This papercraft is Haku's Dragon form, based on the Japanese animated fantasy film Spirited Away, the paper model was created by Michaela. Haku is Nigihayami Kohakunushi's nickname, the twelve year-old deuteragonist in the film.
Haku is a Yubaba's Apprentice, and second-in-command at the Bathhouse. He looks to be in his teens, and has a lean build. He has dark hair in a bob haircut, sharp grey-green eyes, and thin eyebrows. He wears a white kimono with blue trousers, along with a purple sash around his waist. As a River Spirit, he has the ability to transform into a dragon; an animal commonly associated with rivers and water in Japanese culture and mythology.
His dragon form is that of a typical Eastern dragon, with a long snakelike body, horns, flowing whiskers, and a lupine face. In this form, he is primarily white with a turquoise mane. He can fly, and he seems to have the ability to interchange between human and dragon forms at will. [Source: wikia]
