Mitsuki's Disappearance Arc
Kakō went to see their leader, Kū, with Kirara, who returned to give their leader her report. He even asked Kirara if she made a mistake during her mission and blames her while talking about Kokuyō and Sekiei being late, much to her irritation. Kakō said there was no need to make excuses to him and stated their leader would pass judgement.

When his leader Kū began his power move against the Fourth Tsuchikage, Kakō aided him in capturing the village leader. After the successful abduction, Kokuyō return seeking help for the weakening Sekiei. Kakō and Kirara joined him to help. Midway, they found Mitsuki approaching them while carrying Sekiei. While Kirara and the others grew suspicious of Mitsuki, Sekiei vouched for Mitsuki, insisting that the young boy truly came of his own free will to learn who he really is.

Once arriving at their headquarter, he discussed with Kokuyō how best to deal with Mitsuki, as the plan ultimately was to dissect him. Kokuyō however calmly said they would wait for orders. After Ōnoki, the mastermind behind everything, went missing, Kū had Kakō and Kokuyō use more Akuta to search for the elderly man. Later, his body began breaking down, requiring treatment.
