A RIFT IN THE ROYAL FAMILY! With the help of her assistant—the genius young lady Euphyllia—Princess Anisphia has successfully subdued the dragon that attacked the Kingdom of Palettia. Nonetheless, the furor over Euphyllia’s canceled betrothal continues. To make matters worse, Anisphia discovers a devastating secret about Lainie, who holds the key to the prince’s strange decision. And that’s not the only secret—it’s just the beginning of a grand plot enveloping the entire royal palace!

Despite her supposed ineptitude with regular magic, Princess Anisphia defies the aristocracy’s expectations by developing “magicology,” a unique magical theory based on memories from her past life. One day, she witnesses the brilliant noblewoman Euphyllia unjustly stripped of her title as the kingdom’s next monarch. That’s when Anisphia concocts a plan to help Euphyllia regain her good name-which somehow involves them living together and researching magic! Little do these two ladies know, however, that their chance encounter will alter not only their own futures, but those of the kingdom...and the entire world!

Some time off at the royal villa has helped Euphyllia get her thoughts together following the shock of her engagement being broken off, but that clarity has only made her aware of how empty her heart now is. She looks to Anisphia for answers, but the princess is too busy getting hyped for an impending monster stampede! All high-ranked adventurers have been summoned to stop it, including the one known as… the Marauder Princess!

When Anis and Euphie learn that vampires are threatening the Kingdom of Palettia, they scramble to formulate countermeasures. Then, an urgent message comes from the East, stating that a vampire has been captured-a powerful one with great ambitions!

There’s one thing Anis can't go without if she wants to run a magical academy—magicite. Fortunately, an untamed region to the east is teeming with this vital resource, so she and Euphie decide to journey there on airbikes to stock up. Wait, doesn’t this sound like a honeymoon?!

Anisphia becomes the ruler of Palettia, but her fight with her younger brother, Algard, has caused all sorts of problems. Watching Anisphia slowly become more and more exhausted, Euphyllia finally decides to step in. But that is the last thing Anisphia wants, and she refuses to give up. The reincarnated princess and the genius young lady now have to face each other for their future together.

After receiving the right to succession, Euphyllia is facing a future where she becomes ruler, while Anisphia is released from her obligations and continues her research. How will this affect the future of Palettia—and Anis and Euphie’s blossoming relationship?
