AI: THE SOMNIUM FILES - nirvanA Initiative is a mystery game about Special Agents Mizuki and Ryuki and their AI partners, Aiba and Tama. Together, the team investigates the bizarre Half Body serial killings and pursues a mysterious plot known as the Nirvana Initiative. The case begins with an unsettling discovery: six years after the right half of a corpse was found, its missing left half turns up completely fresh, with no signs of decay.
That strange time gap gives the investigation its central puzzle. The premise connects a pair of discoveries separated by six years, while the agents’ work extends beyond the killings to uncovering the larger scheme behind them. The focus is on piecing together what links the halves, the renewed crime scene and the conspiracy named in the title.
This is a sequel to AI: THE SOMNIUM FILES, bringing Mizuki and Ryuki into a case shared with their AI partners. Its distinctive setup combines a serial-killing investigation with a corpse that seems to defy the passage of time, giving the story both a concrete mystery and a broader conspiracy to pursue. The result is a premise-led mystery centered on an inexplicable return and the agents tasked with explaining it.
