This paper toy is a chibi Kou Houju (more commonly known by the name Kou Kijin), the chief minister of the Department of Treasury and Taxation, from the manga / anime / game series Saiunkoku Monogatari, the papercraft is created by Larry-San.
Almost no one knows his original personal name and he is widely regarded as mysterious and eccentric, mostly because he constantly wears a wide array of unusual masks.
Kijin has a highly unusual appearance. He leaves his hair loosely flowing instead of binding it up according to custom, and is almost never seen without one of the masks from his wide collection. These masks usually conceal his entire face, although they have a lower panel that can open to uncover his mouth when he eats or drinks in public. Many of the masks were made by Reishin Kou, who is one of his few close friends and with whom he often enjoys meaningless arguments.
Although his masks are widely assumed to conceal a deformed or hideous appearance, in fact they serve the opposite function by concealing a face of such dazzling beauty that it can drive people insane. The masks also muffle the true sound of his voice, which is as silky and beautiful as his hair. [Source: wikia]
