NOH YIHUN (5)

"I LEVELED UP!"

"Congratulations, Taesan Hyung-nim," Yihun said sincerely. He may have looked and sounded indifferent, but he was really happy for his partner. "You've finally become a C-Class Esper."

"I can finally enter dungeons!" Lee Taesan said excitedly. "Yihun-ah, I'll become an Esper you can be proud of!"

Hmm.

To be honest, Yihun didn't really get it.

D-Class and F-Class Espers weren't allowed to enter dungeons— they were only trained to fight monsters that had come out of a Dungeon Break.

Unless it's an emergency, of course.

C-Class Espers were allowed to raid mid and low-ranked dungeons as long as they had a B-Class Esper with them.

A-Class Espers were allowed to raid dungeons without other classes with them.

Then, finally, S-Class Espers— both natural and not— were allowed to raid dungeons on their own.

But, to be fair, only the Top 5 Espers had the guts and abilities to clear a dungeon alone.
