World's Fastest Level Up (Manga) Vol. 8

MOVING UP THE RANKS Now a trial member of the prestigious Yoizuki Guild, Rin has the opportunity to dungeon dive with some of the top adventurers in the world. Placed with an A-rank party, Rin can't wait to see what kinds of rewards he'll get in the more difficult dungeons. But on a routine dive, he and his fellow adventurers encounter something extremely odd-monsters who come back from death! Can Rin help them out of danger, or is he simply deadweight?
