Found by the Woods

Three years ago, because she was born without magic, the half-blood baby Aria was cruelly abandoned in the Forbidden Forest by her grandfather, Duke Valerius, who valued "pure blood" above all else. Three years later, Aria—raised by an old witch—returns to the royal capital to find her birth mother, wielding "ancient spirit-speech magic" that makes every word she speaks come true and crushes everything in its path. Facing enemies wielding dark magic, a grand archmage summoning frost dragons, and an ultimate villain attempting to devour the world with the Abyss, three-year-old Aria clutches her old teddy bear and casts the most terrifying forbidden spells in the cutest, most childlike voice.

The grand archmage willingly drops to one knee to become her little sidekick; the arrogant villain is pressed into the dirt by a single finger; and her cold-blooded grandfather who once abandoned her ultimately sacrifices all his magic and his life to save her, consumed by endless regret. This is a god-tier underdog story of an invincible three-year-old cutie saving the world and fiercely protecting her mother.
