Boruto: Naruto Next Generations • S01E85 : Heart of Stone
To release himself from the barrier, Boruto desperately searches for the Heart of Stone, but is still unable to locate it. At that point, a member of the Genbu sannin-shu (Genbu Shinobi Trio), Sekki, a genin who came for the Chunin Examinations the other day, appears. Sekki is also here at the training ground for his own Heart of Stone, but is also having trouble finding it. The two cooperate with Ohnoki, and continues the search.
