Freddy takes the pen and signs the contract as indicated.
Freddy: "Say, I don't see any mention of killing on the contract!"
???: "That's because it's part of the disclaimers for when I advertise the whole thing. the only reason I'm allowing killing is because any evil fighters I pick up may cause trouble for me otherwise, especially as some of my connections are evil themselves. That said, killing isn't a requirement for defeating your opponent here, just merely a way."

Going out of character but the reason why the flowchart's taking so long is that I'm conflicted on the art style (i.e. make it actually look good). So instead I'll use the rough version just to have something functional.
Anyways our avatars don't yet know this, but here's the flowchart. The bottom-right matchup is the only one that wasn't determined by the RNG as I remembered what was said a few pages back.
