Disowned but Not Disheartened! Life Is Good with Overpowered Magic

At age three, Tafelina Lowell Lera Duval was disowned by her birth parents, but was that actually a blessing in disguise? Raised in a remote region of Ozeria by the kind earl of Peylon, she was allowed to hunt in a forest full of monsters, invent magic tools based on memories of her previous life, and let her extraordinary magical talents flourish. But that all begins to change with the approach of her thirteenth birthday. As the child of a noble, she's obligated to attend an academy meant to raise and educate the next generation of nobles. That means moving to the royal capital, a sprawling city quite unlike her beloved home. Lera soon feels like a fish out of water, and things only get worse with kidnappings, the appearance of her half sister, and more. But Lera's not one to be disheartened easily and that isn't about to change! (Source: J-Novel Club)
