they were going for. It is a toy gimmick. It gives Decade a visual way to use other Riders in battle. It creates memorable action scenes. But it also feels strange because Decade is literally turning other Riders into tools and weapons.

Some fans see that as fun and creative. Others see it as disrespectful to the Riders being transformed. I land somewhere in the middle. I think the idea is memorable, but the execution is hit or miss. It is one of those things that makes Decade feel unique, even when it also makes you ask what in the world you are watching.

Where Kamen Rider Decade Starts Falling Apart

The biggest issue with Decade is that the show starts stronger than it finishes. The early episodes have a clear structure. Tsukasa travels to a Rider world, gets pulled into that world’s problem, learns something, and moves on. It is simple, but it works.

Once Decade collects more of the Rider Cards, the story begins to lose focus. Questions start piling up faster than answers. Daiki can travel between worlds, but the show never fully explains how he is able to do that in a way that feels satisfying. Decade’s cards go blank after fighting Dark Kiva, but the way that problem is resolved does not feel as important as it should.

The show keeps introducing ideas that feel like they should matter more than they do. That is the frustrating part. It is not that Decade has no ideas. It has too many ideas and not enough time to make all of them land.

Why Was Kamen Rider Decade So Short?

One of the reasons Decade feels rushed is because it only has 31 episodes. That is much shorter than a typical Kamen Rider series, and you can feel it. The show has a huge anniversary concept, a multiverse story, returning Rider elements, new characters, mystery, and a major final conflict. Then it has to cram all of that into a smaller episode count.

That shorter length would not be a problem if the story was tighter. But Decade often feels like it is still setting things up when it should already be paying things off. By the time the final episodes arrive, the show does not feel ready to end.

That is why the ending frustrates so many people. It does not feel like the natural conclusion of a finished story. It feels like the show ran out of road.

The Ending Is Still the Biggest Problem

The final episode is where Decade’s reputation takes the biggest hit. Instead of giving the story a clean conclusion, the show ends with more questions. Tsukasa learns that the real Kamen Riders, not just the alternate world versions, are connected to his journey. But instead of giving him a clear answer, they give him another cryptic mission.

Then the Rider War begins. Tsukasa faces off against the past Riders in a battle royale, and just when it feels like the story is about to explain what Decade really means, the show cuts away.

Even worse, the final shot shows DiEnd aiming his gun at Tsukasa and firing. Then the screen fades to black.

That is not a real ending. That is a commercial for the next thing.

The Movie Does Not Fully Fix It

The follow-up movie, Kamen Rider Decade: All Riders vs Dai-Shocker, is supposed to help resolve the story. Instead, it adds more confusion.

The movie introduces the idea that Tsukasa was connected to Dai-Shocker, the villainous organization, and it plays with the possibility of different versions or sides of Tsukasa. That could have been a strong reveal if the show had built toward it cleanly. But because Decade already had so many loose ends, the movie feels like it is adding another layer before fixing the first one.

There are cool moments in the movie. There is big anniversary fan service. There are plenty of Riders on screen. But if you were hoping for a simple explanation of what Decade was building toward, the movie does not completely solve the problem.

What Kamen Rider Decade Gets Right

For all of my complaints, I do not hate Decade. In fact, I think the reason people still argue about it is because there is a lot to like.

• The core concept is strong. A Rider traveling through the worlds of past Riders is a great anniversary idea.
• Decade himself is memorable. The suit, the cards, the attitude, and the “Destroyer of Worlds” idea all stand out.
• The action is fun. Even when the story is messy, the show usually has something entertaining happening on screen.
• The fan service works in moments. Seeing Decade interact with Rider history is still part of the appeal.

Decade is not a boring failure. It is more interesting than that. It is a flawed show with a concept strong enough to survive the flaws.

What Kamen Rider Decade Gets Wrong

The problem is that Decade never fully earns the scale it is reaching for. It wants to be a major anniversary crossover, a mystery story, a multiverse adventure, and a character journey for Tsukasa all at once. That is a lot for any show. For a 31 episode show, it is even harder.

• The story loses direction in the second half.
• Some character arcs feel incomplete.
• Important questions do not get satisfying answers.
• The ending feels like a setup instead of a conclusion.
• The movie does not clean everything up as much as it should.

That is why Decade can be fun to watch and frustrating to finish. It has the energy of something huge, but not always the structure needed to support it.

Final Verdict: Is Kamen Rider Decade Worth Watching?

Yes, I think Kamen Rider Decade is worth watching, but with the right expectations.

If you want a clean, tightly written Kamen Rider season with a satisfying ending, Decade is probably going to annoy you. The story is messy. The final stretch is rushed. The ending is still one of the most frustrating parts of the show.

But if you enjoy anniversary seasons, multiverse stories, strange gimmicks, and Riders who feel larger than life, Decade is worth your time. It is not one of the smoothest Kamen Rider seasons, but it is one of the most interesting to talk about.

What Do You Think About Kamen Rider Decade?

Did Decade’s anniversary concept work for you, or did the ending ruin the ride? I still think there is a good show buried inside all the chaos, but I completely understand why fans are split on it.

Until next time.
