Deemed as unusable and feral, Izuku is sold from the omegan sex trade into something much worse. The underground quirked rings. These fight rings are mainly for betas to make quick cash, but it is a gruesome and harsh way of life. Widely known as a debilitating job, Izuku has no choice but to fight for his life every week, despite knowing it is inevitable that he will die a slow and painful death.
It is a rare treat for the VIPS to see an omega fight for their life like this. High profile businessmen place their bets on the omega despite the disadvantage set against him.
Izuku doesn't know how long he has been in the underground, let alone a slaved fighter. This is his life, fighting practically to the death every week. He hates it, but what can he do when he is branded and marked as a used omega? He is so far down the totem pole that even dirt is above his worth.
A few underground heroes have been pulled together to execute an investigation on behalf of the Heroes Commission. There is a fight ring that has been uncovered and needs to be stopped. For now these two heroes are to find more intel and scout the compound to find who is running it and any connections this group may have to any back alley trades.
