Al is Priscilla's knight. Initially introduced as Priscilla's constantly abused "knight", it is soon revealed that there might be more to him, following the revelation that, like Subaru, he was summoned to this world from Japan roughly 18 years ago. Although very skilled at fighting due to the time spent in Vollachia, Aldebaran does not like to make enemies, as he considers that taking care of them when a problem occurs requires a lot of work, but Priscilla doesn't seem to care about this.
