I don't know if I'm gonna make it long and I'm not really gonna follow the plot, maybe a few scenes and plots. But you're the main character in this book. And if you want a one-shot with other bnha in the book or a separate one. There is gonna be a chapter in maybe every book I make from now on to where you deposit your requests, or private message if you want. Enjoy the story! Peace! X3

16th September; Day of the breakout. Monsters invaded the planet and killed more than one and half billion people. During the last ten years scientists discovered a new gene in the human body that allows one to use the most vigorous powers the earth provides. Only a few are able to develop those abilities. The governments of the world united and created a supernatural army in order to save the world from the monsters that plunged the world into chaos. The south korean government gathered all important figues of the country that are necessary to keep the national economy in balance. These people are brought to special bases of the army, built for the case of the current tragedy. They bring them to the place where the world's only defence against the monsters is training.
