Synopsis

Edelbreas leads a C-rank raid force into the 'Primordial Core' dungeon, following rumors of it being devoid of monsters after a previous raid. They find the first few rooms empty, causing doubts, but continue to the fifth room which is said to contain a valuable plant monster. Meanwhile, Yubarr, the dungeon's owner, is aware of the raid and prepares to leave, revealing that he spread the rumors to lure people in to be consumed. The intruders they found earlier were from a foreign nation, confirming the rumor was out there.
