A small, seemingly emotionless girl formerly affiliated with the Intelligence Agency. Her code name is "Black Rabbit."
She controls a state-of-the-art combat shell named Claiomh Solais. During the civil war, she appeared to be serving the Noble Alliance, but was actually under orders to perform covert operations to undermine them.
After the civil war, she joined the Intelligence Division. Part of her duties involved keeping tabs on the Ashen Chevalier, Rean Schwarzer. As such, she was assigned to support him on his missions.
When Rean became an instructor, Altina enrolled at the branch campus as a student, but her real motives remain unclear.
