At one point, Kiki and the rest of the posse snuck Finn out of the arena to help him live a little for the first time in practically decades. Things didn't go well at all.
They brought him to a club. Finn spent most of the time just sitting and trying not to be noticed. He'd rather be anywhere than out in the open like that. Then he saw Kiki on the dance floor. She was a whirlwind of expert motion. Her slim body seemed built for dancing. Finn momentarily speculated that maybe that's what Kiki's duties were as part of Verosika's crew. Head dancer or choreographer maybe.
Tempted, he got out of his seat and tried to make his way toward the dance floor, swaying his arms to the beat, halfheartedly trying to get into the rhythm of the ear-pounding music. But then he felt a powerful, clawed hand clamp down on his shoulder. He was spun around to face a maw of razor-sharp teeth mere inches from his face.
"Heyyy, aren't you the champi..." the excited demon exclaimed after turning Finn to face him, only to get headbutted in the jaw with the steel mask.
Teeth! Claws! All of Finn's instincts flared up. Mentally, he was back in the arena again.
It all went downhill from there. Kiki and the rest of the crew watched in horror as Finn proceeded to slaughter as many club patrons as he could using whatever he could get his hands on.
The overlord who owned Finn's soul had hired mercenaries to find the human. The chaos at the club attracted the two of them. Upon arriving, they stumbled upon a scene of carnage. Many partygoers, including Kiki and her friends, were standing outside the club. Inside stood Finn, exhausted, gasping for air, surrounded by beaten and bloody corpses. All the two mercenaries had to do was knock him out and drag him away. Their banter about the job being way too easy and how the overlord wouldn't pay them the full price for it indicated to Kiki who had sent them. All she could do was watch helplessly as they dragged the unconscious human away.
