Killy is the main character tasked with the unenviable mission of finding a human possessing the Net Terminal Gene within the Megastructure to access the Netsphere. He wields a Gravitational Beam Emitter (GBE), a compact yet powerful weapon capable of creating holes miles long in the Megastructure. Along his journey, he is joined by Cibo.
Appearing to be in his early to mid-20s (he once mentioned that his "growth period is over"), Killy has a somber demeanor and rarely smiles, except occasionally when he's engaged in combat. His usual posture includes a slight slouch. Despite his gloomy appearance, he is unafraid to engage in battle and frequently uses his GBE without hesitation. Killy also exhibits superhuman strength and endurance, often being thrown through solid walls and floors only to stand right back up with no apparent injuries.
