Looks like Sketchbook ~ginormous eyes~ to me. Bet TheBigN will love it.

UPDATE: TheBigN e-mails:

The trailer was actually a bit more subdued than I thought it would be. From my experience with the manga, if the anime is a direct adaptation, things should be a lot more crazier and wackier.

I dunno, Torako jumps out of that window in the trailer. Not even Tomo has pulled a stunt like that.
