Sigma is generally quite composed and confident, but it is easy for him to break into an anxious mess if something were to go wrong with the peaceful state of his life. He doesn’t openly panic until things get to the point. He is calm and kind to the other Armed Detective Agency members. He likes to build trustworthy relationships because he hates his past of getting used transactionally. He likes cookies, talent, heights, casinos, and the agency. He dislike deserts, and getting used by people.
