10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”. However, not all Hunters are powerful. My name is Sung Jin-Woo, an E-rank Hunter. I’m someone who has to risk his life in the lowliest of dungeons, the “World’s Weakest”. Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled dungeons… at least until I found a hidden dungeon with the hardest difficulty within the D-rank dungeons! In the end, as I was accepting death, I suddenly received a strange power, a quest log that only I could see, a secret to leveling up that only I know about! If I trained in accordance with my quests and hunted monsters, my level would rise. Changing from the weakest Hunter to the strongest S-rank Hunter!

In the eyes of many people, Hefpaff College represents a mediocre idiot, while Slytherin is famous for its shrewdness, ambition, and sleekness.

When Hefpaff stayed with Slytherin, it was like a badger and a snake in the same room, and it seemed that badgers would always be bullied by snakes.

Compared with the dazzling other three hospitals, Hefpaff is mediocre, so many people forget Hefpaff’s academic spirit: integrity, loyalty, honesty, and fear of hardship. People who possess these qualities may not be in harmony with each other. Tom Riddle was equally famous, but their souls were stronger than him.
