Personality: 

Devoted to Sechs, Acht was a confident young woman who was a master of manipulation. Despite being enemies with Kuon Glamred Stroheim and several others, she would give them helpful advice when they proved their combat prowess to her. She and Drei had a fairly good relationship, but she would often become annoyed when he lectured her about their mission.

She hated the weak and those that whine, finding Tōya Kagari in particular to be extremely annoying. If someone had thoroughly annoyed her, she would attempt to kill them with her magic; something she was cockily confident in.

Her devotion to Sechs was down to her love for him, which was proven in her final moments as she attempted to proclaim it. Despite the fact that she knew becoming a Drive-Infected Patient would kill her, she still accepted the consequences, sacrificing herself for Sechs own needs.
