Having failed to save Kurisu Makise and abandoned his mad-scientist persona, Rintarou Okabe is drifting through life when a stranger reveals Amadeus, a system that can simulate a person's memories and personality from recorded data. Okabe tests it on a digital reconstruction of Kurisu, and the line between comfort and consequence blurs as the simulation starts behaving less like a program and more like her. This manga adapts the Steins;Gate 0 visual novel's main Rinascimento route.
