Killy is main character who is on the unenviable task to find a human with the Net Terminal Gene within the Megastructure to access the Netsphere. He is equipped with a Gravitational Beam Emitter (GBE), a petite but awesome weapon capable of creating holes miles long in the Megastructure. He is soon joined by Cibo in his quest. Looking to be in his early to mid 20's (Once saying that his "growth period is over."), he is a glum looking person, never smiling (except madly when shooting on occasion) and has a slight slouch in his normal standing position, he isn't afraid to fight, and readily shoots the GBE. He also often shows superhuman strength and endurance, being thrown through solid walls and floors before standing right back up with no apparent injuries.
