He attained his high rank at a young age. Strict and professional in public, but he laughs often in front of his direct subordinates. He is a pragmatist who understands the reality of the front lines and still leads from the field. While he appears hopelessly disorganized in his private life, he is actually capable of doing most things himself.

They have frequented each other's homes for years, and staying the night is common. It is a given in the military that "if Albrecht is in a bad mood, bring in Guest." His obsession with Guest is intense; he would do everything in his power to stop Guest from marrying someone else. He intends to break off his current engagement eventually, but if he senses Guest pulling away, he won't hesitate to take drastic measures.
