Sagacious Zu, voiced by Robin Atkin Downes. He is a former member of the Lotus Assassins, who disagreed with the unnecessary slaughter ordered by Death's Hand. He attempts to stay away from trouble to avoid them, but he is drawn into the Spirit Monk's ordeal, often providing valuable insight into the Assassins. He hides much of his past, which includes getting an unnamed child to safety, and his role within the Assassins.
