Master of Mosquiton, 1 layer, A4, 1 sketch, oversize 12 tall x 10 inches wide, no background, OVA
A cel of all the major characters from Master of Mosquiton: From left is Yuki, Inaho holding onto Alucard, and Hono. They are blue because they are traveling inside a supernatural blue light. Their destination is the moon. Possessing the O-part allows the holder and any companions to travel there.
The screencap of the scene below shows that there was a blue effect over the cel.
