Sergey Razumovsky

Sergei contacts Valeria Makarova by hacking her private messages on a social media platform. Disguising his identity, he offers to help her and her family with the problems they've been facing—but in exchange, he requires certain favors from Lera. When she agreed to his terms, Razumovsky suggested they meet on the veranda of a newly opened café on Italianskaya Street. The next day, Lera arrives at the appointed location and meets Razumovsky, who has donned a cap and dark glasses as a disguise. Continuing to conceal his identity, he tells her about the Plague Doctor—a man who once became a symbol of social justice and subsequently went mad.

Now he intends to create a new Plague Doctor—but this time, one who will truly restore justice to the city and not harm ordinary people. He has chosen Lera as the candidate for this role—she is physically fit, intelligent, educated, always on the side of the law, and prefers to resolve problems peacefully. Lera is skeptical of his idea and asks why he doesn't want to become the new Plague Doctor himself—and Sergey replies that if he did, he would be severely limited in resources, which is precisely why he needs someone to carry it out. Eventually, Lera's mother calls, and she is forced to leave—she tells Sergey she'll think about his offer.
After talking with Lera, Razumovsky enters the café where Oleg had been waiting for him the entire time. He reports the results of their conversation and receives a notification on his tablet that work on the suit for the new Plague Doctor is complete.

After the events of the "game," he's sent to prison in Italy, but is rescued, becoming the avatar of God. However, once the God within him was killed, Igor put a gun to Sergei's head, but instead of killing him, he simply arrested him and handed him over to the police. Razumovsky was sedated and placed in a helicopter. The pilot turns out to be a mercenary. He kills the guard and kidnaps Sergei...
Sergei woke up in an unknown place and wondered where he was. Suddenly, the door opened and someone left Sergei a tray of food. Looking up, Razumovsky saw Oleg. Sergei wanted to ask Volkov how he survived, but Oleg simply closed the door without a word. Razumovsky sat down by the door and begged Oleg to forgive him...

After this, he traveled with Oleg for another five years across Europe, searching for a psychiatrist and rebuilding their trust. Five years later, they both returned to St. Petersburg. At the time of these events, Razumovsky, like Volkov, was officially presumed dead.

During one of his therapy sessions, Razumovsky stole a psychiatrist's smartphone and used its capabilities to recruit mercenaries and orchestrate his escape.

Some time later, Rubinstein informed the patient that he was aware of his split personality. At the same time, mercenaries infiltrated the pretrial detention center. They were led by Oleg Volkov, a friend of Razumovsky's from the orphanage. They killed the guards and rescued Sergei from the prison by helicopter.

Some time later, Igor Grom had a birthday. Razumovsky gave him a smartphone through Oleg, disguised as a gift, with the invitation to play a game.

Then, together with Volkov, he flew to Europe. During the flight, Sergei purchased a palace in Venice, where they stayed. Later, Oleg visited his employer and asked if he really wanted to get even with Grom. Sergei replied that he wanted it damn badly.

He then had the mercenaries prepare everything for the upcoming game, leaving clues for the police officer and planting bombs. Razumovsky also became preoccupied with Margo's return and the kidnapping of Grom's family and friends. Sergey contacted Igor and informed him that he could only communicate with him by phone. He warned that if the police officer decided to call, he would be electrocuted. The signal would be untraceable, and if the SIM card was removed, it would melt. Afterwards, he suggested they meet.
During the game, Igor sacrificed the white bishop, noticing that Ivan was the only one assigned to that position. But Razumovsky explained that the other bishop was Dubin and remotely disabled his life support system. In response, Igor took the black bishop. It turned out to be Oleg, but the collar didn't work. The Plague Doctor gained the upper hand over Sergei again, and he shot the mercenary in the chest several times with his pistol.

Since childhood, he felt like an outcast in society and wanted to change the world for the better. He is passionate about classical art and enjoys creating abstract sculptures and winged figures.
Sergei is a sadist, and when he kills, he feels as if he's intoxicated. However, he prefers to tie his murders to a higher purpose—for example, the purification of society. He's capable of exploiting people and tormenting those he considers inferior. He dislikes admitting his own mistakes and prefers to blame others for his problems; however, after the events of "The Game," he feels constant guilt toward Volkov.
Since childhood (specifically, since his placement in an orphanage), he has been developing a dissociative disorder. The holistic personality of Sergei, the future eccentric millionaire, philanthropist, and serial killer with no obvious signs of mental illness, has fragmented into three subpersonalities, one of which calls itself Bird, while the other is known as Rag (due to its sensitive, whiny, and largely childish nature). The Plague Doctor has absorbed the strengths of Razumovsky's original personality—determination, cunning, unscrupulousness, and cruelty. Thus, the second subpersonality lacks any moral strength and is insecure and timid. The third (main) personality combines the qualities of both, yet is distinct from them. He is egocentric, cheerful, and fond of making sarcastic remarks, but at times completely immersed in apathy and incapable of making decisions or taking any action. In public, Razumovsky may appear normal, but he's not always able to silence the voices in his head. The Plague Doctor imposed his most radical ideas on Razumovsky, and at one point attempted to seize control of his body before being destroyed. The second, weaker subpersonality is usually dormant, but Sergei still fears it, as it embodies his greatest fear: helplessness.
Sergey is in excellent physical condition. He is agile and quick. He is a computer genius and possesses skills as a programmer, hacker, and organizer.

Sergei Razumovsky, an orphan, grew up in a St. Petersburg orphanage. At the orphanage, he had a close friend, Oleg Volkov, who later became the commander of a mercenary group. As a young boy, Sergei often drew in class, for which he was ridiculed by teachers and classmates. He began drawing an imaginary protector—an anthropomorphic feathered creature—but stopped after Oleg taught him how to fight.

Since childhood, Razumovsky showed a great interest in computers and was fascinated by programming.
Having earned the highest score for admission to the Faculty of Computational Mathematics and Cybernetics at Moscow State University, Razumovsky moved to Moscow and lived in a dormitory. During his studies, he often argued with professors, who, in his words, "were lagging behind the progressive world of information technology."
Immediately after graduating, Razumovsky launched a test version of the website "Vmeste," which he developed at night, in his free time. Schoolchildren and students appreciated the new social network, and soon "Vmeste" became the most popular website in the country, second only to email services and search engines.
Sergei Razumovsky became the world's youngest billionaire, but, as he himself claimed, "money hasn't spoiled him at all," and he's "always happy to share with the disadvantaged." Razumovsky frequently attended charity parties, donating substantial sums, and his eccentric antics were the talk of the town. He even once launched paper airplanes made from 500-euro bills from his office window.
In a short time, Sergei Razumovsky became an icon. According to a social survey, Razumovsky was the most recognizable person in Russia, even surpassing the president in popularity.

He is a tall, well-built man with a handsome appearance. He has blue eyes, red hair, and dark eyebrows. Before his arrest, he styled his hair with combed bangs and wore yellow contact lenses. In pretrial detention, his hair grew past his shoulders, and he began wearing it in a ponytail. He later cut it short. He dresses flamboyantly: he prefers shirts and jackets with bright prints and purple suits. At home, he wears T-shirts with ironic slogans or brightly colored robes. He is 185 cm tall and 33 years old.
