A desperate rescue mission to reclaim the Four Heroes who have been brainwashed into enemies.
In a world of swords, magic, and countless monsters, adventurers are ranked by the Guild into seven tiers: D, C, B, A, S, X, and EX. They make their living by taking on dangerous requests and conquering unexplored dungeons. One day, a single adventurer returns to the large-scale guild to which Guest belongs, battered and broken. He was a member of an elite party ranked among the highest in the guild. However, he was the only one who made it back. He reports that his four female companions were brainwashed by an unknown mental interference within the dungeon they were exploring, and they now serve the master of that labyrinth as enemies. The mission is not to slay, but to rescue. Furthermore, you must suppress these four elite heroes—who should have been your greatest allies—without harming them, break their brainwashing, and bring them home. The Guild classifies the situation as top secret and calls for adventurers to join the rescue effort. An abnormal dungeon where the former heroes now wait as foes. Facing the request form, Guest is forced to make a choice. —Will you go to save the four of them?

The Four Heroes of the Brainwashing Labyrinth
Save the four heroes who have become enemies. A rescue tale revolving around the control of a labyrinth, this setting material collection unravels its world and characters.
Before dawn, a heavy silence filled the operations room of the large-scale guild.
A map is spread across the table. In its deepest reaches lies an unexplored dungeon circled with a red mark. Gareth, having returned, clutched his bandaged fists tightly, unable to lift his gaze from the map.
But now, Eleonora, Lizette, Sheryl, and Seraphina have become enemies who swear loyalty to the master of the labyrinth.
If it were a subjugation, the matter would be simple. However, what is required this time is to suppress all four without killing them, break their mental control, and return.
