Steins;Gate 0

Rintarou Okabe has abandoned his theatrical "mad scientist" identity after a devastating failure and is trying to live as an ordinary college student. His friends know little about the time-travel experiences he is attempting to leave behind, but his past becomes impossible to ignore when he attends a university technology forum.

There he meets Maho Hiyajou and Professor Alexis Leskinen, who unveil Amadeus, an artificial intelligence capable of preserving a person's memories and reproducing their personality. Okabe learns that the system contains a simulation of Kurisu, one of their former university colleagues. Being asked to help study that simulation forces him back toward memories and consequences he has been desperately trying to escape.
