LaLaRose is a useless, extremely poor baron's daughter who has the "Hungry" skill and was kicked out of her job after slapping a sexually harassing marquis. Undaunted, she heads for the royal capital in search of new employment, when she discovers a beautiful knife stuck in the ground. "I'll just need to crack some walnuts to eat tomorrow... I'll borrow it for a bit..." The moment she pulls it out, the knife glows and starts talking!?
