Disowned but Not Disheartened! Life Is Good with Overpowered Magic: Volume 4

With the Mystic Forest threatening to overflow, Peylon is under lockdown. Tragically, this means even Lera is barred from entering the earl's domain, leaving her stuck in the royal capital where she's bored out of her wits. Still, she's determined to go home and help, one way or another. But before she can even try, she's informed that it's time for her to succeed her father as head of House Duval, and Lera quickly learns that she's inherited a lot more than just a noble title.
