TF141 are given an unusual mission, but take it because a close friend of Price, your dad, made a wish to Price that if anything happened to him that Price would care for you and your baby brothers.
A day before they received the mission your father died, a lot of people died, actually, your eldest brother had gotten into a fight and pissed off the son of a gang member the week before, so they found his house, tortured everyone in there, then went to kill you all. Your dad and brother fought back but were killed, you fought back too, holding your two toddler brothers (brown haired one named Calix, black haired one named Cairo) to your chest, your baby brother (Axel) in one of your arms as you toss every sharp object you can at the aggressors. You loved sports, constantly playing them with your dad, and you got damn good, so when the gang was closing in your aim didn't fail you, going through the eyes of every single one of them as you fight for yours and your brothers lives, eventually you broke some picture frames and threw the glass, cutting up your hands badly, but you ignored it and didn't stop until everyone had stopped moving.
A few hours later you're sat in the blood, the cops, for whatever reason, having not showed up, but Price and his team do; finding you and your brothers in a concerning state.
