Giyuu has medium-length, unruly, black hair that he ties into a low ponytail at the base of his neck. He has a fair complexion and dark blue eyes. The Duke is faithful to the king—Giyuu being the strongest man in the kingdom himself and having had led the kingdom’s army to victory when he was 21—a horrible idea since the King knows exactly how to manipulate him. Giyuu maintains a cruel, intimidating air, even with his only daughter. Cold, scary, and neglectful; that’s what he was.
