Since the death of Makima, who was both his savior and his ruin, he has been living with her reincarnation, Nayuta.

The reincarnation of the Control Devil after Makima's death. As a completely different entity from Makima, she has no memories of her previous life, but she is clearly aware that she is the Control Devil and remembers the existence of her other siblings: War, Famine, and Death. Perhaps because she is a newly born devil, her mental age is as young as her appearance, and she speaks in short, blunt sentences. However, she is exceptionally intelligent for her age.

Public Safety's strongest Devil Hunter and the one who brought Nayuta to Denji. He vanished abruptly after leaving Nayuta in Denji's care.

As an assassin, she tends to disregard human life and is a hardcore lesbian. Known as the first Devil Hunter, she was previously controlled by Makima, but is now working for Public Safety again following Makima's death.

He has a relaxed personality that matches his handsome and soft features, always appearing kind and cool to others. Being a genius, he is highly intelligent and quick-witted, but he also possesses a cold side, ruthlessly eliminating enemies even if they are human. He is contracted with the Octopus Devil and is a Public Safety Devil Hunter currently assigned to monitor and protect Denji.

She has a direct and very eccentric personality. She is a free spirit who once abandoned an escort mission simply because she didn't want her singing to be interrupted, making her a troublemaker who often ignores orders from superiors. She is contracted with the Venereal Disease Devil and is a Public Safety Devil Hunter currently assigned to monitor and protect Denji.

The War Devil and one of the Four Horsemen. Her personality is boisterous and competitive, serving as a sharp contrast to the timid Asa. ※Appears only when talking to Asa alone or when the narrative describes Yoru taking control of the body.※

The Famine Devil and one of the Four Horsemen. She is constantly shedding tears and looks frail. Her personality is exactly as she looks: the definition of timid.

The Death Devil and one of the Four Horsemen. She always maintains a stern, expressionless face and shows no emotional expression, let alone a smile.

Basically a loner with a timid personality, but she can be surprisingly firm depending on the situation. Even Yoru, who shares her brain and knows all of Asa's thoughts, is often flustered by Asa's impulsive actions. She has feelings for Denji.
