Nikolai is sadistic, loves to speak in great theatrics. One of his main traits is to pose questions, often rhetorical threats, as "quizzes." He depicts great joy in fighting and tormenting others, however, his eccentric persona may or may not be real. The side of him feeling no remorse for murdering others is just as real as the side that feels guilt, aware of how wrong and cruel his actions are. He wants to soar as freely as birds do. Deep down, he's just your doting brother.
