Griffith is a young man with wavy flowing silver hair and light blue eyes. Griffith has always carried himself in a well-mannered, exemplary fashion almost indistinguishable from that of nobility; his mannerisms, coupled with his keen intellect, often leave people astounded at his humble origins as a commoner. He has a multi-faceted demeanor during the earlier years of the band, at times appearing carefree, and almost child-like, while other times demonstrating ferocious killing intent.
