Who are the characters on the girls' planes in Shirobako?


In the intro to Shirobako, the girls are shown flying in fighter jets. Each of
them has a design under the cockpit - presumably related to the characters.

I can't figure them all out though.

This is the easiest one, the two toys are delusions of Aoi's that she
interacts with often during the show.

Shizuka's plane has the pig with a plum-shaped nose. This was the character
that she got to play in costume during one of the episodes.

Misa's plane has a depiction of a penguin - from the show that inspired her to
join the company she was making tires for.

However, I don't know what the final two are referring to.

Did I miss something obvious? Any ideas how these pictures / characters are
related to the cast?




Ema's is one of the characters from their _Seven Lucky Battle Gods_ anime.

I'm not sure about the one for Midori, but it might be the guy behind her in
the red armour.
