Kama

The derelict building buckles beneath the toad's bulk, and Ao spends his last effort on a Water Release wave that shoves Boruto clear of the falling wreckage, only to be crushed himself. Koji Kashin puzzles over what drove Ao to reach for ninjutsu in his final moment, then dismisses his summon and introduces himself, praising the fight he watched and needling Boruto by mocking Ao's feelings. Konohamaru presses him for details about Kara, but Koji gives nothing away.

Koji binds their movements with a sealing technique and prepares to burn them alive, yet Konohamaru shatters the trap with a release seal of his own. The two square off, with Koji parrying and evading the jonin's taijutsu and Fire Release alike, then stunning everyone by answering Konohamaru's Rasengan with a matching sphere.

Koji sets off a toad he had planted on Konohamaru, engulfing him in flame, but the mark on Boruto's hand flares and spreads, drinking in both the seal and the fire and dropping Konohamaru. Koji recognises the pattern as Kama and marvels that Boruto is the one Momoshiki chose. The boy watches the seal creep up his arm before losing consciousness, and Koji withdraws, thanking them for the spectacle. Sarada moves to wring answers from him, but Mitsuki restrains her rather than gamble with their comrades' lives, and Koji, aware Mitsuki's parent is Orochimaru, commends the caution.

Once recovered, the group raises a grave for Ao and turns over their questions about Kara. At the hideout, Amado reviews his files and notes that Koji and Boro have yet to be cleared of suspicion, and while he steps away, Delta slips in, judges the other two innocent, and pins the role of traitor on Koji. Heading home to report, the team stumbles on the ruins of a fiercer puppet battle and a collapsed boy nearby, whom Boruto approaches to find carrying the very same mark he now bears.
