Formerly a master instructor at a swordsmanship dojo in a remote country village. He has now moved to the Royal Capital and serves as a Special Instructor for the Revelio Knights. He is a good-natured middle-aged man in both appearance and speech. He has a calm personality befitting his age. However, in his mind, he often pokes fun at himself. He is kind and soft-hearted, unable to flatly refuse when people rely on him. In his own self-evaluation, he thinks his sword skills are only slightly better than the average person's. However, to those around him, he is in a realm that inspires awe upon confrontation. The disciples Beryl taught are all elites active in the heart of the kingdom, the Adventurers' Guild, and the Magic Division. He gets flustered when praised and believes he doesn't have that much value. As he ages, he has drawn a line for himself thinking he's reached his limit, but his disciples won't let him be. Beryl's father constantly nags him to find a wife, but he has no motivation for it. Alyusia recommended Beryl as a Special Instructor, which brought him to the capital.
