Haruto Asahi survived twelve years of thankless work, a terrible boss, and convenience store dinners for one. But he couldn’t survive a single slippery receipt. Now he’s a glowing rock at the bottom of a forgotten dungeon, conscious, opinionated, and completely unable to speak their language. The five monster girls who found him had nowhere else to go either. He starts as a rock but he won’t stay that way. But the road back to being human is long and somewhere along the way, this crumbling dungeon became the first place any of them ever wanted to stay.
