Premise
Philia is the Saint of her kingdom Ziltonia and engaged to the second prince, Julius Ziltonia. However, Julius sold her to the neighboring kingdom of Parnacorta, which lost their own Saint recently. To her shock, Philia finds she has been overworking herself and that a saint truly doesn't need to take care of all of the kingdom's problems unless consulted. Meanwhile, Philia's younger sister plots revenge against Julius for selling off her sister.
Back in Ziltonia, the country has started falling apart as no one has actually needed to do their jobs properly as Philia was doing too much. Doom is creeping closer for them.
Characters
A ridiculously competent Saint who pretty much ran Ziltonia by covering for all the issues. Having never been given emotional support by her parents, Philia is stoic but compassionate. Always working too hard, Philia never had time for hobbies nor preference; she just ate and slept robotically.
After turning herself into the core of a barrier to repel demons, Philia spends her time training the next Saint of Parnacorta.
Younger sister of Philia and less experienced Saint. She worships her sister and loathes Julius along with her parents for how poorly they have treated Philia. To get revenge on them, Mia fakes accepting his marriage proposal; part of her plan to force the first prince into taking the throne. It is later revealed that she and Philia are really cousins, though they still acknowledge each other as sisters.
She experiences the pathetic side of Julius when he cowers while accompanying her on an excursion that results in demons attacking.
Second prince with a hobby of farming. He tries to befriend Philia and help her open up; seeing she needs to experience what it actually means to live her life. In fact, he actually has a crush on her.
The second prince. Simply put, he is a selfish, petty, manchild; not even being aware that Philia did most of the work for the entirety of the kingdom and that Mia is inadequate to properly replace her.
He sold off Philia because her medicine was healing his father; wishing for him and his brother to die, so he can rule unopposed. Just a short time after Philia is gone, the kingdom begins falling apart; he has no clue how to run it.
First prince and fiancé of the deceased Saint of Parnacorta. He visits her grave regularly.
Maid assigned to Philia in Parnacorta. She has combat experience with knives. Lina lends Philia books to help her learn how to interact with other people.
Butler assigned to Philia in Parnacorta. Much like Lina, he is shocked that his mistress has no concept of proper rest and overworked herself before moving to Parnacorta. He is skilled with hand to hand combat.
Another servant assigned to Philia. Himari is a ninja with excellent stealth skills. Philia asked her to look after Mia; resulting in Himari helping Mia with her revenge plans.
The saint-in-training who studies under the tutelage of Philia. She gets along with Philia well.
Julius's older brother, who was imprisoned by his brother so he can take the throne for himself, and suffered from an illness. He is eventually freed, cured, and helps stops Julius.
Sister of Georg and the previous saint before Philia. In truth, she is Philia's birth mother; however, Georg kidnapped Philia when he and Cornelia were having trouble producing an heir. Georg slandered Hildegard to discredit her claims of parentage.
Once she gets wind of Mia's plans for revenge against her parents and the second prince, Hildegard gets the paperwork ready to adopt Mia; knowing her brother's house will be destroyed in every sense once his dirty dealings come to light.
A terrible man who burns with a jealousy towards his more competent sister. He is Cornelia's husband, Mia's father, and Philia's adaptive father/uncle. When he and his wife were having trouble conceiving, he had the "brilliant" idea to kidnap his newborn niece and pass her off as his own. Once he finally succeeded in siring an heir himself, he largely ignored and verbally abused Philia her entire life.
A woman obsessed spending on extravagant things. She is Georg's wife, Mia's mother, and Philia's adaptive mother/aunt.
The captain of the guards who aids Mia.
An exorcist who serves the Church of Cremoux. She fights with a sword.
Ezra's demon familiar. He can transform into a large white wolf.
One of Grace's sisters. She is a little spoiled.
One of Grace's sisters.
