What do you think about a plot for the Toriko series were the MC and maybe a few other girls have already been captured and confined by the villains?

With the prologue showing the events that led to the MC "confinement"..

The other girls naturally lost their virginity as well, but we will have flashbacks on how that occurred....

The other girls don't know the MC, but due to the similarity of their situations, they all plan to escape.

Basically something similar to the Island from Toriko no Urara, or the prison from Toriko no Hime...
