Tbh, it's expected on the first place because Akari is a scientist. Fictional intellectuals are on par with superpowers in general, if someone's not physically fit and able, the other main way to shine is being a scientist, they're as valuable as fighters in toku as they can create anything, they're typically the one with greatest contributions in any character role, like protagonists such as Sento, antagonists such as Ryoma, or heroines like Akari you said here. I think to talk about being useful, it's kinda unfair to criticize people who aren't scientists to be not as useful as scientists. I knew from the beginning even when I was annoyed by Akari forcing her scientist beliefs to anyone.

I thought the change by getting rid of the gas only means turning themselves good/better person. Being goofy, ridiculous, and embarassing aren't inherent part of being good though. IIRC it's done due to real life reasons of Gentoku actor's relatives watching the show.

Seems that for over the top personality (or being a comic relief) can only work for everyone when you're also morally bankrupt, like Kuroto....

Ironic here, when usually Alain is praised as the saving grace of Ghost.

So I thought Alain was the best part of Ghost...but after his big arc, I feel like he didn't do much interesting.

Also, my friend and I loved Onari's antics. Literally the only thing I didn't like about Ghost was how underdeveloped the final act seemed. The rest was fun.

Is it possible for one person to turn into two Another Riders?

Another Fourze answers that question for you.

That's right! It could work in some way.

If Ora became an Another Rider herself, she could become both Calibur & Kiva-la. Change into either one. It could be a possibility.

Oh man, I totally forgot Kiva-la existed. I've never seen Decade, but I loved Kiva and I really like Kiva-la's design. Is she in anything other than Decade?

Well, scientists, like fighters, are also can be different. You don't have to look far for an example: Rinna from Drive worked much more for comedy than for practical use. As for scientific beliefs, wasn't she herself being asked to believe in mysticism because of Takeru's transformation into a ghost? Plus, didn?t it turn out at the end that she was right and there was no rational (albeit fantastic) explanation?

Exactly! He's super good up until the show decides his arc is over and he is just going to be funny takoyaki boy, with occasional faint glimmers of what made him so interesting in the first place.

Nah, she's a Decade character

She shows up briefly at the end of Rider Time Decade vs ZI-O to help fight Ohma ZI-O.

It was suit only as her actress didn"t reprise her role.
