This papercraft is No-Face (Kaonashi), an odd and lonely spirit introduced in the Japanese animated fantasy film Spirited Away, the paper model was created by tamaya. No-Face is shown to be capable of reacting to emotions and ingesting another individual to gain their personality and physical traits.
As a lonely creature who seeks attention from Chihiro after having developed an obsession for her after being kind to him, No-Face first appeared a very timid and soft-spoken spirit whose vocabulary consisted of grunts and moans as opposed to understandable words. Not knowing much about The Bathhouse or about other spirits in general, No-Face learned by example.
Exposed to the crooked thoughts and greed of the workers, he quickly grew to encompass their personalities, hoping that his endeavor to be like those around Chihiro would eventually garner her affection for him. This ultimately brought the opposite effect. However Chihiro is somewhat true to No-Face after she invited him and accepted help from him. While fleeing from the obviously dangerous monster, Chihiro calls him twice (forcing to follow her) and also accepts as a co-journer into the train. At this stage No-Face is no longer aggressive, obeying Chihiro's orders like "sit and behave yourself".
As a monstrous out-of-control being, No-Face exhibited all the negative traits of those it has swallowed; becoming a brash, arrogant, loud and selfish creature whose obsession with Chihiro has proved troubling for everyone.
Towards the end of the film No-Face meets with Zeniba, another witch that works alone, in comparison to Jubaba that runs a big house with a complex hierarchy. Probably also trying to match the rules of the new tiny society, No-Face starts spinning and knitting and appears really good in that. No longer dangerous, he accepts Zeniba's proposal to stay with her as a worker.
That way No-Face seems just reflecting his surroundings. It is the corruption and negative thoughts of The Bathhouse that have made him a dangerous monster.
When first introduced, No-Face appeared semi-transparent while shifting in and out of visibility. His figure resembles that of a long black tube. While it is unknown if No-Face has a "body", it is shown that he has legs and feet with the capability of leaving footprints as he walks. An ominous expressionless mask with purple highlights is plastered on his "head" of sorts, and while there is a "mouth" painted on the mask No-Face has shown that his real, expertly hidden mouth is larger than the one on his mask.
When in a more monstrous form, however, No-Face appears completely opaque. Having swallowed Aogaeru, his limbs became more frog-like and apparent with its large mouth completely revealed. After eating Aogaeru, it has the same voice as Aogaeru. It is also shown to be able to pull its mask into its body and to stretch its limbs indefinitely. When fed the River Spirit's Medicine however, No-Face began to leave sickly trails of black sludge and regurgitated foods behind as it moved, reforming back into his usual state after spitting Aogaeru out.
