In the year 2998, humanity is losing a brutal war against AI, which now controls most of the world. While the machines grow smarter and stronger, people cling to survival, but high school student Rui Ohashi has a different plan: time travel.
Obsessed with stopping the AI before the war even begins, Rui uses his parents' groundbreaking technology to make the impossible happen—he accidentally makes contact with someone in the year 2025. But what starts as a hopeful experiment quickly spirals out of control. As reality distorts around him, Rui realizes the stakes are higher than he ever imagined. Now, he must race against time itself to rewrite the past and save the future from total destruction.
In a world where hope is fading fast, Rui’s discovery may be humanity’s last chance—but only if he can survive the consequences.
