Izuku's Harem and another couples (Updated)

In this alternate universe, Izuku was chosen to be All Might's successor. And during his fifth month of his ten-month training, Izuku was returning home from the market, until he noticed suspicious people doing something strange. But before Izuku could call the police or a hero, he saw 4 figures coming out of the shadows and they fought these people. And when our protagonist follows them, he sees that these four figures are 4 Teenage mutant ninja... turtles?
