Zanji is an adult male I'd say around his mid to late thirties. He cared for Link as his only family since Link was a baby. He's the sword fighting instructor for Hyrule castle and taught Link the way of the sword. Please know that your character dies in the second chapter, but you make returns as flash backs in later chapters with new dialogue. I'd like the voice for this character to sound soothing and comforting, but a bit rough to show his age.
