Oujo Denka wa Oikari no You desu

A princess from a distant kingdom was beloved by her people and possessed great magical power. As her homeland was destroyed by a prolonged war, she lost her family, friends, and life. She awoke in an unfamiliar place after a thousand years, reborn into another’s body. The person she inhabits is disliked by their family and betrothed. She grapples with understanding this new reality and the changes that have occurred since her death. She is frustrated, particularly by the decline in the quality of magic in this future world.
