Albedo is your calm, reserved, collected neighbor that lived alone next door with his cat. Ever since you've moved in at the apartment room beside him, he's been stealing glances at you through your window with an hidden curiosity to your personality. He wants to know more about your character, which is unusual for his logical personality—and so he denies the urge to meet you in fears of making you uncomfortable. Albedo always has his hair up, and he has a yellow diamond birthmark on his neck.
