This paper toy is a chibi Zatsune Miku, a variation of vocaloid Hatsune Miku, the papercraft was created by smilerobinson. Miku Zatsune is Miku's "dark side" with a red theme instead of teal. She is said to be a daring or sexy version of Miku, and is said to sing songs with sexual content.
The personality of Zatsune Miku has not been elaborated on particularly, but she is often depicted as dark or evil. As a fanmade character, she has no direct personality much like the original Vocaloids it is purely up to any fans. [Source: wikia]
