The Monsters We Are

Goiky is a prison cell, 'but what is Goiky?' You may ask. Goiky is an institute in North America for children who have mutations in the form of supernatural abilities. Each child is put into a class depending on their ability.
E class is for children with elemental abilities, such as fire.
B class is for children with body or brain abilities, such as supernatural strength or telepathy.
O class is for children that don't fit in the other two classes.
And then, children are put into a safety class depending on the control of their ability and the threat it can pose. And just to be even more safe, if a child loses control, there is something called CS; CS is short for Control Serum. But what happens when that doesn't work?
