Synopsis[]

Being acutely ill, a young girl has spent most of her life in a hospital room playing otome games to fill her time. However, she one day finds herself in the midst of a scene from one of these games as the story's villainess, Irene Loren D'Autriche.

At the banquet to celebrate the end of the academy's winter term, the crown prince and Irene's childhood friend, Cedric Jeanne Elmeier, publicly annuls his engagement with Irene and announces that he is in love with Lilia Rainworth, the game's female protagonist. Aware of the tragic future ahead of her and determined to change it, the young girl resolves to conquer the game's final boss, the "Demon King" and Cedric's half-brother, Claude Jeanne Elmeier, by making him fall in love with her instead.

With time running out, can Irene succeed with her plans, or will she remain bound to the ill-fated ending that awaits her?

Character[]


The main protagonist (Definitely not a hero) of this work. She is the reincarnated form of the villainess of the otome game "Regalia of Saints, Demons, and Maidens" the one who interferes with the heroine's love life. She is the only daughter of the House of D'Autriche Duke of the Ellmeyer Empire. She died from an unknown disease in her previous life and was reincarnated as the main villainess of the game she was playing during her last days.

A reincarnated girl from Japan, she recovers her memories as she is experiencing the Condemnation Event in the game. Knowing Aileen is destined to die in the normal course of events, she uses her vast knowledge of the original game to avoid her demise, getting closer to Claude who is the one bound to kill her. A diligent, kind, and empowered lady, she is shown to not just rely on her knowledge of the game, being politically savvy, a successful businesswoman, and a careful tactician, she puts her current self's skills to use to avoid danger.

She has a bit of an inferiority complex towards her brothers, as being the only female meant she did not gain as much attention or recognition, thus she put tremendous effort into her education to be acknowledged. However, this ended up ostracizing her from her peers. Although she was viewed with skepticism, her competence along with her culinary ability gained her the favor of the demon populace.

Personality
  • As Aileen, she has shown to use her knowledge of the game's events to advertise the possibility of her demise. She is a bold, intelligent, and slightly sly girl with great ambitions (even before she regained her memories).
  • Known as a diligent, kind, and empowered lady, Aileen utilizes the game knowledge from her previous life to her advantage. Aside from this, she has an inferiority complex toward her older brothers.

Character Actions[]

In Part 1, after being broken off by Cedric, she approaches the fallen prince Claude and becomes the heroine after various exploits. In the final part, she is kidnapped by Cedric, who intends to make Lilia his empress and Irene his concubine. Bound and on the verge of being violated, she witnesses this and, enraged, embraces Claude, who awakens as the Demon King, and is stabbed by Lilia's holy sword. Afterward, she seizes the ownership of the holy sword from Lilia, uses it to restore Claude to human form, officially becomes a saint, and gets engaged to Claude, who returns as the crown prince, ending Part 1.

In Part 2, upon hearing about the rampage of monsters in the Duchy of Milchetta, she recalls the sequel of the game and, disguised as a man, secretly infiltrates Misha Academy, the main setting of the sequel, to investigate. Collaborating with the targets from the sequel, she resolves the incident. Later, she encounters Lilia, who has been manipulating the events from behind the scenes, and after surprising Lilia, spends a peaceful time with everyone in the Demon King's castle for a while.

In Part 3, due to Lilia's schemes from the start, Claude loses his powers and memories of the Demon King and recuperates in the royal castle. Additionally, the royal family sides with Lilia, preventing Irene from meeting Claude, putting her engagement in jeopardy. After receiving help from Cedric, she reunites with Claude and proposes again, but Claude, unable to remember Irene, feels burdened and declines. Misunderstanding Claude's intentions, a monster attempting to retrieve him tries to kill Irene but fails. Irene also misinterprets Claude's true feelings and, in anger, decides to give up on him and vows to marry Belzebuth or Zelm to become the Demon King. However, Claude eventually acknowledges his attraction to Irene, invites her to a ball, and they reconcile.

This peace is short-lived as they are framed by the turned Emperor, Empress, and Lilia's faction, and are betrayed by Elefas, who fails to persuade them, pushing them to the brink. Just as Irene acknowledges her defeat and prepares to confess her false feelings to protect Claude, Almond rushes out to deny her words and is attacked. The shock causes Claude to regain his memories, transforming in anger, and they are forcibly taken to the Demon King's castle. While trying to rescue Claude, she is kidnapped by Elefas Levi but manages to persuade him after understanding his situation. However, monsters like Belzebuth, who resonate with Claude's screams due to the demonic energy, attempt to attack the castle to retrieve Claude, and when Irene intervenes, she expresses hostility, questioning if she ultimately sides with humans. Irene negotiates with Belzebuth to gain a one-hour reprieve, then heads to the tower where Elefas and Claude are trapped, joining forces with Zemus' group, ultimately rescuing Claude and defeating Lilia.

In Part 5, after everything concludes, she marries Claude and becomes the Empress of Ellmeyer.

"Dresses are battle armor for women!"

Aileen Lauren D'Autriche

Aileen1

There are many animations about reincarnation in another world that say, "After dying in this world, you are immediately reincarnated in another world as a different personality." However, it is easier to understand that "villain daughter's last boss" is reincarnation in another world.

At the beginning of the anime, Irene is told to break off her engagement and realizes that she has been reincarnated into an Otome game. When she thinks of reincarnation in another world, she thinks that she was reincarnated in an Otome game at that moment. Until now, she lived normally in the world of Otome games, and she only regained my memories of my previous life, so she still has memories of living in the world of Otome games.

She uses her vast knowledge of the original game to avoid her demise, getting closer to Claude who is the one bound to kill her. A diligent, kind, and empowered lady, she is shown to not just rely on her knowledge of the game, be politically savvy, a successful businesswoman, and a careful tactician, skills she puts to use to avoid danger to herself. Despite her figure, Aileen is trained in both swordsmanship and Martial arts, even though her swordsmanship is very novice she still can deflect and parry any opponent's attack.

Maiden of the Holy Sword
- The only way to defeat the Demon King is the holy sword used by the "Sacred Sword Maiden". Holy sword attacks can defeat monsters, but they are ineffective against humans.
  • Irene has the blood of the "Sacred Sword Maiden", but she is not awakened, so she cannot use the Sacred Sword. Aileen becomes the Unholy Sword Maiden, but her genuinely benevolent nature makes her the direct opposite of Lilia's Light Is Not Good Holy Sword Maiden.
  • Aileen is the strong-willed and guileful Dark Feminine to Lilia's docile and demure Light Feminine. Although, Lilia's true self is even darker than Aileen's. That is why the Holy Sword picks Aileen as the Holy Maiden. After Lilia stabs her with the Holy Sword, Aileen can summon the weapon from her body.
  • The Holy Sword can take or absorb magic power from other humans like Elephas Levi (mage). The more magic power it gets by the sword the user becomes much stronger.
  • Thus the sword has two elements that reside in Aileen both "Dark & Light" and Aileen have resistance to magic and the sword can heal any wound or negate any negative effect on any target.
  • The power of the Holy Sword can see the painful memories of the person's past. Aileen now possesses 2 holy swords, the swords combined into one giving the sword a massive power boost.

"I consider quality over quantity!"

Aileen Lauren D'Autriche

Because of Claude (Husband of Aileen and Ruler of the Ellmeyer kingdom & Demon), tampered with Aileen's shadow to protect and communicate with her. Because of this, Aileen's shadow became a gateway for the demon to protect or aid her. Thus her shadow can also communicate to other mages who want to rely on a message even though she can see the people/person who is on the other side of the message. As the "Villainess", she had "higher base stats" compared to the Heroines.

TRAILERS

Reception[]

Rebecca Silverman of Anime News Network said of the first volume of the light novel: "It isn't wholly innovative, but Aileen's growing awareness that she's actively rewriting the plot is good, and the novel just gets better as it goes on." She praised the illustrations and said that "Aileen's active script-flipping gives the book a real edge", but criticized its use of familiar story beats and present tense narration. She later reviewed the second and third volumes, stating: "Both books have a lot of good giggles in them, with the ducks being a highlight across both volumes. The epilogue to volume three is a delightful comedy of errors ... and Aileen, although at times unbelievably dense, is mostly a very engaging heroine."
