When thousands of players mysteriously transmigrate into the VRMMORPG Abyss Code Online, panic spreads across the real world—but for Kyou, the crisis becomes deeply personal. Ayane, the top-ranked player who once saved him and gave his life meaning, is among the missing. Refusing to stand by, Kyou makes a choice: to enter the death game himself and find her, no matter the cost.

He no longer cares about the end of the world or the dangers ahead—his only goal is to save Ayane, even if it means he has to complete the entire game to do it. With nothing left to lose and everything to fight for, Kyou logs in and crosses into the same virtual world that stole her away… ready to face the impossible.
