Sayaka visits an injured boy named Ky?suke Kamij?, who was a violin player she admired when she was little. After another witch hunt, Mami tells Madoka and Sayaka that she had been involved in a traffic accident and didn't have time to think about her wish. She also lets Sayaka know about the precedents for wishing on other people's behalf. Later that night, as Madoka helps her drunk mother and talks with her father, Mami is approached by Homura, who warns her about making Madoka a Puella Magi. The next day while visiting the hospital, Madoka and Sayaka find a Grief Seed that is close to activating, so Sayaka and Kyubey enter the portal ahead of them whilst Madoka finds Mami. As Madoka and Mami catch up with them, Homura tries to warn Mami about the witch, but Mami binds her to stop her from following them. As they continue, Madoka mentions her wish is to simply be a Puella Magi and help others. Mami laments that her job as a magical girl has left her lonely and afraid, but feels happy that Madoka wishes to fight alongside her. As the Grief Seed activates, Mami goes into action and starts to fight against the witch. However, the witch suddenly transforms into a huge caterpiller which kills Mami. Homura, her bonds dissolving with Mami's demise, steps in and defeats the witch, claiming the Grief Seed, leaving behind a mortified Madoka and Sayaka.
