"Ah, very well."
Itachi leaves the room for a brief moment, returning with two metallic vests with Velcro at the ends, allowing one to fasten it around their chest. Two light-blue neon circles shined on both the right and left sides of the front. He throws them at the two participants feet for them to pick up. When worn, one would feel a brief moment of unconsciousness, awakening in a completely different but exactly the same body one second later. They appeared just as they did before they wore the vest, and their original selves stand lifeless
"Nyehehehe, let me be the first to introduce you to the Ouro Corp Patented Mito-Guard aka Second Life! With this, meaningless bloodshed will be a thing of the past! Lemme tell you, one day wars will be fought and won using these, and everyone will be none the worse for wear. Ah, but, uh, I should note first that you should make sure your original body is safe after using these. If accepting your own mortality is more your style, you can always take the vest off your body and return to normal."
He scratches the side of his scalp for a moment. With that out of the way, he starts writing in a notepad he was carrying and waits for the participants to begin their match. Once they entered, they would see that the arena itself looked like the picture Yu had posted in the Tournament Discord Channel.
