At the beginning of the match with Seishou Gakuen, Outei Tsukinomiya immediately started to play rough and Kusaka shot to Sasotsuka Eiji. Later he scored the third goal for his team. The match was forfeited when Sheishou wasn't able to play and Outei won with three points. When they came to Nosaka Yuuma to talk about Ares program, Kusaka was talking on behalf of the team that every time they saw other teams played, their hearts ached. They wanted to be able to run freely and kick the ball, that was how they felt now. They understood what real football was, playing in matches in the tournament.
During the match with Inakuni Raimon Kusaka said that they figured out how Grid Omega worked and Nosaka responded that now they didn't need to use it anymore, which surprised Kusaka. Outei Tsukinomiya started to counterattack and Kusaka was running toward the goal with Haoto and Nosaka, stated that they would scare Raimon now. Right after they used their tactic Rogue Press, which was blocked by Inamori Asuto. Kusaka was wondering what kind of instructions gave them their coach but it was shown that Zhao Jinyun didn't tell them anything. Kusaka was shocked with the power of Kozoumaru Sasuke’s shot Hidaruma Bakunetsudan which Nishikage Seiya wasn't able to stop.

Kusaka was present at the ceremony where the members of Inazuma Japan were announced but he wasn't selected as a member. He was sitting at the stands with Haoto Ichiya who was wondering if Nosaka was watching the ceremony. Kusaka stated that he should be now on his way to America.
Kusaka was seen later during the meeting with Nosaka and Nishikage Seiya, before they left to Russia for the FFI tournament. It was revealed that after the departure of Midouin Munetada, the Ares system was finally closed. The team got the chance and was rebuilt so the players returned to training.
