Synopsis
Karaboshi Haruki is someone nobody notices. He turned to being an adventurer hoping to finally get people to see him. Then one morning, a dungeon opened up right beneath his apartment in Hokkaido. Around the same time, he found a "Skill Board" lying around—something that lets him use skill points to boost how fast he gets stronger. So now the question is: if he keeps going into that dungeon under his house every single day, can he actually become someone people care about?
