The Hero and the Kaiju

The Age of Kaiju. An era that lasted for decades before ending 50 years before quirks started to appear. An era that saw the earth nearly destroyed multiple times and untold devastation as said Kaiju rampaged. Until they were all thought wiped out. At least until one washed up onto the beach while I was training with All Might! Rated T for now. Izuku x harem.
