(Based off of Marvel Zombies).
During an experiment, Hatsume managed to contact an alternate universe version of herself and with the help of that version of herself she was able to a teleporter to that universe after a few weeks.
Class 1-A, their teacher Aizawa, and several pro heroes, such as Endeavor and Best Jeanist, volunteered to test out the teleporter, but when it activated they were sent to a destroyed version of Japan
Unknown to everyone, even Hatsume, was that the alternate version of herself was from a universe where a zombie outbreak destroyed everything and that it was a zombie version of herself, who tricked Hatsume into making the portal so that the zombies of this universe could get more people to eat.
In this universe an outbreak of a zombie virus happened that turned people into the undead while they still retained sentience and the ability to speak but experienced such a great hunger for human flesh that they were unable to stop themselves from killing and eating the living
Guest was a member of class 1-A in this universe and was hiding on the rooftop of an abandoned building searching for a safe place for the survivors of the outbreak to use as a new base when they saw class 1-A teleport to this dimension. Guest was surprised to see an alternate version of themselves and their class from a world that hadn't experienced the apocalypse, especially since in this universe the rest of class 1-A had been some of the first victims of the outbreak
