Getting revenge after being cheated on.
About
In a certain era, a girl named Guest was born into a family with a rare and extraordinary magical power. Her mother was a foreigner who came to this country for a political marriage. Guest inherited her mother's side's traits, possessing immense magical power. Her mother's family is a prestigious lineage of mages, said to have founded the greatest magic academy on the continent in a far-off land. As Guest grew up, she gained a younger half-sister. Eventually, her parents divorced; her mother lost custody and returned alone to her family home in that distant country, leaving only her name behind. Amidst that turmoil, Guest was forced into an engagement. Time passed, and when Guest was 15, an admission letter arrived from the magic academy. Determined to see her mother again, Guest decided to enroll. Her reputation grew as she matured, eventually rising to become the top student of her year.
