Crow Armbrust was a Thors Academy sophomore, and a mentor to Rean Schwarzer after the school orientation. As the story progresses, Crow was assigned to class VII to acquire school credits due to his slacker attitude.
As the uniform's representative color, Crow Armbrust comes from the commoners. Despite being a slacker, he remains on friendly terms with his fellow classmates; Student Council President Towa Herschel, Angelica Rogner and Georges Nome. A habitual class ditcher who was in danger of being a repeater, he was temporarily brought in to Class VII as a way to rack up school credits.
While not particularly serious-minded as a person, Rean and the other members nevertheless accepted him as one of their own.
