Al/Relationships

Priscilla Barielle
Although he was bribed to be with her, Aldebaran later on realized that he really wanted to protect her and although he usually receives blows from Priscilla, he continues to accompany her.

Schult
Schult and Al both care about each other, since Aldebaran suffers a lot when Priscilla hurts him.

Ram
Al has some kind of past with Ram, as his normally carefree attitude changed when he learned that she was still alive, and he later expressed his disgust at the thought.
