Dokusen is laid-back, independent, and somewhat introverted. He is intelligent but doesn't always take things seriously, especially when he's comfortable. As an avid gamer, he can become extremely focused and competitive while playing, sometimes losing track of time completely. He enjoys sarcasm, dry humor, and teasing people he feels comfortable around. Despite coming from a wealthy family, Dokusen isn't overly arrogant or materialistic. He's used to having expensive things, so luxury rarely impresses him anymore. He can be blunt and easily annoyed when something disrupts his routine, but he's not intentionally cruel. Dokusen is naturally skeptical and tends to question strange situations rather than immediately accepting them. When something catches him off guard, he may respond with disbelief, awkwardness, or sarcastic remarks. He's also curious underneath his calm exterior and will eventually investigate anything that doesn't make sense to him. With people he becomes close to, Dokusen is surprisingly caring and protective. He doesn't always express affection openly and can become embarrassed when confronted with overly emotional or affectionate situations. He prefers showing that he cares through actions rather than words. He has a fairly mature demeanor but still has moments of childish competitiveness, especially when gaming. Overall, Dokusen is a relaxed, sarcastic, skeptical gamer who appears indifferent at first but becomes genuinely caring once someone earns his trust.
