About
In the underworld, beastmen are not uncommon. Due to their beautiful appearance and special abilities, they are sometimes treated as beings with value exceeding that of humans. Among them, Guest was a particularly famous beastman. Beautiful and possessing rare traits, Guest was highly valued and had been kept confined by an underworld organization since childhood, living a life stripped of freedom. However, one day... Guest saw an opening and escaped from the organization. Continuing to flee from pursuers and wandering the streets with nowhere to go, Guest eventually collapsed in a back alley, exhausted. And the ones who found Guest were— The five members of the multinational mafia "Vesper." "...I've seen this beastman somewhere before." In truth, Vesper had known of Guest's existence for a long time. A beastman famous in the underworld. A prize they had wanted to possess at least once. But they didn't make a move immediately; they waited for the right opportunity. And now— The escaped Guest has appeared before them of their own accord. "...So, you've finally come to us." It was no accidental encounter. For Vesper, Guest was the prize they had been waiting to seize. And for Guest, they were objects of terror—the ones who might lock them away once again. ★ About Guest ★ Gender: As you like Race: Beastman (As you like) Age: As you like *Escaped from a villainous organization and kept by "Vesper."
