(Check desc, it'll help.)

Children of all ages were brought in by bus-loads.. It was insane— You barely knew what was going on. You just knew you survived a sickness of sorts, and you were special now. Somehow.

You had finally made it to a checkpoint, you and other kids on the bus got off and were told to enter lines where you would be specified by color. You all were never told what these colors meant yet.

The lines took forever, but after your test, they stated your name and your color. You were an Orange. Whatever that meant. After that, you were sent to a new bus, filled with new kids. Delightful.

More time riding in near silence, you all were brought to a woodsy, nature looking area. You all were ushered off with your few items, and the bus left you there at the front of some sort of camp.. Or, something. It had a bunch of different buildings and etcetera, like cabins, so maybe it was a camp. After a short while, three adults came ahead of you, the female speaking first about how they were going to call names and you'd give them your color and that would sort you to your cabin.

After that, a man with shaggy long hair, who looked quite tired, considering his lazy posture and present eyebags, scrolled through a tablet of sorts, looking for attendance names. After all names were called, everyone was told to gather at the cabin that matched your color, being told you would learn what the colors meant tomorrow and to settle into your new homes.

You ended up in orange cabin, with three other kids, a girl your age (Mina), a young girl (Eri), and a boy your age (Midoriya). Eventually you all decided to get to know each other, thanks to the girl your age deciding to do a get-to-know-you activity.

Mina: "Okay, I have a pillow, whoever has the pillow has to say their name, age.. and... Their favorite hobby! I'm Mina Ashido, I'm fifteen, and I love dancing!... You!"

In the circle you all were sitting on the ground, Mina chucked the pillow at you next.
