Mitsuki's Disappearance Arc

Main article: Mitsuki's Disappearance Arc The day after a Five Kage Summit was held in Konohagakure, Kokuyō and Sekiei attacked Saō and at the village's entrance, leaving both men in comas, before leaving with Mitsuki. On their way back to the Land of Earth, Sekiei took an open liking towards Mitsuki as an artificial human. He began talking about how Mitsuki's being would help in advancing their goal, only to be interrupted by Kokuyō, who didn't trust Mitsuki with such information. As they approached the Land of Earth's boarder, Kokuyō noticed that they were being pursued by Konoha-nin. Sekiei was sent ahead with Mitsuki while Kokuyō engaged the pursuers. He quickly dispatched the chūnin, and then met a group of Konoha genin who were unofficially pursuing Mitsuki.

He made his views and goals clear as he began berating the children. Showing value in his self-worth, the artificial human quickly pressured the genin with his inhuman raw might. After being impressed by their team-work of Boruto Uzumaki, Shikadai Nara, and Sarada Uchiha to take out an Akuta, he decided to start fighting seriously. The genin were saved by the timely arrival of Chōchō Akimichi and Inojin Yamanaka. With the team together, the Ino-Shika-Chō decided to hold off Kokuyō while Sarada and Boruto went on to find Mitsuki. Despite the team's perfect formations, Kokuyō easily repelled them all, forcing them to retreat. Kokuyō then rushed to catch up with other Konoha-nin. He arrived in time to see Sekiei struggling against Boruto's snake summon Garaga. Rather than help, he decided to see how things would play out first. He watched as Mitsuki came to the weakening Sekiei's aid and made his intention of joining the artificial humans clear as he struck Boruto hard with a Lightning Release. In watching the unhesitating action of Mitsuki against his former team-mate, Kokuyō came to trust Mitsuki as the group left the Konoha-nin, finding them too pitiful to bother killing.

Later, still having some concerns about Mitsuki, those thoughts were forgotten as Sekiei's body began breaking down. Taking a chance, he left Mitsuki with his weakened ally and returned to base for help. After getting help from Kirara and Kakō, they returned midway to find Mitsuki carrying Sekiei. As Kokuyō the others continued to grow suspicious of Mitsuki, the partially treated Sekiei vouched for Mitsuki, insisting that the boy truly came of his own free will on the goal of learning who he truly is.
