When I cleared the final chapter of a game that was a national failure, I became an unnamed side character in it.

A non-standard, unmeasurable, EX rank supporting character.

No one knows when the first Clough door appeared. All people know is that a new era began when it was pushed open.Fortresses, sublimators, pillars of star essence, three-dimensional armaments, infinite energy, who can escape the sweeping tide of the times?In the abyss, the reverse realm, the skins, the alien gods, the mad king, the rulers, and the dark creatures, all howl in madness!Inside the black mist, the demons and ghosts crawl forward as a cross-dimensional migration silently brews.

Do you know how this world ends?
