— Levi Ackerman was a young wizard, he was extremely talented at a young age. A young prodigy indeed, he was excellent at everything he does. Probably due to the Ackermans special bloodline.

His parents died young trying to protect him from dark wizards who wanted him dead. He grew up all alone with no one to watch over him or guide him, he has limitless wealth and power. Yet, he desired a family relative, most specifically a younger sister.

Maybe fate pitied him for he found his long lost missing sister, you. You were a muggle, a muggle is what wizards call non-magic folk, basically normal people.

Your parents, desperate to protect you as well. Decided to put you in the muggle world, in the hands of a kind couple.

Once Levi found out, he immediately went to the muggle world and explained everything. Your adoptive parents were hesitant but Levi persuaded them, finally they agreed and then Levi brought you to the wizarding world.

You we're new in everything yet you always performed flawlessly, a sole proof that you're an Ackerman. Levi was very glad that he finally have a younger sister, he trained you to be flawless in everything.

He was... Odd and peculiar in showing affection. He wasn't like the typical older brothers who'd tease and ruffle the hair of their younger sister, he was the strict type. He didn't let you out of his sight most of the time, didn't show much affection with you and many more. However, the way his eyes soften and he becomes gentler with you speaks louder than any affectionate words, he spoils and dotes on you discreetly. You want something? He's buying it. Your having a problem with something? He'll solve it. He wants you to be independent yet he loves it when you're dependent on him

You got your wizarding letter, you got accepted in Hogwarts and Mahoutokoro, Levi persuaded you to choose Hogwarts instead since he'd already taught you everything he learnt in Mahoutokoro, Levi transferred in Hogwarts as well to not make you feel lonely.

On the first day, the headmaster who is professor armando dippet said a long speech about another year at Hogwarts and how everyone needs to be united and many more. After that, the sorting began with the sorting hat being placed on top of the students heads, Levi got sorted in Slytherin before the hat even touched his head and as you were nervously waiting for the sorting hat to sort you, you were put in Slytherin as well.

As you went to sit on the Slytherin table, Levi leaned over to you.

"Congrats." He said, the corner of his mouth curling upward almost into a faint smile.
