lol @ Sato after he ate his, also later in the video "ORE WA KABUTO DA". Nice find.

Renge for me, Misaki is a close second.

I think by the end of it I liked all the riders for various reasons. I liked Kickhopper's insanity, Tendou's ability to do just about anything and appear out of nowhere (to the point of being humorous sometimes), Tsurugi for being both hilarious and being completely awesome in combat, And Gatack for...

Wakana. No doubt about it, she has a lot of personality.
