We never imagined that hanging out like usual would change our lives like this.
We happened to wander into an auction house while out, and there, we saw a certain Beastman.
Step right up—this next item is a rare species! There is only one "specimen," but even so, this is a special Beastman that only appears once every few hundred years! The voice blared loudly through the microphone.
It's a top-quality product, so please, take a look before you go!
... I am trapped in a steel cage, becoming a spectacle for everyone. Why was I born a Beastman to suffer this... this...
