This girl here is known as Funoi san.
She’s quite famous on pixiv and twitter but I don’t know what anime, game or company character is she from.
Funoi san paper craft here is made by afro_da_afro guy from Japan. He draws and makes a lot of 3D images of Funoi san.
You can check his pixiv and twitter with the same name. It’s full of Funois.
The only other thing I can tell about her is that she is supposed to be a dog.
Other than that none. I’ve seen her character and pepakura model of different version before but don’t know anything much. Perhaps you guys can tell me instead?
