This is a ANBU mask papercraft, based on the Naruto series, the paper model was created by Guruh memory. The ANBU, short for Ansatsu Senjutsu Tokushu Butai (Special Assassination and Tactical Squad), take orders directly from the Kage, performing special high-level missions, such as assassinations and torture.
The ANBU usually work in teams formed to the requirements of the mission, ensuring maximum success. The shinobi in the ANBU are hand-picked by the Kage; chosen for their individual capabilities and special skills. Age, gender, background, or previous rank bear no weight in this decision. Members can also leave the organisation, as Kakashi did for unknown reasons to return to the regular forces. They wear their mask even in their own village, for their identity as an ANBU agent is to be known only by the Kage and village elders, with the exception of Konohagakure's "Root" ANBU members who, unless ordered to, will otherwise only act on Danzō Shimura's orders.
There are apparently no true ranks within the ANBU, unlike within the regular forces. Team leadership and hierarchy seem to be based on merit and experience. The leaders of the teams are called squad leaders, a position held in high regard.
Most ANBU predominately wear some kind of porcelain mask to conceal their identities. Konoha ANBU predominantly wear animal-styled masks with some opting for more menacing looking creatures, Kiri ANBU wear masks with slits for eye-holes and the village's symbol printed on it; these may or may not have patterns on them as well. Suna ANBU seem to wear pieces of cloth to cover the lower-halves of their faces leaving only their eyes visible. In the anime, Suna-nin were depicted wearing porcelain masks as well, modelled to resemble oni. They also have standard uniforms which for Konoha ANBU consist of black clothing and grey chest armour, metal arm guards and gloves, ninja sandals with spikes for travelling into mountainous regions, three ninja pouches on their back-waist and a signature spiral tattoo on their shoulder. Some Konoha ANBU wear black cloaks over their standard uniforms, and squad leaders may wear white cloaks. Most of them carry a sword, which is usually strapped to their backs. [Source: wikia]
