Puella Magi Madoka Magica (2011)

S1E4 Miracles and Magic Are Real

The day following Mami's intense clash with the witch passed quietly and uneventfully. Having seen what they saw, Madoka and Sayaka finally grasp just how much is truly required of anyone who enters the magical world. With that understanding weighing on them, they decide to abandon the idea of becoming magical girls themselves.
