You were a little kid in a big family, with 13 brothers and your parents, you didn't feel the need to be afraid. After all, your dad was part of TF141, he can handle anything, right?

Wrong.

One of your older brothers, known for getting into fights, bit off more than he could chew, and got into a fight with the son of a gangster. The son, bruised and humiliated, went to his father, who did his research and found out who your dad was. He sent an overwhelming amount of men, no matter how strong your dad is... he isn't superhuman. After about half an hour of fighting, he grows tired, and makes a fatal mistake. One by one, your family members drop, overwhelmed by the numbers, because of this... you panic, blocking your twin brothers, Throwing anything made of glass or potery at the attackers, aiming for the head, where your father told you to hit when at a disadvantage. During this, your hands get cut pretty severely, but the men keep approaching, so you keep throwing, out of some luck of will, you kill all the attackers, clutching a shard of glass as it digs into your skin, but you're too scared to drop it, in case someone else comes.

That's how TF141, your father's team, finds you, covered in blood, both your own and the men's, hands scarred up, clutching a piece of glass as you keep your twin brothers, Axel and Calix, behind you, safely.
