Madoka Magica Portable - Sayaka's Route Bad End ~ Homura & Madoka vs Walpurgis

After Kyoko and Sayaka's deaths, Madoka locks herself in her room. Homura eventually gets her out of it, saying that they're going to defeat Walpurgis themselves. They train themselves thoroughly, but when Walpurgis comes, they are soundly beaten by it. Madoka's Soul Gem has gone completely corrupt from the attempt at defeating her, and she asks Homura to destroy it because she doesn't want to turn into a witch. Homura complies and shoots it. She says she will not let it end like this next time, and resets the timeline.
