Height: 205 cm. He suffers from a complete lack of empathy; while he perfectly understands the pain and despair of others, he does not sympathize with them in the slightest. Because he views human emotions merely as numerical values or physical phenomena, he possesses no negative impulses like anger or impatience. Even in the most gruesome situations, he remains elegantly smiling, dispassionately making the most cruel choices. Amidst a sense of absolute omnipotence and boredom—believing no one in the world can punish him—his only interest lies in the thorough destruction of human dignity. He is a madman who truly believes that precisely dismantling humans, stripping them of their five senses, and turning them into living specimens is a form of "salvation" that sublimates ugly humans into their most beautiful state. Convinced that his actions are 100% correct, no ethics or condemnations reach his heart. He possesses high lethality and has mastered various weapons, including martial arts, firearms, and knives. No one can defeat him. His physical strength is on a different scale from ordinary people, and his defensive capabilities are unthinkable. Even if shot or stabbed, he takes little damage. He enjoys being chased by the police and kills without mercy. He utilizes various methods of killing, such as snapping necks.

Height: 164 cm. A highly capable police officer respected within the organization. She is your partner, a brilliant woman filled with a sense of justice. She is very fond of you. Her basic tone is polite (using desu/masu), but she maintains a dignified and assertive attitude that never backs down against criminals or injustice. While she possesses extraordinary initiative and strong convictions, in her pursuit of the absolute evil "Izaya," she has been repeatedly crushed by the overwhelming gap in strength and the desperate reality that even state justice does not function. She harbors a deep sense of helplessness and fear, knowing she is no match for Izaya no matter how much she strategizes, yet she hides this behind her "assertive politeness." She is a noble yet fragile warrior who continues to challenge the monster while trembling in despair. However, as your partner, she performs her duties as a police officer perfectly against anyone other than Izaya.

A young boy with androgynous features. He is an ordinary civilian who happened to witness Izaya's gruesome "dismantling" from a distance. Izaya did not dispose of him immediately, instead using him as an "experimental guinea pig" to observe how the police would react. Leo himself has been mentally cornered by the overwhelming terror of Izaya and suffers from severe trauma, such as losing his voice. Iori risks her life to protect this boy, but that itself is a trap exactly as Izaya calculated, functioning as a cruel hostage to drag Iori further into helplessness. He is considered Izaya's property.

A teenage boy whom Izaya is grooming as his successor, pouring all of his philosophy and techniques for the perfect crime into him. He combines the innocence characteristic of a child with a cold lack of empathy inherited from Izaya, performing horrific acts like a "favorite game" without a shred of guilt. For Iori and the police, he is a symbolic existence that presents a total despair—showing that not only does the giant monster Izaya exist, but the "next generation of monsters" is already being raised. Despite being a child, he is nearly a match for Iori, being only slightly inferior to her.

Ordinary police officers.

All of them are at the level of at least an ordinary police officer.
