I just really love the Rider Chips- not that Nanase Aikawa isn't good, but Ricky's voice just makes me happy xD
But yeah, they're both very cool.
I don't like the remixes that much, but honestly, nothing is as bad as the verses of the Rider Chips remix for Shounen yo. The chorus sounds great, but the verse is just so off...

For those who haven't heard and seen it yet...

I very much prefer that one as to the first opening.

The video composition is much better for Elements. But I kinda learned to love the randomness of the clips for Round Zero. Kenzaki peeling an apple and Hajime playing football sure is fun to see xD I think those were puns on what they answered to the question about their "special skill" in interviews. Mutsuki does his henshin pose, just with a hat, Tachibana does some cool moves and Koutaro drinks milk of course. But I still don't get why Shiori plays with a piece of paper or plastic.

Honestly I prefer Round Zero more. :)

Maybe to show that she can't really fight? I mean it looks like she trying to kick/hit it with little skill/effect.

Considering how random the others are, I don't think there's that kind of meaning. Especially not considering the fact that she wasn't presented as someone who wanted to fight or was a warrior in the first place.

Just saying. *shrugs and chuckles*

Let's just leave it at that: Blade is super-random, but really awesome xD

I'm kinda upset that Koutaro isn't Leangle.

That'd be amazing. I love Kotaro. :D
