Rescuing Naruto!

Synopsis
Mitsuki wakes up in the hospital, remembering he wanted to protect Boruto, but is still too weak from Urashiki's attack. Sarada informs Mitsuki of how things turned out after he was attacked. In a wasteland where a God Tree resides, Momoshiki drains Kurama's chakra from Naruto. Kinshiki explains that this God Tree was created from a man who also harboured a Tailed Beast, who Naruto understands to be Killer B. Momoshiki complains about how long the process is taking, having only absorbed half of the chakra in Naruto. Naruto says he won't make it easy for them, that as shinobi, they've had to persevere to develop their abilities. Momoshiki explains how they're able to effortlessly acquire power, which Naruto links to the Shinobi Gauntlet, blaming himself for ignoring Boruto to the point it drove him to rely on the Scientific Ninja Tool. Momoshiki resumes extracting his chakra. The other four Kage arrive, interrupting Momoshiki, and cutting Naruto free from his restraints. The Kage fight Momoshiki and Kinshiki while Sasuke and Boruto check on Naruto. Naruto notices Boruto is wearing his old clothes. Naruto apologises for ignoring Boruto, sharing a bit of his own mischievous past. Boruto asks Naruto to tell him his story after they go back home. In Konoha, Shikamaru instructs other shinobi to make sure no one else is missing, and to be on the lookout for Urashiki. Shikadai asks him if they shouldn't send reinforcements. Shikamaru sees his concern for Boruto is like his for Naruto. He explains their current situation using shogi analogies. Sasuke fights Kinshiki, who has to dodge an attack from Chōjūrō instead of landing a hit on Sasuke. Chōjūrō allows himself to be hit, so a concealed Kurotsuchi can land a hit on him, sending him flying for Sasuke's strike. Chōjūrō and Kurotsuchi pin Kinshiki down. The others focus on Momoshiki, Gaara using his sand to offer others footing while pursuing him. Boruto warns Naruto of Momoshiki's ability to absorb and amplify any ninjutsu used against him. Momoshiki notices Kinshiki has been incapacitated, and upon checking Boruto with his Byakugan, notices how Naruto is unable to pass on his power to him, and offers to show how his clan does it. He converts Kinshiki into a chakra edible and consumes it, Sasuke attempts to strike him but fails. Momoshiki's appearance changes, including manifesting a third Rinnegan on his forehead, and tells Naruto he's next.

Trivia

 * The episode has a number of differences from Boruto: Naruto the Movie including:
 * As Momoshiki is draining Kurama's chakra within Naruto like in the movie, the anime allows Naruto to realise that he didn't acknowledge everything Boruto had tried to authenticate, such as how Boruto believed he awakened the Byakugan and later broke his son's promise to personally come to Himawari's Birthday. All this made Naruto feel guilty for treating his son like a kid, and having pushed him to use the Gauntlet during the Chūnin Exams, giving Momoshiki an advantage in absorbing the Gauntlet's power.
 * While Naruto didn't get the chance to apologise to Boruto in the movie, the anime allows him to apologise this time for ignoring his family and unable to understand him just to focus in protecting everyone in the village, and reveals his mischievous past to Boruto.
 * In the movie, Kinshiki requests Momoshiki to kill him so that he can get stronger. In the manga however, Momoshiki does so on his own accord. The episode follows the manga depiction, but also adds an extra line of Kinshiki who voices his willingness to be absorbed like in the movie.
