He begins the match violently by aiming his technique Execution Method 13: Guillotine at Marui's face. However Marui and Kite overcome this and take the lead.
With Marui taking the spotlight with his Tightrope Walking, Kimijima The Negotiator begins his negotiation by goading Marui into hitting the Tightrope Walking again.

Kite and Marui are able to bounce back and show signs of being able to fight back. It is then shown through Marui's own flashback that secretly unbeknownst to the rest of the Camp including Tohno that Kimijima wants Kite to attack Tohno's weak right knee and end his career.
Tohno arrogantly plays and is said to have gone beyond 60% according to Kimijima. Tohno begins his execution Methods and begins to attack Marui mercilessly. Marui is able to endure the attacks however he is completely unable to attack and only defend. Tohno accedentally throws his racket into Marui's eye whilst getting carried away, injuring his eye meaning Marui can no longer defend. Kite decides to sacrifice himself as means to atone for what he did to Marui and It is then revealed that Kimijima also told Marui about Tohno's weakness in his knee.
In the final game of the match as Kimijima/Tohno are going to take a comfortable win whilst Kite is left on the floor in a bloodied state by Tohno's Execution Methods unable to play, Marui decides to hit a shot into Tohno's right knee and seemingly end his career.
