The side story for the post-apocalyptic survival NTR RPG, “Her Corruption in the Apocalypse,” is here.

The story takes place after the escape from the collapsed Mikura City. The protagonist, Mie, and Inotsukuda travel across the ruined wasteland, heading toward a new survivor camp.

This side story depicts the events that occur when they wander into a “Cursed Forest” along their journey. Players must repeatedly explore and decipher mysteries to clear a path through the dense thicket. Deep within the mist-shrouded woods, will they find the “rescue” they’ve been waiting for—or does a new “corruption” await them…?

A short spin-off where survival, puzzle-solving, and immorality intersect. A tale that provides a fresh perspective and new shocks, even for those who have played the main game.
