Is Sci-Fi Kamen Rider better than Fantasy Kamen Rider?

I'm more into Sci-Fi Kamen Rider because most of GOOD Kamen Rider show are sci-fi!

It's rare to have a GREAT Fantasy Kamen Rider show without Sci-Fi Element

How come Sci-Fi work for Kamen Rider but Fantasy didn't work for Kamen Rider?

Den-O and Gaim are popular sci-fi show with Fantasy element but Wizard which is a fantasy show wasn't beloved by many folk

How can we made a GOOD Fantasy Kamen Rider Show without any Sci-Fi Element? Why it hard for Toei to make a good Fantasy Kamen Rider Show?

Double- Sci-Fi

OOO- Fantasy/Sci-Fi

Fourze- Sci-Fi

Wizard- Fantasy

Gaim- Sci-Fi/Fantasy

Drive- Sci-Fi

Ghost- Fantasy

How well do Kamen Rider belts and other henshin devices fit? Are they quite clearly designed for children and therefore won't fit an adult?

Poorly for those exact reasons.
They make official belt extenders, but it's not too difficult to make one out of a normal belt.

Wrist straps are a different case. Those just kind of depends on how big of a person you are.

As Matrix said, kiddie size only, but you can easily modify them to fit you. Don't buy the overpriced belt extenders, waste of money.

I was talking to a friend about cosplaying Takeru and Alain from Ghost, since her hair is very similar to Alain's and she has similar earrings, and was just wondering if the official belt and arm thing would work, or if it'd be better to come up with something else. We're both skinny so it might make things a bit easier, but they're definitely still kids toys.

If you're skinny enough if might just work, but it could be a tight and uncomfortable fit. But as I said you can easily mod them with anything that ties the ends together. As far as alternatives go there are cheaper kid versions which are even smaller so not what you're looking for.

If you don't want to make something yourself you need the DX version. Or just buy a candy toy Eyecon and cosplay them without the henshin devices.

So this and this?

It's certainly be cooler to do it with the devices, but it might just be easier without. But then we can't do cool henshin poses.

Yeah these. Prices are okay too. There's a mildly cheaper alternative for your Takeru cosplay, you could use the Eyecon Driver G, the Grateful Damashii one. But I guess it's not about saving 10 bucks here.

My friend, DustofMetal, and I are slowly working our way towards modifying our Driver belts. Our idea is to fix matching colored cloth to the already belt pieces. We'll start and end where the belts meet the attachment pieces, that way it gives the image of the belt being one solid piece of fabric and not plastic with fabric attached to it.

Ahh, in-universe function, got it. Thanks for clearing that up.

(Man do I wish the KR Wiki page had sections for toys.)
