"Mitsuki's Will" (ミツキの意志, Mitsuki no Ishi) is episode 72 of the Boruto: Naruto Next Generations anime.
Uō and Saō are attacked by foreign shinobi while guarding one of Konoha's gates at night. In the morning, Sai checks in on the police investigation and finds a Konoha forehead protector by the site. Sarada notes Mitsuki is late, and doubts Boruto when he says he's probably still at home. They decide to go tell Mitsuki their missions have been cancelled in person. When they arrive, they find his door open, so they enter his empty apartment. Boruto finds it depressing, and the two consider how Mitsuki never spoke of parents and his home village. They see a portrait of Boruto by his bed. Boruto asks the other genin if they've seen Mitsuki. Inojin thinks Boruto would know where to find him. Chōchō says all the jōnin have been summoned by the Hokage, even when most missions were cancelled that day. Boruto and Sarada inform Konohamaru that Mitsuki is missing, and notice he's hiding something when he brushes them off. Boruto and Sarada eavesdrop on a high-level meeting, where they speculate who might be behind the attack on the guards and why. Tsunade arrives, having heard of the attack. Sai has Konohamaru confirm the forehead protector he found is Mitsuki's.
They consider Mitsuki might have been the target, while Tsunade is unaware of who Mitsuki is. Because of the situation, they also call in Homura and Koharu. Ino checks the guards' memories of the attack, and sees Mitsuki leaving with the assailants on his own. Boruto and Sarada don't know what to make of it. Konohamaru considers Mitsuki might have an ulterior motive, and suggests contacting Mitsuki's guardian. Naruto reveals to those who don't know that Mitsuki is Orochimaru's son. Tsunade is angry and the advisers consider Mitsuki to be as dangerous as Orochimaru. Naruto says he's accepted Mitsuki as a shinobi, and Shikamaru adds that Orochimaru's research will be important when fighting the Ōtsutsuki. Boruto and Sarada discuss Mitsuki's loyalty, and how there is much they don't know about him. Sarada says that as shinobi, they must consider every possibility. Boruto wonders if the Hokage Sarada wants to be just has amazing skills. He then admonishes her for not giving Mitsuki the benefit of the doubt before leaving. Shikadai informs Boruto the village is under increased security alert, that a tracking team is being assembled to look for Mitsuki, and warns Boruto not to do anything stupid. Near the attack site, Boruto finds one of Mitsuki's snakes being attacked by the remnant of one of the attackers. Boruto defeats the remnant, and the snake relays a recorded message to Boruto that this is Mitsuki's will. At night, Boruto prepares to leave for find Mitsuki and confirm his message. Despite the danger, Sarada joins him, and wants to take the snake to Orochimaru to get more information about it.
