Al

Aldebaran (アルデバラン), commonly known as Al (アル), is Priscilla Barielle's knight. Like Subaru he is a normal person that has been summoned.

Appearance
Al wears a black Volakia made helmet along with a green vest, tan pants, sandals, and an orange cloak. He wears the helmet to hide the injuries on his face and also only has one hand due to an incident while he was in Volakia. He carries his sword in a sheath on his back.

Personality
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.

History
Al was summoned to the different world 18 years earlier, and lost his left arm around the same time.
