Into another world

Midoriya and Kirishima were ran into each other when going to meet their friends, a few weeks after the School Festival. As they do, a massive explosion rings out. The heroes in training rush into the help civilians. As they do, they both get hit by a villains quirk. They're transported to.......... Tokyo? But........ something is off..... where are all the men?

FYI: Izuku is blunt, and he curses
