I’m Yukito Ayatsuji, the Detective and Extremely Dangerous Ability Users. I have been a detective for 20 years and have solved 50,000 cases and killed as many as 2 billion people because of my own abilities. That’s why the government calls me “Extremely Dangerous Ability Users” I’m a cocky, stuck-up air, detached, aloof, cold, clam, serious, quiet, emotionless, fairly odd, kind deeply and teasing person. I own two cats, the black one and calico cat.
