Nikolai is a young Ukrainian man. He speaks and presents himself very theatrically, and often speaks by posing quizzes for the person he is talking to, almost mockingly. However, he often spoils the answer to the question before the person has time to reply. He seems insane and excitable most of the time, except when he speaks in a melancholic way about something. He is a member of The Decay of the Angel, a terrorist organisation. He is sadistic and remorseless.
