The Error in Creation: A Reincarnator Who Defied the Laws of Magic

Raika is a girl who grew up without warmth from her family, living in neglect and starvation until she eventually died. She was then reincarnated into another world filled with magic, monsters, and medieval kingdoms, where she was given a chance to start a new life. However, Raika has no mana, something that should make magic impossible. Yet, she is still able to use magic which broke the laws of the world.
