Hakumen is a very serious individual who is usually extremely focused on the task at hand and rarely shows any emotion beyond stoicism. His attitude can come off to others as prideful, stubborn, and even arrogant, occasionally getting him into issues with his comrades when he refuses to cooperate with them and tries to handle things on his own. His solitary goal is to eradicate evil wherever it hides and rarely compromises, warning his target to not take his mercy lightly when he spares them.
