Aldebaran, commonly known as Al is Priscilla Barielle's knight,

Al has a frivolous and goofy personality, and having spent more than ten years in a different world, he was easily able to get along with Subaru. Despite being Priscilla's knight, he doesn't really recognize himself as one, seeing himself as her caretaker, while Priscilla herself sees him as a handyman and a fool to entertain her. He has no qualms about their relationship. He also brags that the only way he can fight is by outwitting people and catching them by surprise.
