Zeitakuzanmai Shitai no desu! Tenseishita no ni Binbou nante Yurusenai node, Mahou de Ryouchi Kaikaku

On Celestia's fifth birthday, a blow to her head brings back memories of her past life, in which she was very poor... And now, she also realized that she had been reborn as the daughter of the villian of an otome game!! Since she was poor in her previous life, she might as well take advantage of being reborn into wealth, and indulge in luxury! Or so she thought, but wait... the workers and villagers are all skin and bones, and on the verge of dying of starvation?! She can't allow people to be poor, especially since she knows what that was like from her past life!! So she decides to use magic to reform the land and bring wealth to both the villagers and herself! Source: Earth Star
