Hildegart Reincarnate

As the best arcane swordsman, Hildegart's feats made House Acaraxia the greatest noble family in the empire, amassing both wealth and prestige. But after being tasked with sealing away the Demon God, Hildegart was forced to sacrifice her life. In a twist of fate, she wakes up in the body of her 12-year-old great-great-grandniece 80 years later, where, much to her shock, her family has fallen into total ruin. Can the reincarnation of the first Hildegart restore her family to its former glory?
