Labyrinth Game Arc
After being captured by Anaguma, he and Rokuro were taken from their Thunder Train and woke up in Ōga's maze. Anaguma warned those who asked against trusting Rokuro. He listened to Ōga's explanation of his experiments, and during the collapsing experiment, he held Anaguma with his legs when he was thrown off after his water threads gave out trying to hold the platform together. Rokuro was able to convinve Kakesu to release his restraints by promising to save her, but he simply dropped Anaguma and ignored Kakesu's fall. When Boruto admonished him for sacrificing others, he made it clear he would sacrifice others to save himself.
