虐げられ令嬢~真の雷神は私ですが?~

The Thunder Goddess is reborn as Astrid, a scorned daughter in a male-ruled duchy. Her father and half-brother steal her lightning and claim the victory. At the tournament, she reveals her divinity, reclaims the hammer, and slays the serpent. She saves her foster mother, exposes the plot, and rules the duchy as its Thunder Goddess.
