Within a claustrophobic, tech-drenched megastructure that encompasses the entire planet, Killy, a traveler with a small but super powerful gun, silently traverses countless levels of what is called “The City.” He’s searching for “net terminal genes” which may allow him to connect with The City’s neural center and stop its growth. Along the way he meets various transhuman inhabitants, but is also pursued by The City’s cyborg defenses. A prequel, NOiSE, was released in 2001, and a sequel, NSE: Net Sphere Engineer, began in 2004. A 6-part original video animation based on the comic was released in 2003.
