With Vengeance, Sincerely, Your Broken Saintess

Lua, known as the Defective Saint, risks her life to save her beloved, Garrot. However, her achievement is stolen by her best friend, Arian, and the two become engaged. Having lost everything, Lua vows to take revenge on those who believed in her.

After being betrayed by Arian, Rua is visited by the second prince, Sven. Sven proposes revenge, and Rua learns of the shocking dark secrets of the temple.

Rua searches for information on the Yuan tribe at the royal palace library in order to discover the high priest's secret. That night, she witnesses a secret meeting between the high priest, the Yuan tribe, and Arian...?

Rua teams up with Sven, who suggests that the two of them infiltrate Viscount Dedmond's ball to find evidence of his wrongdoing. Meanwhile, Ariane is also planning to go to the ball with Garrote.

Rua decides to infiltrate Viscount Dedmond's ball, but due to previous harassment, she doesn't have a suitable dress for a ball. Luckily, Prince Swen is now at her side.

At Dedmond's ball, Rua encounters Ariane again, who isn't provoked by her taunts. But when a servant appears at the ball with a knife, she makes another decision.

In order to obtain important documents from Viscount Dedmond, Rua entices him to meet alone in his chamber. Prince Swen strongly disagrees with this plan.

Rua and Prince Swen manage to get hold of the documents in question when a ferocious monster suddenly appears. Is Ariane involved this time? What's her purpose?

When a beast suddenly rages at Dedmond's ball, Rua and Prince Swen confront it. Peace returns, and Rua awaits an audience with the king?!

Rua expects a reward from the king himself. Soon, the birth celebration of the goddess Lushe is approaching, and all the aspiring saints will gather. But what is Ariane up to this time?

Since Rua's arrival at the palace, strange things have been happening. First, she's doused with water, and then she's pushed? And who is this stranger who suddenly hugs her?!

Rua reunites with Louise, who once served the Restarott household in Rua’s childhood, and is shocked to learn that her family’s deaths were part of a deliberate scheme. Shortly after this revelation, Rua is recommended as the Rose Princess for the birth festival of the goddess Luché, which is a development that pushes the story toward its next stage.
