I'm thinking the best way to win is to let Aya live, but ruin her reputation, let her know he will kill her family if she talks, and have her disfigured from the torture. She'll never live a normal life (plus she'd have to do underground work to pay off the debt, so she might "disappear" to her famiiy.)
If she lives on and suffers, that's better than killing her.
I assume the game people know how to threaten someone with "talk and you die horribly in some third world country's snuff film sex slave ring." Aya would have to stay silent about how she got hurt and was captive.
That would be a great ending. Take away ALL her power and she suffers. Eyama can use the money to destroy his other bullies. (1 million dollars can get you some great thugs to beat THEM up every week.) And maybe he gets to be a supervisor for the next prison lab.
Ookay at first I thought that he killed his partner then comes amazing plot twist, not dissapointed just wanted that female bully to die... But then it would ruin the game. Still, I want her to die a very painful death.
