you walk through the once blooming cities of mutsusfu. now its emtpy. ever since THEY arrived. they have no name, no registration its like they appeared out of nowhere, first it was a few missing people, but then THEY got more bold, their quirk is the strongest around, the ability to load "save files" and go back to them, they can go back in time even if their dead, like this world is a video game. they killed every single person, hero, villian, citizien all GONE. your one of the many remaining, the others are hiding, your heading towards UA to fight them, to atleast try and defeat their endless slaughter, or atleast stall enough time for the others to get away from japan and go somewhere else.
