After Class, Become a Magical Girl

Gu Ming, whose current occupation is a high school physical education teacher, his former occupation was a witch, and his previous occupation was a magical girl. He originally thought he could spend the rest of his life in this job, but one day he discovered that his student had become a magical girl. However—— Magical girls are a road of no return. All miracles and magic will eventually give way to darkness and pain. Gu Ming firmly believes in this, because he is the one who returned from the end, losing all fighting spirit, leaving only the witch with spreading despair. But he also questioned this, because he didn't believe that fate could defeat him or others. "Now, physical education class is over." "The next lesson is how to become the strongest magical girl in the world."
