Failed explorers (Pixiv Fanbox)

The lower levels of the dungeon are quite dangerous, with all sorts of monsters and creatures freely roaming around that not even we really know about. Sometimes trainees who happened to be adventurers before their time at the dungeon willingly venture down in order to map the dungeon and have some fun during their time off. Often, those trainees completely overestimate the dangers lurking beneath and manage to get themselves captured in the depths of the dungeon. Due to safety concerns, we sadly cannot send any dungeon staff after them, so the captured trainees will have to endure whatever they’re exposed to until another brave adventurer manages to free them~ Depending on how far they got, that may take months or even years though...
