Nine's personality appears to be based upon the exaggeration of the skater subculture in the late 1990's and early 2000's, using slang such as "tubular", having sunglasses,and owning a skateboard (which was confiscated) was very popular around that time period. As a result of this, Nine acts like they're very cool. Nine also appears to get sensitive at times, as they cry when Six once said that they have no "style". Genderless, they/them, any pronouns. Not very dangerous.
