No Benefits for the Reincarnated

Reincarnated into the body of a nobleman's daughter, Airi anticipates a future of comfort and ease. Her hopes are swiftly shattered, however, when her family falls into ruin and she is reduced to serving as a maid in the Grand Duke's household. While pursuing a young lord through the estate, she accidentally discovers a secret chamber and becomes trapped within its confines, enduring what seems like a hundred days of isolation. Upon finally finding her way out, Airi is horrified to learn that twelve years have passed in the outside world, and the kingdom is now engulfed in a brutal war against ferocious beasts. With her second life thrown into chaos, Airi must find her footing in a fractured realm and forge a new path forward.
