That's pretty much all of the JP talent, yeah? With A-chan in, I guess Nodoka might be involved as well. And I guess YAGOO, and the holostars would be a surprise. While Coco, Rushia and Aloe are here I'd be really surprised if the artist adds in Hitomi Chris.

Are those helis the po-po? Oh my~! I didn't know A-chan was a black hat.

So A-Chan is the person in yellow in both Roboco and Suisei episodes.
