Personality: Kind and calm.

Name: Nakiso Gender: Male Music: He creates songs with an unstable and eerie atmosphere. He frequently uses scratching sounds typically found in horror movies, and his lyrics tend to use relatively simple and direct vocabulary repetitively to create a paranoid atmosphere.
