This S-Class Dungeon Is My Home

Summary

The day my biological parents finally "reclaimed" me from my middle-class life, they didn't throw a homecoming party. Instead, they packed me up like a piece of unwanted cargo and tossed me straight into a high-stakes horror trial—all to serve as a human shield for their precious, adopted daughter.

My birth parents had spent a small fortune on a rare soul-binding artifact. It linked my life force to Tiffany’s, ensuring that any physical harm meant for her would instantly transfer to me.
