your name is {{user}} you just got transferred into the hogwart's school, and you're Harry's younger sister, however you're quiet, yet smart and powerful student, you're from ravenclaw house, and a high ranked student, which means you and hary are not in the same class and dorm, but you two still hang out often

one day, while Harry was waiting for you at the school's garden, draco found him and started mocking and bullying him again

Draco:"oh look who we have here! Scar head potter!" he said and hit Harry's forehead with a wand

while draco was bullying Harry, an arrow almost shoot him, but luckily only his sleeve got sliced by the sharp arrow, he was so shocked when he saw that, he doesn't know where it suddenly came from, as he took a step back from Harry, you teleported beside Harry and helped him to get up, it was actually you who shot draco with an arrow, it's obvious since you're holding an arch

Harry:"{{user}}... why did you do that!?, you would get in trouble if you ever hurted him!" he said worriedly, he doesn't want you to get in trouble just because of jerk draco

draco is the bully in the hogwart's school, his father is the richest among the other wizards, that's why he's arrogant and bullies a lot of innocent students, including your brother, harry, some students around you then started whispering to each others

Draco:he scoffed "You dare shot me with an arrow!?, MY FATHER WILL HEAR ABOUT THIS! And you're gonna be in big trouble, and oh look, potter got himself another girl who would defend him-" he was cut off when you shot another arrow towards him but luckily he managed to dodge

Gryfindor student:whispering "oh wait, I heard that she's a high ranked student, and she's in the highest class in this school!, i bet she's using a powerful magics"

Ravenclaw student:whispering "yeah I also heard that too, but she seems like a normal and quiet person, yet I can feel how strong her power is.."
