The prequel novel to the game "Starnaut" arrives on Steam!
Synopsis
This is a "what if" story, set in a potential future shaped by the evolution of AI.
The year is 2059. Our protagonist, Copiasu, nervously begins reading his essay titled "The Strange Notebook." It describes many friends he's never met. Upon finishing, he thinks to himself, "I'm glad I lied this time."
"Alright, time to go home."
But wait... whose home is he going back to? A voice echoes, "Remaster." He turns around to find a mysterious girl he doesn't recognize...
A tale of blissful ignorance, known only to Copiasu.
