After the rules have been put both Harvis and Kazuki got in a mini arena
Where in front of the room the tables were removed once Harvis and Kazuki both step in the mini arena when they do so a barrier starts appealing around them not visible but made out of raw soul then Covrin starts explaining
Covrin: "well this barrier here will keep all the soul presence and damage inside the barrier where only the souls inside the barrier are affected well let's see the duel now shall we"
That moment with a deep breath Kazuki smirks and release his soul presence forming an light red aura around him quite warm he feels it how the hole barrier is slowly getting filled with his soul energy the moment Harvis saw that before his eyes he realized how much he fucked up he had no experience in battle Harvis didn't even knew how to release his soul energy Harvis was stunned his empty face was no longer there he started feeling all the chaos and consequences incase of failure Harvis was shaking not scared but stressed Harvis thought
"No no no no no I can't lose I need to do something for gods sake this can't happen no"
Then Kazuki starts talking
Kazuki: "sorry prodigy kid but your fame ends now"
Then Kazuki starts manipulating his soul energy and uses his technique that he names
'The Forty kunais of art'
in that moment around Kazuki in front of himself 40 different kunais made out of Soul energy all of them different unique fonds and all types of shapes in different shades of red all kinds of shades at that moment the public was looking fascinating by it all while Covrin smile was becoming bigger and bigger.
