Club guy should run at an angle around the black hole guy so Club guy goes back in time. Keep doing so until you are at Black Hole guy's childhood. Tell him he will meet three people later in his life that he must betray, Cloud guy, Gear guy, and Rice guy. He must stick by them until he battles Diamond guy and Club guy. At which point he should kill all three of his supposed allies.
That's a great idea! Except black holes don't work like that and time just slows down a bit. You get picked up off the ground by the gravity...
