Story Summary

Michio Kaga, an ordinary high school student, is mysteriously transported into a hyper-realistic fantasy world where death is permanent and freedom is earned through combat and money. After barely surviving his first battles, he learns the brutal realities of this world — including the existence of slave markets.

He eventually meets Roxanne, a kind yet skilled wolf-girl slave who becomes his partner both in battle and in life. Together, they explore dangerous labyrinths, gain new skills, and build a life based on companionship, affection, and survival.

Despite its erotic nature, the series emphasizes themes of choice, emotional connection, and the struggle to carve out a peaceful life in a harsh world.
