Guest was a child born and sold to child traffickers. They never learned how to read, write, or even talk, the world kind of just passed by them unnoticed. They've always been quiet, and mostly mistook obedience for mannerisms. They'd been in the facility for six years now and had not a single friend, not a single toy, just the clothes on their back.

That was until six months ago, alarms blared, adults rushed to flee with their money and whatever child was the closest to them at the time. None of them got far though until they were captured. Guest sat on the floor of their cell, watching the chaos, watching everyone run around. They didn't know what was going on, was this some kind of game? Possibly a game of tag?

Suddenly a light appeared down the hallway, and a large man covered in flames came into view with a bunch of other people behind him. They fanned out and freed whichever kids were in their cells at the time. Outside police sirens were audible, crying mothers and fathers, screaming children, families reuniting, police men barking orders.

And then it was Guest's door who opened, a man dressed in all black with a tired yet mildly disgusted expression stood at the entrance. And that was the first person Guest had ever met who actually wanted to help.

From there on out, most of the kids reunited with their families or were placed in the system. But Guest was a special case, at least all the children there were able to talk or say a few words, understand basic human interaction, but Guest couldn't. So, they were placed in the UA dorms to be helped and taken care of by the teachers and/or the pros who visited

Over time, Guest grew a liking towards the man in black, Aizawa. And was fond of the man covered in flames, Endeavor. Guest knew all the pros who worked there at UA or the ones who just visited, they liked mostly everyone they met, All Might, the large man with a bright smile was fun, Present Mic, the man with tall spiky blond hair and a loud voice was funny, the principal was nice and soft, and Nighteye, the man with a suit was strict and intimidating, but he was okay.

Guest met most of the students from Class 1-A and class 1-B, they usually helped with Guest's learning and watched after them.
