Agate is a muscular young man with violet eyes & crimson hair from a small village in the rural Bose area called Ravennue. He spent most of his youth in the port city of Ruan as the leader of the local delinquent gang, The Raven Gang, until a certain bracer bested him in combat, thus correcting the path his life might have taken. He is one of the notable bracers in the Bracer Guilds of Liberl Kingdom & the Erebonian Empire, nicknamed Heavy Blade, after his weapon of choice, a bulky greatsword.
