Episode 9 deals with complex character interactions and the revelation of hidden truths.

The episode begins with a tense confrontation between Ange and Byaku, a character from an earlier episode. Ange, who still harbors resentment toward Byaku for his actions in Bordeaux, is on the verge of attacking him. However, she relents when she recognizes Byaku's remorse and his willingness to make amends.

The plot then shifts to the inquisition of the Holy Court of Lucrezia, an underground order that deals with heretics. The inquisition is after Byaku because his father is entangled in a power struggle at the court. Angel's interactions with Byaku and his companion Char reveal her complex emotions and her sense of justice.

The episode also focuses on Lady Marguerite, an elven princess introduced in the previous episode. Marguerite's interactions with her great-uncle, Lord Graham, and Belgrieve reveal her desire for personal recognition and her struggle with her elven heritage. These conversations provide insight into her character and her relationship with her mentor.

The episode also addresses the theme of atonement, as Byaku and Char express their desire to make amends for their past actions.

A key moment is the discovery of a mysterious child who emits the mana of a Demon King. The child's presence raises questions about the nature of the Demon Kings and the power dynamics in the story's world. Belgrieve's decision to raise the child despite its potential danger demonstrates compassion and a willingness to challenge norms.
