Boruto: Naruto Next Generations 184. Bölüm (Puppets)

The Hidden Leaf had lost contact with Konohamaru and Mugino. With Katasuke and the ninja hound Chamaru in tow, Team 7 inspects the crash site the two jonin were investigating, hoping to find clues to their whereabouts. Instead they find the mysterious puppets, identified by Katasuke as incredibly advanced Scientific Ninja Tools. After a brief fight in which the scientist's knowledge proved instrumental against their mechanical enemies, the group manage to locate Konohamaru and Mugino in a cave. But their reunion was interrupted by the arrival of an unexpected foe, Ao. The Outer attacks them, prompting the injured Mugino to sacrifice his life in order to collapse the cave on Ao and himself, using Earth Style. Though the others manage to escape, Ao soon digs himself out as well. (Source: Wikipedia) Ao Arc: (7/10)
