Sasara is inside a witch labyrinth, reminiscing about how she made a contract with Kyubey. One day, she feels empty because people forget that she's saved them and she never gets thanked. Sasara later meets another magical girl, Tatsuki Asuka, and even though they both have different goals in a battle, they manage to destroy the witch together. They then join forces, as the battle was a success. Sasara finally feels whole again. Her battle goal was now to rescue and protect people while Asuka kills the witch.
