The Three Villain Brothers and Sisters

Mia traveled through books, into the magical world of the steam age, and became the biological sister of the villains. Looking up - The seventeen-year-old eldest brother Kane, a manic demon king who will be stabbed through the heart by the protagonist in the future, is breaking his wand in two to vent his anger. The smell of dark magic is so frightening that the house elf is trembling. The sixteen-year-old second sister Cecilina, a genius frost witch who will be sealed in the future, is carving a skull with ice edges, and the coldness of her fingertips causes the crystal chandelier to fog up. Thirteen-year-old Mia, the only Muggle in the family who did not know magic, eventually died in a battle launched by the Holy Knights against the dark magic family. It is written in the book that her brother and sister will go completely crazy after her death, start a bloody war in the magic world, and finally be annihilated by the righteous protagonist group. Mia: QAQ is already in the book, can't you let me live longer? ! What she didn't know was that her brothers and sisters could clearly hear her voice. When the eldest brother wants to chase away the little witch who accidentally breaks into the castle—— Mia's inner OS: Brother TAT, stop it! That's the protagonist's sister! Kane suddenly loosened his grip on the little girl's collar and dusted her off. The little witch was at a loss, and then burst into tears. Kane: (raising his hands) I didn't hit you! When the second sister is about to deliver a fatal blow to the noble paladin—— Mia's inner OS: Sister, don't freeze him! Keep his skills useful and help you block fatal blows in the future! Cecilina's frozen fingertips paused. The arrogant knight, who looked forward to death, opened his eyes in surprise and stared at his old enemy in the distance. — One day, the protagonist "Son of Light" who saved the world in the original book suddenly visited. Mia (pupil earthquake): It's over, it's over! He is the male protagonist in the book! Why is he here? Didn't he say that he would kill my brother and sister after ten years? The eldest brother Kane looked wary, and the second sister Cecilina had frost on her fingertips. The young man opposite had a cold silver hair and a clear voice, "The day before yesterday, my little sister accidentally broke into the forbidden area. Thanks to Master Kane for saving her, I came here to express my thanks." Mia (internally screaming): Wow his eyes are light gold! What a stunningly beautiful boy! Kane rolled his eyes, and Cecilina turned around and left. The young man looked slightly startled: Did someone speak just now? Later—— The manic big brother Kane was helpless in front of the weak and crying little witch: "Stop crying, can I stand and let you fight?" The cold second sister Cecilina, when the proud knight blocked the curse for her, sneered with red eyes: "Idiot, is it worth dying for your old enemy?" But Mia thought she had "worked hard" to reach adulthood. Looking at the cold protagonist who should have killed her whole family, she handed her a bouquet of roses stained with morning dew. Intention: Live an active life and make progress every day
