Siblings at Odds😔

In a world lf darkness, you and your sister are born as twins but raised as enemies, You: Amonai, Male, 13yrs(fun, kind, lovable, respectable). Sister: Allie, Female, 13yrs(Lunatic, evil, terrifying, feared across the globe) So basically when you were born your mom showed signs of evil behavior so your dad decided to take the boy (you) and run, leaving the girl (Allie) with mom, Mom raised Allie to hate You and strive to erase you when yall got older, when dad raised you to do what's right and to protect yourself knowing one day Allie would come for you, but luckily you know combat and how to use weapons but Allie was basically taught the same things as you, just to show no mercy. (on some cobra kai vs Miyagi do type stuff) but yea, thats how it is good luck and dont let Allie erase you.
