This paper toy is a chibi Heidemarie W. Schnaufer, a Night Witch originating from Karlsland, from the TV anime series Strike Witches, the papercraft created by El Joey. Based on Heinz-Wolfgang Schnaufer. Much like her archetype, Heidemarie has the nickname of "The Spook of St. Trond". The incident that originated that nickname became the base for her story in the manga "Kimi to Tsunagaru Sora".
A rare case of a single witch possessing multiple inherent magics, not only she has the magic-radar characteristic of Night Witches, but also a unique night vision ability that allows her to see clearly in the darkness by relying on starlight. [Source: wikia]
