is a Japanese light novel series by Ichiro Sakaki and illustrated by Yukinobu Azumi, also known as the popular adult dōjin artist Nakayohi Mogudan. In 2003, it was adapted into an anime series produced by Bones.

Scrapped Princess music was composed by Masumi Itō (pseudonym Hikaru Nanase), and its themes. It begins as high fantasy and then quickly mixes into varying degrees of post-apocalyptic and science fiction elements through the application of Clarke's third law. The atmosphere has undertones of sadness, though many of the characters and situations are superficially light-hearted.

Plot The story takes place in what appears to be a fantasy world and revolves around a girl named Pacifica Casull, the sister in a pair of twins born to the royal family of a kingdom called Leinwan. Pacifica is abandoned at birth. The 5111th Grendel Prophecy predicts that she is the "poison that will destroy the world" if she reaches her sixteenth birthday. To prevent this, she is dropped off a cliff as an infant ("scrapped").

Pacifica is rescued by a court wizard and adopted by the commoner Casull family. Her foster siblings, Shannon, a swordsman, and Raquel, a wizard, become her protectors. Both siblings are extremely powerful and, more often than not, they easily break out of whatever difficult situation they face. Her siblings travel with her throughout most of the story, protecting her from the numerous attempts on her life by people who fear the outcome of the prophecy. Both siblings' skills see constant use. By contrast, Pacifica is mostly a typical fifteen-year-old and her inability to defend herself is a recurring source of self-doubt for her, as is the constantly repeated insistence that she will destroy the world.

As the series unfolds, it becomes clear that this fantasy world is actually Earth in the distant future. The truth about the prophecy gradually emerges, but as we learn more, new questions keep popping up. Pacifica must discover her hidden destiny, as powerful beings called Peacemakers, who are worshipped in this world as demi-gods, continually manoeuvre to have her destroyed. At the same time, a mysterious being called a Dragoon comes to the aid of Pacifica and her guardians, offsetting the attack of the Peacemakers. It turns out that Pacifica is not "the poison that will destroy the world", but humanity's last hope, as part of a plan that was set in motion 5000 years before by scientists among the human resistance during what were called the Genesis Wars.

Before the Genesis Wars, the Peacemakers were created by humans as weapons against humanity's alien foes, but, determined to protect their human creators and prevent them from destroying themselves, the Peacemakers switched sides and assisted the aliens by imprisoning the survivors of the war in an artificial environment, while at the same time backing up their cultural development to the Middle Ages. The Peacemakers were able to do this with the help of a gifted psychic named Celia Mauser, who, like the Peacemakers themselves, had originally been a tool of the defense. Her powers were used to enhance humanity's weaponry, to the point where it was possible to predict enemy movements. The Peacemakers encouraged Celia Mauser to leak information to them in exchange for the lives of her brother and sister. She was too late; her siblings died, and Celia Mauser's treason was for nothing. Celia was then kept in an area of phase space in a sort of virtual reality for 5000 years, while humanity continued to live on unknowingly in an intangible cage, isolated on a single continent called Dusbin. Her powerful mind was programmed into the artificial environment's control system, and the religion concocted by the aliens to control humanity worships her as a god.

For 5000 years, the Peacemakers watched over humanity, keeping cultural development at a standstill, and prepared to wipe out much of the human race if it ever showed any sign of stepping beyond its apportioned limits (as the Kingdom of Leinwan does toward the end of the series when the attempt is made to coerce the Peacemakers into helping them conquer the world). As the Peacemakers put it, "You don't know you are trapped if all you've ever known is your cage." Humans are completely incapable of resisting the will of the Peacemakers. Just looking a Peacemaker in the eye renders a human obedient – even Shannon and Raquel are not immune to this. Pacifica is the only human being in 5000 years who is immune to this control, and her ability will become communicable to others once she reaches her sixteenth birthday. This is why the Peacemakers are determined to destroy her, and why they have used the Grendel Prophecies to induce others to do the job for them, since Pacifica cannot be directly attacked by the Peacemakers. In the end, Pacifica's twin brother, Prince Forsyth, who has seen the suffering inflicted on his people by the Peacemakers in their attempts to eliminate Pacifica, asks to meet her. Her guardians allow it and he uses the opportunity to stab her in the back, ten hours before she turns sixteen. This causes her to be removed to the phase sphere, where she meets Celia Mauser and is given the choice of whether humanity will remain in their prison or not. Pacifica chooses freedom.

Characters

Pacifica Casull

is the eponymous Scrapped Princess, who is prophesied to destroy the world of Providence on her sixteenth birthday. Her parents worried about her power and abandoned her when she was an infant, leaving her to be adopted by the Casull family. Pacifica is generally sweet and cheerful, but wonders how so much suffering can come from her existence and blames herself for it.

Pacifica is stabbed and killed by her biological twin brother, Prince Forsyth, before the prophecy can come to pass. She and her family are revealed to be the Providence Breaker, a group who would be able to resist the mind control of the Peacemakers and destroy the foundations of the system sealing in the humans to free mankind. After learning why Providence was created, Celia gives Pacifica the choice to determine humanity's future. Even though Pacifica is sympathetic to having a protected, ideal world to live in, she chooses instead to let humans make their own choices. As a result of this decision, Celia disappears and Providence is destroyed, freeing mankind once and for all. Pacifica is resurrected and returns to her family farm with Shannon, Raquel, and Zefiris.

Shannon Casull

is the son of Yuhma and Carol Casull, Raquel's younger brother and Pacifica's older foster brother. Shannon is a skilled swordsman who has sworn to defend Pacifica's life no matter what, but he is reserved and calm despite the many difficulties in the Casull siblings' lives. In episode 6 of the anime, Shannon becomes a temporary Dragon Knight ("D-Knight") and is capable of using the power of a Dragoon named Zefiris to fight the Peacemakers. Later in the series, he gives Zefiris his trust and fully merges with her.

Raquel Casull is the oldest of the Casull children, Shannon's sister and Pacifica's foster sister. She is a powerful magic-user and able to cast spells faster than many others. She has assumed a motherly role in the family and is always kind and calm. Despite her kind, calm and goofy nature, she will not hesitate to strike down anyone in her way of protecting Pacifica or Shannon. Raquel's normal kindness often serves as a cover for a more aggressive and tactical mind that asserts itself whenever Pacifica or Shannon are in danger.

Christopher Armalite

is the leader of the elite army unit Obstinate Arrow. He is an expert fighter and wields a large battle axe that can be folded and concealed. Ordered to eliminate the Scrapped Princess, he kidnaps Winia Chester to lay a trap for Pacifica's guardians. Shannon beats him in a duel in Glass Canyon and asks him to stay away in exchange for sparing his life. After the Baroness is dismissed from commanding Obstinate Arrow, the team serves under the Major. Christopher arrests Pacifica then, but later helps her escape. After Providence is 'destroyed' and mankind is freed, he marries Winia and becomes good friends with the Casulls, while maintaining his friendship with Prince Forsyth.

Winia Chester is an introverted and lonesome inn-maid, taken in and raised by her uncle out of pity after her parents died. She spends time with and becomes friends with Pacifica, and it is one of the few times she has smiled and laughed since her parents were killed. When Christopher kidnaps her and takes her to the Glass Canyon, Pacifica's identity as the Scrapped Princess is revealed to her. Although initially confused and unable to accept the fact that her new friend is "the poison that will destroy the world", Winia eventually comes around, and continues to have a close friendship with Pacifica.

Leopold Scorpus , also known as Leo, is a clumsy but well-meaning traveling lordling who wishes to become a noble knight. He joins the Casull siblings after discovering them being "harassed" by a group of bandits. Utterly charmed by Pacifica, he vows to protect her and one day marry her. As the first son of Duke Scorpus and heir to his father's territory, he begins as an idealistic youth seeking to join the order of Amber Knights. After meeting the retired legendary knight Doyle Barrett, he begins to question the meaning of justice and chivalry, setting his quest to knighthood in second priority until he can finally discover for himself what chivalry truly is.

Kidaf Gillot the Silencer is a bard who tries his luck as a bounty hunter using his ability to command a group of poisonous BUGs with his instrument. His original intention was to use his BUGs to poison and kill Pacifica, but Raquel subdued him in order to collect the antidote from his cave. In awe of Raquel's devotion, Kidaf stopped going after the Scrapped Princess' bounty, and even agreed to help Pacifica find her siblings.

Prince Forsyth/Forsis is the Crown Prince and biological twin brother of Pacifica. Unlike his father, the King, he has his people's welfare as top priority, and despises all unnecessary bloodshed meted to take out the Scrapped Princess. For this reason – the other being his physical resemblance to his mother and Pacifica – he is constantly at conflict with the King. At the end of the series, Forsyth kills Pacifica and himself to stop the prophecy from being fulfilled. He is revived from death when Pacifica 'destroys' Providence.

Princess Seness Giat "Beast" Princess of the Giat Empire, she is quite short-tempered, due to her harsh childhood, where people feared her, and she and Pacifica often argued after they met. She is a warrior princess skilled with her sword and magic, and manages to revive the giant floating fortress Skid used 5000 years ago in the Genesis Wars, with the help of the Dragoon, Natalie.

Fulle/Furet Fulle, eighteen years old, first appears after the spell Ginnungagap creates a destructive tidal wave. Pacifica, who was on a boat, washes up on an island with no memory of who she is. While she is staring at the ocean, Fulle is assessing the damage done to the city. Pacifica follows him home in hopes that she might run into someone who knows who she is. For the next couple of days, Pacifica, now named Pamela by Fulle for the time being, lives with Fulle enjoying what would be an everyday normal life. After some time, both Fulle and Pamela find out that her real name is Pacifica and that she is the Scrapped Princess. Fulle stays behind to keep the soldiers from getting any closer to Pacifica and is killed.
