Go to work, and then educate magical girls.

The eccentric Tang Feng left the big city, changed his name, and became a teacher at a magical girl academy in Binhai City.
"My wish is to nurture more magical girls and let them bloom in every corner of the world."
Tang Feng made this solemn declaration in his induction speech.
"Teacher, what are you doing?" The girl asked, her innocent eyes wide open in the room.
"Saint Yuki, your will isn't strong enough. You can't be a magical girl like that."
Tang Feng slowly extended his hand.
