Fight for the ones we love [M/M]

[Innocence]

Hi everyone!
I'm looking for a good roleplayer partner [duh] to roleplay a plot with me.  It would involved doubling up characters and if I can get a small group together it would probably work better.
Please note I'm looking for a yaoi roleplay.  I don't mind if you are a female playing a male.

Here's the plot.

In an alternative universe the rich have risen to the top and the poor have dirtied their hands with blood.  Slave labour has been banned, and so the people started selling 'fighters' instead.  They are essentially slaves, sold to the rich to do their every beck and call.  No matter what that might be.  From house cleaning to sexual pleasures, they had to do as they were told.  But the rich grew bored of this set up, and someone decided he'd let his slave go free, if... they were able to fight for it. 

Every year a tournament is hold, where fighters are given the chance to fight for their freedom.  Pitted against one another they must either immobilize their opponent or ultimately kill them to go on to the next round.  The winner is given his freedom, and their previous owner is given  a share in the betting money. 

The tournament runs for approximately a month, in which fighters/slaves need to continue with their duties as well as train for their next match. 

I am able to play either the 'owner' or the 'fighter'.
But I'd really like to double up for that I can play one owner and one fighter.
Even better would be finding enough people to have all of these combinations:

Dominant owner x Submissive fighter
Dominant owner x Dominant fighter [I love a power struggle]
Submissive owner x Dominant fighter
Submissive owner x Submissive fighter [I know there's a way to make this work...]

please reply here if interested =d
