Boruto: Naruto Next Generations 186. Bölüm (How You Use It)

Mitsuki, Sarada and Konohamaru corners Ao, while Boruto surprises him and tricks him into taking and using a Scientific Ninja Tool that drains massive amounts of chakra. Just as they seem to have cornered him, Ao reveals his greatest weapon, multiple Mirror Drones, flying disc-like objects that fire powerful projectiles. Konohamaru steps in to save Boruto, and is knocked unconscious. Boruto asks Sarada and Mitsuki to guard Konohamaru and Katasuke, while he uses his quick wit and Paper Bombs to dispatch the Mirror Drones and defeat Ao by himself. Instead of killing him and avenging Mugino however, Boruto makes him realize the consequences of his actions, leaving him to stare at the sky in a resolute state. As Team 7 would celebrate, Ao notices Koji Kashin standing atop the ruins right above him, alerting the Leaf ninja. (Source: Wikipedia) Ao Arc: (9/10)
