Fashion and trendiness in clothing is a lot more popular in Japan than it is in the West. I'm not sure about kids, but it's definitely a theme that would resonate with Japanese teens.

If the recent Kamen Rider shows exist in the same universe as each others then how come they never references each others events from each other shows? I mean Fourze reference the W movie on a urban legend website. The Helheim invasion is too big to ignore. It would be cool if there was some references to it in Drive.

I like pretending that each show takes place in its own separate universe, while those cross overs are just non-canon and take place probably in a different universe. Foundation X was in both Fourze and W, and the medals from OOO's were foreshadowed by X. So those three shows are loosely connected. But again in my mind each show is in it's own separate universe. Except Black and Black RX.

Considering they have their own world-wide attack thing in the past with the Roidmudes, it's highly unlikely. Because if the events of Gaim were to be a thing in Drive, the earth would look different and people would still talk about it or at least compare the Roidmudes to the Inves.

I'm aware of the Fourze thing, but I attribute this to it being an anniversary show and they wanted to incorporate the Kamen Rider-legacy somehow. In of itself I don't think it's more than the usual Rider-crossovers.

I don't think any Kamen Rider-show exists in the same universe as another, unless stated otherwise. But they are like a multiverse which crosses lines constantly. Kinda like Dark Souls where time and space keeps overlapping and allows players to visit other worlds which are similar to theirs, yet different.

All of the Showa series explicitly took place in the same universe.

KR is already about fashion

Belts
Buckles
W had a small cape
Skull had a cap
OOOO had medallions
Various ones have had capes
Drive has a FUCKING SASH, which is what beauty queens wear
U all just not seeing it

Everyone here seems iffy about a fashion themed Rider series.

I'm just here waiting for a Senketsu returns confirmation in Rider form (I mean, Kill la Kill was technically 15% fashioned themed, and it did alright).

Well when all we have is fashion to go off I imagine people would feel iffy given how it feels quite unexpected but then kamen rider made fruit warriors work so you never know.

Also at the current moment we don't know if it the main part of the motif, a minor part of the motif or if it actually the real deal.

Kuuga and Agito seem to take place in the same universe. It also possible that Kuuga and Agito also exist in the same universe as the Showa riders going by the Agito PS2 game since the game's timeline has 1971 - Agito in the same timeline together. I think continuity for Rider shows goes like this:

Showa: 1971 - Black RX
Kuuga/Agito: 1971 - Agito
Shin, ZO, J and Ryuki - Decade: All stand alone. They all take place in their own continuity.
W - Drive: 1971-Black RX, Kuuga, Kiva and W - Drive.

I think W - Drive to exist in the same universe since some of the crossover movies where reference in the show. Kuuga was shown in Fourze and Kiva's belt was reference in Gaim. I do wish Toei would build their universe better similar how Marvel studios does.

Wait what?
