Well I've personally seen 2 karekano cels in my 
life. This one and the one I have :) I've got an 
Asaba cel from episode 5. It's from when Yukino 
is waiting for Arima for the movie date and Asaba 
shows up. Asaba is wearing his hat. It's just 
when he's looking down and blushing. Fully 
centered eyes open and everything :) Wish I had 
made a scan of it. Dont get back to the scanner 
until next week. If anyone is interested in it 
let me know it is for sale. No set price but I'd 
take offers. :)
