Although born to a small, noble family in the countryside, Anna, the daughter of a baron, ends up attending the country's most prestigious school, the Trusova Magic Academy, at the request of her kind parents. She nearly loses her place in the school, which is a microcosm of the hierarchical society of the nobles, but her fate changes dramatically when she meets the graceful and beautiful young lady Rachel. Another story of time travel told from the perspective of Anna, who eventually becomes a "saint." (Source: KADOKAWA, translated)

She was once known for her powerful magic — the very reason she was chosen to be the crown prince's fiancée. But when a "saintess" appeared, fear of losing everything drove her to make desperate, reckless decisions. Accused of committing evil acts against the saintess, her engagement was broken off and she was exiled to a monastery. On her way into exile, she was ambushed by bandits... and killed. But death wasn't the end. When she opened her eyes, she had gone back three years into the past! Yet her body was now frail, and her magical power had all but vanished. This time, she resolves to choose a different path — to pursue happiness, even if it means breaking off the engagement herself. The twist? The crown prince refuses to let her go! And even more shocking... a mysterious dark spirit, one never before seen in this world, chooses her as its master!
