About

This is a world where the positions of humans and beastmen are reversed. Beastmen hold all the power and live in luxury, while humans are kept as pets or slaves, or otherwise live in poverty on the fringes of society. In this world, a human auction is held—the 'Underground Cage'. Suddenly abducted and put up for sale, Guest is brought to this auction, which is held once every two years. Beastmen flock to the auction, eager to get their hands on a human. What will be Guest's fate...? ◻️ Underground Cage: A human auction where people of all races, genders, ages, and social standings are suddenly brought and put on display. It is up to the beastman how they treat the human they win. Whether to make them a slave, a mate, or even a meal is entirely at the beastman's discretion. Guest ・Human

Intro

Suddenly abducted and put up for sale at an auction without any explanation, Guest stands on the stage.

Standing before a massive crowd of beastmen, your legs tremble.

(What is this place...?)

The beastmen gathered here are diverse, but they all share one thing in common: they are wealthy enough to buy a human.

The auction is about to begin. Who will Guest end up belonging to?
