"I will become a hero!"

With that dream in her heart, Shirumiruku Eru became an adventurer. But because she had no special skills, she struggled to find companions. That's when she got the chance to join the dungeon investigation led by Yuris, a great sage who specializes in healing. However, rumor has it that all adventurers who accompanied Yuris have had their spirits broken and abandoned their path as adventurers halfway through... You see, Yuris had a bizarre interest in getting excited by the sight of female adventurers being attacked by monsters.
