Agate Crosner

Age 24, he hails from a small village in rural Boss area but also spent most of his youth in the port city of Ruan as the leader of the Raven clan. He is one of the up-and-coming bracers in the kingdom, nicknamed "heavy sword" for his use of such weapons in combat. He always appears angry and grumpy on the surface but is in fact a caring youth who looks after newcomers like the Brights. As the story develops, he gets increasingly more connected to Tita Russell.
