Sylvester

Jilvester (Sylvester in Eng ver.) is a character that appears in the Ascendance of a Bookworm series. He is the older half-brother of Ferdinand and a senior noble in Ehrenfest. He is also Aub Ehrenfest, the archduke of the terroitory.

History
Due to Ferdinand's harassment by his mother, Jilvester told Ferdinand to join the temple, which would remove him from the family's succession and keep him out of noble politics. Despite this seemingly harsh banishment, the two brothers appear to still be on good terms.

Personality
The opposite of his younger brother, Jilvester often acts impulsively, leading most people to think that he is younger than he actually is. He is a relentless teaser, but he can get serious in a heartbeat when needed.

The Spring Prayer
Jilvester is introduced to Main as a blue robed priest who accompanies her and Ferdinand for the spring prayer. He took a keen interest in Main and those around her, such as her chefs and the orphanage. Despite his child-like behavior, he is shown to take Main's safety seriously when giving her a magical necklace for protection.

Trivia

 * He is shown to be skilled at hunting, having killed 1 deer, 4 birds (one of which was mid-air) and several scavenging animals
 * When Myne finds out Sylvester is the Archduke, she briefly becomes very worried about the future of the duchy.
