History
Sylvester is the son of the previous Aub Ehrenfest amd Veronica. He was raised to succeed Aub Ehrenfest, due to his large amount of mana. He has to older sisters, Konstanze and Georgine. Before Sylvester was born, Georgine was raised to become Aub Ehrenfest.

Ferdinand and Sylvester first met after Ferdinand's baptism. They have the same father but different mothers. Sylvester is six years older than Ferdinand and looked and cared for his younger half-brother.

Due to Ferdinand's harassment by Sylvester's mother, Sylvester told Ferdinand to join the temple to escape Veronica's harassment, which would remove him from the family's succession and keep him away from noble politics.

Personality
The opposite of his younger brother, Sylvester 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. He is described to have a good heart deep down, although he acts like a spoiled child.

The Spring Prayer
Sylvester is introduced to Myne as a blue robed priest who accompanies her and Ferdinand for the spring prayer. He took a keen interest in Myne and her surroundings and requests a tour through the orphanage and the Myne workshop. There he met Benno and talked with him in secret. He also demands a visit to the lower city's forest to hunt. He joined Lutz and Leon who are responsible to take him and the orphans to the forest. Dressed in the clothes Myne got for him, he departs with a bow in hand with the group. During the time in the forest he interacts actively with the orphans and asked them about Myne.

Despite his child-like behavior, he is shown to take Myne's safety seriously when giving her a magical necklace for protection after parting their ways at the end of the forest trip.

During the Archduke Conference
While Sylvester is away with Karstedt due to his responsibility as Aub Ehrenfest, Count Bindewald entered Ehrenfest with a forged permission from the High Bishop. A fight occured in front of the High Priest's room. After Ferdinand stepped in and the fight almost ended, Sylvester made his appearance with Karstedt.
