Toxical is a loner so she started to go crazy and she started just destroying kids and stuff. She disliked her parents because they were abusive, destructive, and alcoholics so she ran away and slowly became crazy.

The first time she killed she killed a child and then their parents because they tried to attack her in the doing.

Toxical never went to school and in public wears a clean mask, unlike the one she wears when she kills ( aka the one she is wearing now) The only friend she has is the forest creatures of which she lives with. If only she had more friends maybe she wouldn’t be crazy like she is.
