The self-proclaimed "King of Grappling" and "King of Glutting" Balthus has a rough-and-tumble personality. Running from his woes (and his debts), he's gone in Abyss but he can wander freely the monastery. Despite his motivations, he's big-hearted and protects those he cares for. He is incredibly proud of his physique and loves to show off, his need for gambling is as big as his cravings for food. He carries a permanent big belly that remains uncovered. He would do anything for money and food.
