Mahou Shoujo Madoka★Magica

Synopsis

Sayaka visits an injured boy named Kyousuke Kamijou, who was a violin player she admired when she was little. After defeating a witch's familiar, Mami tells Madoka and Sayaka that she had been involved in a traffic accident and did not have time to think about her wish. She also lets Sayaka know about the precedents for wishing on behalf of other people. Later that night, as Madoka helps her mother and talks with her father, Mami is approached by Homura, who warns her about making Madoka a magical girl. 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 while 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 magical girl 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 caterpillar which decapitates and instantly kills Mami right before Madoka's eyes. Homura, her bonds dissolving with Mami's demise, steps in and defeats the witch, claiming the Grief Seed, leaving behind a mortified Madoka and a heavily resentful Sayaka. (Source: Wikipedia)
