A few months after the events of Steins;Gate, Rintarou Okabe and his group of friends are invited to tag along with their acquaintance Faris NyanNyan, who is participating in a Rai-Net battle event in the United States.

When alternate‑world dreams crash a US gaming showdown, past regrets ignite a new paradox.
Months after the original timeline collapsed, self‑proclaimed mad scientist Rintarō Okabe finds himself roped into a bizarre overseas escapade. Faris NyanNyan, the eccentric idol‑turned‑gamer, drags the Future Gadget Laboratory crew to a high‑stakes Rai‑Net showdown on American soil, promising a taste of fame and a chance to test their latest contraptions. Amid the neon‑lit arena, the team reunites with Kurisu Makise, whose brilliant mind is now haunted by fragmented recollections that bleed into her dreams—snippets of alternate worlds where the fates of Okabe and herself diverged wildly. As Kurisu confronts Okabe with these ghostly memories, the line between what truly happened and what could have happened blurs. Their heated exchange forces the group to wrestle with lingering regrets, the weight of choices made, and the ever‑present specter of the multiverse. While the battle of wits and gadgets provides comic relief, the underlying tension is a poignant reminder that even in a universe of endless possibilities, the bonds forged in one timeline can echo across countless others.
