April 2028, I’m still in the dungeon today. Kaito Takagi dives into the dungeon every day instead of doing a part-time job. Mob character Kaito is an explorer who hunts slime every day and could only earn a meager amount of pocket money. The others calls me a slime slayer (LV3). In the past, I tried to hunt goblin and I escaped for my dear life. A golden slime that I had never seen since I became a Slime Slayer (LV3) appeared, and when I kill it, a rare item called a servant card was left behind. It is a dungeon exploration tale of a poor mob character … maybe.
