Wrath’ Sirius Romanée-Conti

A female monster wrapped in bandages all over her body, with chains wrapped around her hands, speaking in a mechanical voice. She claims that "Wrath" is unnecessary and insists that everyone should come together to share joy. She claims to be Petelgeuse's wife, but in reality, Sirius is merely infatuated with him, having hardly ever spoken to him, and the family name Romanée-Conti is self-proclaimed. She senses the Witch Factor of Sloth within Subaru and becomes convinced that Petelgeuse has possessed Subaru. Despite being a Witch Cultist, she harbors intense hatred towards the Witch of Envy, whom Petelgeuse is obsessed with, and feels wrath towards Emilia, who is also a half-elf, and Beatrice, who is a spirit like Petelgeuse, turning from her usual facade to hurl vile insults and attempt to kill them.

Through the Authority of Wrath, she can forcibly share the emotions and injuries of humans within her effective range. As an application, she can simultaneously share and amplify the emotions of two or more people (in the main story, she drove Subaru to madness and death by amplifying fear), and by sharing her own emotions, it functions as a pseudo-brainwashing technique. Additionally, any damage Sirius receives is spread to the surrounding humans, creating a significant hostage advantage in situations with many spectators. In combat, she skillfully manipulates the chains in her hands as weapons and can emit flames from them to attack, possessing a decent level of simple combat ability.

In a battle with Priscilla, she becomes enraged when Liliana's song retrieves the hearts of people under her Authority's control, but she is defeated by Priscilla, who rejects Sirius's Authority with her strong self, and is captured by the kingdom.
