The story follows Haruki and Karen as they embark on a hot spring trip that quickly shifts from relaxation to excitement when they join a hunt organized by Kagemitsu. While Haruki feels rejuvenated by the hot springs, the adventure intensifies when he meets a shrine maiden en route to Kamuykotan for prayer. This encounter introduces a new dynamic to their journey, raising questions about her role and impact on the unfolding events.

A FIGHT TO THE DEATH Haruki and Karen have almost completed their request! With Ooiso safely in their care, all they have left to do is leave the dungeon–but that’s easier said than done. Just as they reach the gate, they run into Shikama and his unsavory crew, and a monster swarm. Haruki is left with only one logical choice: fight like his life depends on it…because it does!

Based on the prize-winning web novels in Japan! In a time when dungeons and monsters have appeared in our world, a struggling modern adventurer finds a fantasy dungeon–and a special treasure–under his Hokkaido home. Since the discovery of fantastical dungeons all across Earth, slaying monsters and clearing out dungeons has become a popular pastime. Twenty-seven-year-old Karaboshi Haruki dreams of gaining recognition as an adventurer, but he's got two monstrous problems: he's socially invisible and has literally no skills at adventuring. When a dungeon suddenly appears in his garage, however, he finds a skill board that allows him to level up faster. The dungeon-diving adventures Haruki has always dreamed of are just getting started!

Leveling up. Haruki might be invisible, but he makes up for it with courage and his secret skill board, which has proven its worth with countless dungeon spoils while his skills are growing day by day, Karen's have a long way to go. Can Haruki and his skill board help her level up, too?
