Make Magical Girls Great Again

This world is very strange, there are magical girls, and what is even stranger is that the magic comes from their strong twisted emotions. With their terrible personalities, they have become a taboo in the world, making people fear and hate them. The time-traveling self, Justice, just wants to live peacefully with my sister. But why should even such a wish be taken away? When I saw that the house with thirteen years of loan left was easily destroyed by the magical girl, my justice collapsed. What made him even more devastated was that the only compensation he received was a magical girl's three-second handshake coupon. Killing all the magical girls left, with strong hatred, he awakened his ability - to become a magical girl. But the magic power of magical girls is not effective on humans, nor on magical girls. In desperation, I decided to deprive the magical girl of her twisted emotions. That's what he thought! But why did he become the president of the "Magical Girl Management Association (MAGA)"? How about becoming "the man who makes magical girls great again"? I just deprived them of their twisted emotions... Who would have thought that they would fall in love with him!
