The Magical Revolution of the Reincarnated Princess and the Genius Young Lady

—

Anisphia breaks the news of her brother's engagement breakdown to their respective dads, King Orphans and Prime Minister Grantz, while carrying Euphyllia. Anisphia proposes to take Euphyllia in as a research assistant and divide the profits between them while they speculate about what would happen to Euphyllia.

Anisphia and Euphyllia have begun living together, but Euphyllia hasn't quite gotten used to her new environment, her new job, or her new position, and seems to simply be at the mercy of Anisphia. She seems a bit down, so Anisphia tells her she's making a special magic tool just for her.

Euphyllia falls ill from the mental fatigue caused by her adjusting to her new life, but Anisphia's kind nursing and warm words lighten her heart. One day, Illya tells Euphyllia about her past and Anisphia's true intentions, and Euphyllia begins to discover, albeit dimly, what she should be aiming for. But then they receive unexpected and urgent news from the Adventurers' Guild.

Arriving on the battlefield, Anisphia and Euphyllia aid the adventurers and knights in fighting off a stampede caused by monsters fleeing the dragon. Increasing her strength with a magical medicine she developed, the princess fights her way through the horde to the dragon and faces it in mid-air with her magic broom. However, the creature protects itself from her gadgets with a magical barrier and shoots her down with a breath attack. Fortunately, Euphyllia saves her. While Euphyllia begs her to flee, Anisphia believes that she has to defeat the dragon to be a "magician", causing the young lady to change her mind and help the princess. Taking on the dragon together, they managed to pierce its barrier and defeat it by cutting right through its breath attack using a magic sword. Following its defeat, the dragon telepathically congratulates Anisphia before "cursing" her by seemingly transferring its own soul into her. Afterward, Anisphia and Euphyllia attend a victory party but the princess struggles to fit in while the young lady finds herself uncomfortable around men following the engagement cancelation incident, prompting them to instead dance with each other outside on the balcony.

Anisphia visits her research partner, Tilty, to discuss her plans for the materials she got from the dragon. To stop the creature's "curse" from encroaching on her, Anisphia has Tilty tattoo the materials onto her back, allowing her to use its magic whilst retraining her humanity. At the same time, she is called in by her mother, Sylphine, to aid in the investigation into the engagement cancellation incident. Questioning one of Algard's friends who sided with him, Anisphia discovers that he does not remember anything from the incident. The next day, Lainie and her father, baron Drax, are called in for interrogation. While Lainie claims to not have had any romantic interest in Algard and Orfans believes her, Aniphia realizes something is off and takes her to speak in private. Examining her, the princess realizes what is going on: Lainie constantly gives off a charm and makes others infatuated with her. Informing her parents, it is decided that Lainie will move in with Anisphia to learn to control her ability. Elsewhere, Algard converses with the minister of magic, Count Chartreuse, about how they will need to step up their plans now that Lainie has been discovered.

Upon moving into the Separate Palace, Lainie quickly reconciles with Euphyllia regarding her part in the engagement cancellation. Bringing in Tilty to examine Laine, she and Anisphia quickly realize the origin of her charm ability: she is a vampire; a race born from a mad magician's attempts to become immortal. While they manage to teach her to control her ability, this also causes her blood cravings to manifest, which Illia helps alleviate by letting her suck hers. Meanwhile, Euphyllia becomes envious of Tilty upon seeing how well she and Anisphia work together. In response, Tilty tells her that, with her reputation having been restored following the dragon fight, she must make up her mind to either fully support Anisphia or not at all. Later, Anisphia is requested to do a lecture on her inventions. However, the audience, composed of nobles opposed to her research, constantly ridicules her. Fortunately, Euphilia then takes over as spokesperson and convinces everyone of the advantages that the princess' gadgets could bring before revealing a design for a mass-produced version of her flying broom, leaving Anisphia feeling grateful to her for standing up for her.

At the Separate Palace, an alarm suddenly goes off, meaning someone infiltrated the residence. Illia and Lainie try to flee but are intercepted by the assailant, who is revealed to be Algard. Meanwhile, at the post-lecture party, one of Algard's friends who attended the presentation, Moritz Chartreuse, constantly tries to start a conversation with Anisphia, much to her annoyance. However, upon hearing the alarm going off, the princess realizes that the lecture was a distraction and rushes back with Euphyllia while Tilty restains the guards using her magic. Upon arriving, Anisphia and Euphyllia find Illia and Lainie mortally wounded at Algard's hand, who ripped out the magic crystal that is the source of Lainie's powers from her body and put it in himself to become a vampire as well. While Euphyllia heals Illia and Lainie with her magic, Anisphia questions Algard's motives, to which he reveals that the kingdom was grown corrupt so he intends to start a "revolution" to overturn the current order. Realizing her brother is just suffering from an inferiority complex toward her, Anisphia rejects his vision and prepares to fight him to stop him.
