Boukenka ni Narou!: Skill Board de Dungeon Kouryaku

Haruki Karaboshi has no presence as far as can be recognized, and so he became an adventurer with only the desire to "stand out." One day, a dungeon appeared under his home in Hokkaido. Coincidentally, he picked up a "Skill Board" with which he can spend skill points to increase his growth rate. Is it possible to become a popular person by obsessively diving into your home dungeon every day?
