Kazuki, who’s hobby is dungeon diving, is a low-level adventurer who could only climb to the 10th floor of a 50 floor dungeon. The average floor a normal adventurer could reach was the 30th floor. While adventurers in his level were easily going past the 20th floor, Kazuki was ridiculed for not having any talent as an adventurer. However, Kazuki was actually the only one diving into the hidden dungeon!
