The shadows that's weren't able to get in joined together and formed a huge ball around the garage leaving the audience unable to see the fight.
Staz: For months I survived and trained in The Dark Lands, where the world reaches its edges. Losing my sense of sight, I had to either fully utilize my other 4 or simply die. The dark holds many secrets that contain the unknown.
His shadow blending into the dark had already located the presence of his opponent, which led to Staz merging Kisuke's shadow into his sword.
*Kisuke snaps his fingers, and all the red ooze goo on the floor had formed a ball around Staz before Staz could move anymore*

Kisuke: Remember when your shadow "stabbed me"? Well it hit that Jawbreaker and the red ooze started oozing out of me right? Wrong. I imagined that ooze coming out of me, hoping that you would think it was blood. You might be wondering, what is this ooze? Well I will tell you. It is a special concoction of Jell-O I made for this tournament to kill Shinigami, but you were too good. I have also put 8/10ths of a milligram of Batrachotoxin in my Jell-O mix. The poison known as Batrachotoxin is the most potent in the world. This poison is a neurotoxin that attacks the nervous system by depolarizing neurons. This halts brain function and causes paralysis, and it only takes 1 Milligram of Batrachotoxin to kill a man. It is found in Dart Frogs, the frogs that have beautiful color but can kill a man if you touch them. Needless to say, you cannot do anything without your brain, even nullify my creations. I bid you adue sir.

Kisuke: I poisoned my Jell-O to where you cannot think or move. It will wear off in about an hour so see ya then.
*Kisuke walks out of the garage*
