Mitty's Doll

"Nanachi to Mitty"

- Look, Mitty. It's a bird. It's just like that one that was screeching back then, you know.

Mitty's Doll was a small handmade doll given to Mitty by Nanachi.

When traveling towards Ido Front on the Transportation Vessel together, the pair had heard a "terrible screech" and had inquired whether it was a bird. Later, after escaping Bondrewd and settling at Nanachi's Hideout, Nanachi had made a stuffed animal to represent this bird and to comfort the now debilitated Mitty. The doll was placed in Mitty's arms before being euthanized at the hands of Reg's Incinerator.

In reality, no such bird exists in nature, instead serving as a reminder of their shared experiences and friendship.

Description
In the anime, the doll is shown to be made of green and pink fabric.
