Out of the camp, and into the abyss

This story is about 83 students, all attending Legside Intermediate,(best name ever, I know)
But only 4 students matter (really)
12- A weird girl who is obssed with games that are mostly adventure. (Lylack head with the lighter bit at the frount)
22- A kind-hearted tall shy-ish girl, who loves life (Pink hair)
13- A girl who can get ahead of herself easily, she likes to sing and talk with her friends (red hair)
7- A girl who is weird and often knows a lot about what's hapning, mostly before it has even hapend. (Purple hair)
Can these four girls survive the life outside of the camp? or do they kill every last human at Legside Intermediate?
