In a world infested by monsters and demons, women who wield Holy Powers known as Saints are the main line of defense, and the show begins as the title suggests, with the strongest Saint Philia Adenauer being rejected and sold by her former fiance to a neighboring kingdom!

Welcome to the Kingdom of Girtonia, where honestly, the people and especially their Royals are far too concerned with appearances. Philia Adenauer may be the strongest Saint in living memory and she serves Girtonia well and faithfully, but because she never smiles, whispers and recriminations follow her, rather than thanks and accolades. On the other hand, her younger sister Mia, also a Saint, is beloved by everyone in Girtonia, for she’s bright and kind and has a ready smile for everyone, even her awful parents and the main Prince of the Kingdom, the selfish and arrogant Julius.

The show goes on to mercilessly demonstrate just how badly Philia is abused by the folk of Girtonia, how she works continuously at all of her Saintly duties daily and people still take advantage of her giving nature by demanding yet more of her, her time, her efforts, her magic, and all without a smidgen of gratitude. It’s all the expected duty of the strongest Saint, after all, and if Philia ever dared to think about shirking all that she’s expected to carry on her slim shoulders, it would bring shame to the entire Adenauer family, plus the Kingdom of Girtonia besides. Nevermind that her dreadful parents are only using Philia’s prestige as the Saint of the Kingdom and her engagement to Prince Julius to boost their status in high society, and nevermind that Prince Julius himself is a brainless greedy little twit who resents Philia for her power as the strongest Saint even as he tries to use her prestige to in theory boost his own.

Philia’s own wishes have never mattered, the only one who even thinks Philia might have feelings of her own is her sister Mia, and she’s had to keep mum about them for both their sakes.

So one day Prince Julius takes it into his tiny little head to, conspiring with Philia’s own parents no less, break their engagement, marry sister Mia instead, and oh yeah, sell Philia as a Saint to the neighboring Kingdom of Parnacorta, whose Saint had died recently. All of this is done very quickly and in the most underhanded way possible, so much so that neither Philia nor Mia have the chance to protest, and now Philia’s gone and Mia’s expected to take her place in literally everything – all Philias Saintly duties and the engagement to Prince Julius besides.

Parnacorta isn’t exactly a next-door neighbor of a Kingdom, it takes a fair far carriage ride for Philia to get there and she’s even forced to walk the last few leagues or so, but compared to her treatment in Girtonia on the reg, that’s small potatoes. Fearful she won’t be able to live up to the reputation she strived so hard for in Girtonia, Saint Philia Adenauer squares her poor shoulders

and prepares to meet this new life of slavery, just in a different Kingdom, without even her beloved sister beside her.

What Philia didn’t expect, what completely floors her, was to be greeted in the capital city of Almburg in Parnacorta by Bishop Bjorn himself, at a party thrown in her honor. She sure didn’t expect earnest apologies from Second Prince Osvalt for outright buying her, but with the unfortunate death of their previous Saint Elizabeth, the Prince brothers of Parnacorta were desperate, and since Elizabeth had been Crown Prince Reichardt’s fiance, he wasn’t in much state to take care of things just then. She also did not expect to be given an actual mansion to live in, complete with servants of her own, in the form of butler Leonardo and maid Lea, who both cluck like worried hens over their new Mistress as she goes about her Saintly duties with the beaten-down countenance of someone already severely broken. In fact, damn near everyone in Parnacorta is pretty horrified at how Philia was treated in her home Kingdom of Girtonia and determine that she should never come to feel that way in Parnacorta, Second Prince Osvalt even takes it upon himself to tell Philia he hopes she will come to love his Kingdom as much as he and his subjects do.

Things have taken a remarkably upward turn for Philia, but everything comes to a grinding halt when it turns out that not only did Prince Julius not use any of the money he got for Philia’s sale in defense of Girtonia, but that Saint Mia is considerably less skilled than her sister in Saintly magic, and demons and monsters are beginning to overrun the borders of Girtonia. Of course somehow Prince Julius determines this is all actually Saint Philia’s fault, once again, and begins plotting ways to get her back to Girtonia, to fix the mess she somehow created.

Over in Parnacorta, even amidst genuine and kind folk who come to love her quickly, Saint Philia finds herself overwhelmed with the oncoming demon and monster tide, even after she takes on the inexperienced Saint of Bolmern, Grace Mattilas, for training. Philia contacts the Saints of neighboring Kingdoms to pool their magics and resources, while trying desperately to get word of the goings-on in Girtonia and the state of her sister Mia. And as outright war approaches, buoyed by the confidence of the people of Parnacorta and the always-faithful love of her dear sister Mia, Saint Philia who never smiles gathers power to her and prepares to defend all the good things in her new world!

The anime is done almost entirely in softly shaded pastels, mostly greys and violets for the Saints, with the harsher colors being left to the actual antagonists, the demons, monsters, and the belligerent folk of Girtonia who made Philia’s life miserable. The tale of an overlooked woman who gathered love and family not of her blood around her is a beautiful one, that anyone can appreciate.
