Fyodor Dostoevsky

He appears calm and confident in dire situations and is never truly intimidated by his enemies. Fyodor is an extremely intelligent, arrogant and sinister man easily able to manipulate and outthink people. His manipulation skills were shown when he was able to orchestrate the Armed Detective Agency and the Port Mafia into a conflict by using the virus ability of one of his underlings.

Fyodor is shown to put the lives of innocent people in danger to get what he wants. During the cannibalism incident, he was heartless enough to psychologically manipulate a little girl into blowing herself up to "save her brother" when in reality, he convinced her to do it just to crush Kunikida's spirit. While the Agency and the Mafia were hunting Fyodor down, he used a random man in a hood with grenades in his mouth as a distraction.

Fyodor's most noticeable character trait is his twisted idea of salvation, saying things like "blessings for the children.", "happiness to the world.", and "God wants perfection and harmony." all the while committing cruel and unforgivable acts of evil. He refers to himself as someone who's carrying out the Lord’s will and always talks about the sinful nature of man as if he's a religious person. Ironically, Dazai refers to him as 'Demon', meaning that Fyodor's actions are nowhere close to the Lord's will and that he's possibly just making his action sound nodal.

When it comes to his lackies from the Rats in the House of the Dead and his allies from the Decay of the Angel, Fyodor views them as paws he can use to help him achieve his goals and cast them aside later on. He neglected Nathanial Hawthorne's wish to save Margaret Mitchell by brainwashed him and erasing his memories of everything other than her, using his desire to save her for his own benefits. When Sigma finished playing his roll at the Sky Casino, he betrayed him out of nowhere by having brainwashed Nathanial attempt to assassinate him. Dazai even stated that Fyodor would have killed Sigma if he hadn't chosen him to be his helper during the prison break.

All though he's known for manipulating and using people, the only person he possibly saw as a friend was Nikolai Gogol, who often referred to him as "Dostoy". Fyodor never denied being his "bestie" nor does he ever get annoyed by his eccentric behavior. He also praised Nikolai for struggling to lose himself and his emotions. Despite this, when Nikolai attempted to kill Fyodor to prove he can be free from his own emotions, Fyodor threatened the former by saying that he would kill him for trying to murder him.

Shortly after, Fyodor makes it out of the prison and is greeted by Nikolai. Before handing over the antidote for the drug, Nikolai asks Fyodor how he was able to make contact with the outside world, and Fyodor states that he had Meursault's security forces turned into vampires. Before he gets into the helicopter, Fyodor takes a moment to realize that Dazai is one of the two people to have cause him harm. Due to the injurie on his hand, he orders one of his vampire accomplices to piolet the helicopter. However, Due to Bram Stoker regaining control over his ability again, Fyodor gets stabbed in the abdomen by the vampire infected pilot while sitting and letting his guard down, only then to see that Dazai is still alive as the latter emerges from the building. Dazai then tells Fyodor that his weakness was not trusting the people he can't manipulate and that he lacked allies, he then explained that Chuuya was never a vampire as the latter takes out his red contacts and the only reason he survived twice was because Chuuya used his gravity manipulation to slow down the elevator when it was falling, and he used it to stop the bullet, before it went through his skull. Dazai then walks away after taking the case containing the antidote as he lets the infected Pilot driving Fyodor who was unable to reach for the joystick due to his wounds, which led the vehicle to then impact towards a signal tower and crashing onto the ground behind Dazai and the others as Fyodor remarks his disbelief before his life flashes as the Helicopter ignites a powerful explosion, finally Killing Fyodor once and for all. He is known for his pale skin complex with dark violet eyes and shoulder length obsidian hair.
