Yvoire is the Archbishop of Leanbox behind the Parliament Revolt and committed crimes, such as attempting to use IF to betray Neptune by poisoning her. In the end he did it himself and was eventually manipulated by the Evangelist/Conversation.
Yvoire dresses like the other Basilicom archibishops, with a tall Pope-like hat and carrying a book in his hand.
Yvorie was trying to prove that his actions were for the best interest of Green Heart and Leanbox. It was later revealed that he was instead operating covertly.
- A common silhouette is used for other Archbishops in the other Basilicoms.
