He is a blue priest who serves as the High Priest of the temple of the city of Ehrenfest. He is tall and slender, he has light blue hair that reaches down towards his shoulders and pale golden eyes. People frequently mistake him by being older than he really is. He was the son of a concubine in noble society. Regardless of his father’s true wife, his relationship with his older half-brother was not at all bad. After his father's death, his half-brother recommended him to join the temple. Before he became the High Priest, with the help of his half-brother he built a library inside the temple, one that even nobles with unfortunate economic circumstances would be able to use.

Despite the fact that it had not been terribly long since he joined the temple and that he was still very young, he became the High Priest due to all of the people who were primarily in charge of managing the temple’s affairs had been called away to noble society, leaving him to take on every single aspect of running the temple.
