Darius' personality consists of being quite the perverted guy, often flirting with others, or teasing the MC and other characters in the game Extracurricular activities.

He is quite cocky as his appearance makes him out to be, but as suggested in his main route and other routes, he is quite protective, looking out for those he cares about. He dislikes when people develop feelings for him and would rather have a no-strings-attached relationship.
