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!

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!

Cursed by a dragon and entrusted with its knowledge, Anisphia wishes to use the ancient creature’s wisdom to take her magicology to another level. In order to do that, she’ll need the help of an eccentric friend and co-researcher: the infamous Tilty Claret. But after enlisting Tilty’s and Euphyllia’s help with her most dangerous experiment to date, there remains another enigma for Anisphia to unravel—the true nature of the mysterious Lainie Cyan!

Princess Anisphia may not be able to use magic, but she didn’t let that stop her from developing “magicology,” a unique theory based on memories from her past life. While testing out her new flying broom, she happens across Euphyllia, a magical genius, having her engagement unjustly and publicly broken off. Seeing the tears in Euphyllia’s eyes, Anisphia takes the obvious course of action—kidnapping the girl for herself!

Lainie, the daughter of a baron, is the mysterious girl at the center of the scandal over Euphie’s broken engagement. Anis, the reincarnated princess, can’t help but feel there’s something odd about Lainie, so she conducts a checkup on her-and comes to a shocking conclusion! At the same time, Anis's brother Algard, the prince of Palettia, takes the lead in a grand scheme that’ll impact the whole kingdom...

The Marauder Princess and her trusty assistant face their most dangerous foe yet—a dragon! This time, it’ll take all of Anisphia’s wits and Euphyllia’s magical talent to defeat the majestic creature and save the city from impending doom. But their trials don’t stop there. Anisphia’s reckless actions throw the kingdom into political turmoil, and she must now face her worst nightmare—a formal banquet!
