These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Mitsuzane telling Kota to ditch the Sengoku Driver brings to mind several interpretations. Is he really looking out for him and finding a way to boycott Yggdrasil or is he just manipulating him into doing so to save his own skin? Is what he said to Kota about no longer keeping secrets or worrying Mai something he's telling Kota or himself? This can be applied earlier on, when he warns Kota against going public with the story about Yggdrasil. Is he seriously concerned for the safety of his friends or is he trying to make sure Takatora doesn't find out about his double life?
To further illustrate this, a later episode has Mitsuzane sneaking in Yggdrasil and getting data from them, then claims to his brother that he plans to use it against Yggdrasil, though his brother believes he's just doing it to challenge him.
Sigurd telling Kota about how hunting down monsters is part of being a Rider split the fanbase (see below). One question remains: was he actually serious and considered the job akin to Shoot the Dog? Or was he just trying to break Kota's spirits by telling him that hunting down humans who have turned into monsters is all a Rider is good for? Or perhaps he's just trolling For the Evulz? Considering Sigurd is Sid, chances are that the "actually serious" explanation isn't that likely.
Awesome Moments: Like with any Kamen Rider series, the first Henshin and ensuing battle.
Awesome Music: DON'T SAY NO! JUST LIVE MORE! DON'T SAY NO! JUST LIVE MORE!
The "Wärring" issue came up again when the show introduced the Drivers' inventor Ryoma Sengoku, who named the Sengoku Drivers after himself; and Æsir called him "Ryoma Wärring" in order to keep the connection.
In Episode 14, the Urobuchi trap sprung and revealed Gaim to be a deconstruction of Kamen Rider as a whole, with one of the Riders discussing how killing monsters is justice being the subject that people are split upon as they try to define what is justice and seeing if he was in the right for killing a monster who used to be Hase.
Crazy Awesome: Oren takes about five very weird concepts, and somehow combines them into being an awesome badass.
Hell, the melody that plays before he transforms could count too.
And in different ethnic flavors as well - Jidai Geki-ish for Gaim, Zangetsu, and Kurokage, Knight Herald-ish for Baron and Gridon, Chinese-style for Ryugen, Arabic for Marika, and American Guitar for Bravo.
The melody played whenever the Energy Riders transform, you just can't get them out of your ears.
Also, the opening theme, "JUST LIVE MORE".
Ensemble Darkhorse: Oren Pierre Alfonso / Kamen Rider Bravo, mostly for being the source of most of the show's humor after his debut.
Hannibal Has a Point: While Sid is a villain and more notably a Hate Sink, it might be hard to actually condemn his reasons for killing Hase, since Hase was acting more like a monster than a human and it didn't seem like he'd come to his senses any time soon, if at all.
The original Kamen Rider is usually called Kamen Rider Ichigo, so that people can differentiate him from Kamen Rider Nigo. Here, a powerup called "Strawberry Arms" exist. Strawberry in Japanese is 'ichigo'note though with a short 'o' instead of a long one.
Maybe we'll have another one if Gaim in Strawberry Arms vs Zangetsu, making Bleach fans love this possibility.
Now it's getting more hilarious considering that Gaim will get the Kamen Rider Ichigou's lockseed in the Showa vs. Heisei movie.
The last Second Rider to not have a debut in a movie was also named Kaito.
For that matter, Morning Rescue, an orange juice, was associated with Madoka due to the ad airing alongside the series. Now, Urobuchi IS doing an orange-themed Rider...
At the same time that this show was airing, the season premiere of a well-known show had the plot of its own forest invading the normal world. Soon after that, Helheim starts its own invasion.
Fans are wondering what will happen if Zangetsu (A melon rider) meet a melon-loving Mamodo that even has a song and dance for his favourite fruit.
Ho Yay: A brief moment in #9 when Zack and Peco get awfully close to Kota and Micchi during the talk with Team Baron.
Quite a few fans have wondered where exactly Ryoma◊ was looking in #12...
You can be forgiven if you forget Mitsuzane has a crush on Mai given how Micchy spends almost all of his time as Kota's Psycho Sidekick, being willing to do anything to make sure he's happy.
Love to Hate: Oren is a complete Jerkass who deserves some sort of punishment, but he's also a hilarious Badass.
Moral Event Horizon: Sid personally crosses by killing Hase, especially since he was the one who led him to his downfall by giving him the Sengoku Driver, though even Takatora knew that, hence why he let Sid do the job.
Ryoma crosses by allowing Sid to kill Kouta in #21, knowing full well that Sid despises everything about Kouta, if only to enhance his research.
Narm: Whenever they access the Lock Seeds, and zippers open up in the sky.
Rule of Cool: Kamen Rider has had some absurd combinations in previous shows, but Gaim has to take the cake: this is a show about Teenage Breakdancing Samurai Mon-Training Biker Fruit Superheroes.
Many people, thanks in part to Values Dissonance, took a disliking towards Akira after her speech in #3, some even praying for her death.
On a smaller scale, Micchy is getting this for scheming behind his brother’s back. Some fans go on to call him the evil Kureshima brother of the two, simply for using whatever influence he has to secretly escape his golden cage. Meanwhile, Takatora’s deed of nearly killing Kota is completely overlooked.
As of episode 12 Jounoichi may be becoming this after abandoning Ryuji once his belt was destroyed.
There are some who don't like Mai for fangirling over Bravo not realizing what an utter jerk he can be (the Irrational Hatred over Kota being an Aquarius, for example)
Serious Business: After the Ornac controversy (see above), one Anon (later dubbed NDAnon) announced his decision to sub the series himself with a more direct translation. The whole thing was completely drama-freenote NDAnon expressed admiration for Æsir in general and their translator Magenta in specific, but said he wanted to do things his own way; Magenta in turn said it was a good idea and praised NDAnon's Japanese skills, but that didn't stop others from declaring a "Subgoku War" between all the fansubbers.
Surprisingly Improved Sequel: Fan reaction to Gaim is very high compared to last year's Kamen Rider Wizard, which is considered to be the weakest Neo-Heisei show. Not even halfway through its broadcast it is being lauded as one of the best Neo-Heisei, if not overall Heisei, series.
The Woobie: Ryoji Hase. By #12, he's lost everything. He has no Sengoku Driver, Jounochi states that he was being used, his teammates disown him...damn. And to make matters worse, he is transformed into an Inves. And was then put down like a rabid dog by Sigurd. This guy could not catch a break...
Shin Megami Tensei meets Kamen Rider is picking up popularity, especially since #20 introduced a Law vs Chaos division within the Next Generation Riders, with the latter supporting a similar idea of Social Darwinism the Chaos faction in Shin Megami Tensei usually supports and #21 reveals that [[spoiler:Takatora, who represents Law, is willing to destroy Zawame City to protect mankind, which the SMT Law faction attempts to pull off in most games. They also have something called "Project Ark" with its obvious implications. Of course, in the middle of everything, there's Kouta, who looks like he'll attempt to trail his own path different from either faction, like the Neutral path of the main heroes in most games.
There's also the basic function of the lockseeds, summoning and controlling interdimensional monsters, similar to the COM Ps in the Shin Megami Tensei series, especially starting from the second arc where they aren't limited to Invess games and some people start using the Invess to do whatever they wanted, similar to various minor antagonists in Shin Megami Tensei series, especially common in the Devil Survivor subseries.
