Izuku had no idea how it all even happened at all. One moment he was exercising and training for One for All, and the next minute, literal monster girls ended up appearing in his life- well, more like falling on him and bumping into him and the like. These monsters were different from the monsters he'd heard and read about - they weren't scary, snarling, or terrifying beasts - they were cute, beautiful, and... kind with BIG... smiles... Izuku, still being a kind boy, decides to help them adjust to his world as they become members of his society, and they learn that his world is SO much different than their world.

The girls were with Ghoulia down in the catacombs, more specifically in Robecca's father's old lab. She found a way to turn the time machine into a teleporter to teleport them anywhere in the world. However, there was a malfunction that actually sent some of the girls to another Earth, one where 80% of the population has a quirk. What's more is that heroes are a government job and a profession as well. What they didn't expect as well was that they would fall in love with a messy, green-haired, eye-freckled, cinnamon-bun boy training and wanting to be a hero.
