Mitsuki's Friend

After walking out of the village, Mitsuki links up with Sekiei, Kokuyō and Kirara, quizzing them about the Akuta they travel with and whether meeting the creature's maker might resolve his questions about free will. When Uō and Saō discover the group, Mitsuki strikes them down but only fakes their deaths, leaving a snake behind carrying a message for Boruto. In the present, he coaches Sekiei on ordinary human habits during their trek toward the Land of Earth. Sekiei's body starts to deteriorate, prompting Kokuyō to head off for help and leaving Mitsuki to watch over the ailing artificial human, whom he tries to lift by offering flowers.

Explaining meals and dental care to Sekiei, Mitsuki drifts into talk of their respective makers, Orochimaru and Kū, and of death itself, wondering what could ever make him weep. Sekiei suddenly ambushes him, clamping an explosive centipede around his neck and pressing him about the snake and the staged killings. Mitsuki reveals the note simply tells Boruto he left of his own accord. Asked how he regards Boruto, he calls the boy his sun and admits he cannot be sure whether the feeling is his own or something planted in him. Kokuyō returns with Kakō and Kirara, who stabilizes Sekiei, and when they move to knock Mitsuki out, Sekiei wakes and vouches for him, framing their shared secret as the mark of true friendship. In Iwagakure, Kurotsuchi is held captive as Kū mass produces more Akuta.
