This paper doll is the Yuuri (Prototype), based on the Puella Magi manga series "Puella Magi Kazumi Magica: The Innocent Malice". The papercraft is designed by SSN. Yuuri is an enigmatic character appearing in Puella Magi Kazumi Magica: The Innocent Malice.
A magical girl with a mysterious past, she repeatedly clashes with members of the Pleiades Saints. Kazumi is her primary target. As part of her disruptive actions, she can also create pseudo-witches from common humans by embedding them with Evil Nuts, "imitation" Grief Seeds.
Her real name is Airi and her wish was to become the real Yuuri. She blames the Pleaides for the death of the real Yuuri, who turned into a witch and was killed by the Pleiades.
Her life is consumed by a single objective: revenge. Due to the death of her friend, she developed a great animosity towards the Pleiades Saints and now lives to exact vengeance on them. She is ruthless, not only fighting the Pleiades directly, but in also spawning pseudo-witches from innocent humans. They not only attack the Pleiades but also other humans, thus leaving a trail of blood in her path of retribution. She has a particular interest in Kazumi, as she believes hurting Kazumi will hurt the Pleiades the most.
