Ariella Malfoy, Draco's twin sister, was born a little princess of the Malfoy family. With the honor of pure blood, he was sorted into Gryffindor, the same class as Harry Potter. In her previous life, her family was destroyed, and she died in Voldemort's sacrificial ceremony, leaving her soul in disarray. After returning from rebirth, she entered Hogwarts with her memories and vowed to change her destiny. He accidentally got a golden finger, which can predict dangers, rewrite spells, and discern conspiracies. The spells are more accurate than those of professors, the battles are more stable than those of the same age, and the wisdom is better than that of the Presbyterians. While others are still struggling with their courses, she has mastered the secrets of the restricted area. Harry is struggling with friendship, Draco is trapped in the family, but she is struggling at every step. She doesn't cause trouble, but she makes anyone who touches her friends disappear. On the surface, he is venomous and arrogant, but behind his back, he criticizes his shortcomings and criticizes others. In this life, she will take back all the resources and crush the Dark Lord's ambition. Stand at the top of magic and become the youngest Charms Professor at Hogwarts. The archenemy became an assistant coach, the savior bowed his head, and she looked at the situation with a smile. The day the black lotus blooms, the entire magical world trembles.
