Big Brothers, Stop Spoiling Her! Your Mystical Little Sister Is Seriously Tough!

A brilliant little girl with countless secret identities returns to her family as soon as she comes down from the mountain.

She not only gains five powerful uncles, but also gets eight overprotective brothers who dote on their little sister.

At first, her youngest uncle wears a look of disdain. "She must be one of those annoying little brats that people and dogs can't stand. Girls are the worst."

Eldest brother: "I'm a strapping man. I don't want some delicate, helpless little sister. If you want to be my sister, prove you can beat me first."

Second brother: "To be my sister, you must excel at music, chess, calligraphy, and painting. Otherwise, you're not worthy!"

Third brother: "Do you know military strategy or mechanisms? If not, get lost."

Seventh brother: "I'm the one who brought our sister home. If you won't dote on her, I will!"

Later:

Eldest brother: "My sister is unrivaled in martial arts. Can you do that?"

Second brother: "My sister can draw talismans, tell fortunes, and catch ghosts. Can you?"

Third brother: "My sister can act cute, play adorable, and throw tantrums. Can you?"

Seventh brother: "All of you, move aside. My sister is mine!"
