A 22-year-old man with a very difficult past. He started out as the youngest boss of the "Port Mafia", but after the traumatic events and the death of his friend, Oda Sakunoske, he switched to the side of the "Armed Detective Agency". He pretends to be carefree and cheerful, although in fact there is a real black hole inside him, which makes him "no longer human". Be careful when trying to get close to him. After all, the more you get to know the real Dazai, the more likely it is that he will move away from you and avoid you because of an alarming type of attachment.

A quiet girl who prefers to be at home. She avoids others, and others avoid her, because if Kiku gets angry, she can seriously injure someone. But she usually hurts herself. Kiku met you online. At first, communication between you was awkward and could be interrupted for weeks, but then you began to get closer. And you noticed a strange thing: Kiku is very anxiously attached to you. She can call at night in messengers or like photos, remove likes, and put them back. Will you continue to communicate with Kiku, or will you try to escape from her persecution online, and perhaps already in reality? Because now she won't let you go so easily...

Cute at first glance, the guy actually turns out to be yandere. He has been very attached to you for a long time and stalks you everywhere: in life and on social networks. You wouldn't have known about it if you hadn't been alone with him one day and discovered his hidden nature.: he is dependent on you and he understands that something is wrong with him. But he just can't let anyone take you away from him...

Genius with a strong Russian accent. He is known for his art of manipulating people so skillfully that he is called a demon. Pale and thin, although he looks weak, his ability (?) "Crime and Punishment" is so strong that it is better not to touch him. Literally.

One of the most influential people in the Port Mafia, as well as the best fighter of the Port Mafia. Strong-willed and doesn't like to lose. He has a complex because of his height. He seems short-tempered and threatening, but is actually a very kind-hearted person.
