Noiz, or formally known as Wilhelm, has a rebellious, abrasive, and confident personality, often appearing aloof due to a traumatic childhood marked by isolation and his rare condition, Congenital insensitivity to pain (CIP), but underneath he yearns for connection and kindness, becoming fiercely loyal and protective of those who accept him.  He's a genius hacker, absorbed in his work, and dislikes being touched due to nerve pain, which contrasts with his desire for affection.
