This papercraft is the Yuuri Asuka, based on the Puella Magi Kazumi Magica series The Innocent Malice, the paper doll is created by seisakudiary. Yuuri Asuka is a character appearing in Puella Magi Kazumi Magica: The Innocent Malice.
Yuuri appears only in flashbacks, having died before the beginning of the series. Her first appearance is in a single panel in Chapter 4 before appearing in an extended sequence in Chapter 5. The Yuuri seen in other chapters of Kazumi Magica is in fact her friend Airi, who has taken her appearance and identity.
Despite being deceased at the beginning of the series, she is important to Kazumi Magica's story. A magical girl, her wish was to cure the life-threatening illness of her friend Airi.
Yuuri was kindhearted and caring, trying to help other people. She seemed to enjoy both cooking and eating, and was devoted to her friend Airi. In fact, she became a magical girl with the sole purpose of saving her life. This devotion was reciprocated by Airi, as seen by her later actions.
Yuuri's magical girl form was only seen briefly. However, her weapon was a giant multi-needled hypodermic needle, likely used as a firearm. She also had healing powers, derived from her wish, which she used to heal other children with incurable diseases. However, using this power puts stress on her Soul Gem.
Her outfit is also considerably different from the one Airi later dons, though they have the same color scheme and general aesthetic.
