Tensei Shoujo no Rirekisho

A girl who was intelligent, physically capable, and considered exceptionally beautiful dies in a car accident and is reborn into a fantasy world filled with swords and magic. She retains her past memories and finds herself in a world where life depends on magicians, whose numbers are dwindling as magic power depletes. As reliance on magic fades, the girl uses her knowledge from her previous life to suggest a way of living without it. She seeks to understand the nature of magic and improve her circumstances, aiming for a more prosperous existence.
