Samurai vs. Science

Synopsis
Boruto and Mitsuki rush to the arena, having been selected as the next match. As they're not present when their names were drawn, Shikamaru recommends not giving them special treatment, so they're disqualified. Wasabi informs Tsubaki she's next. Namida cheers for her as well. Tsubaki is committed to showing the results of her growth. Denki prepares himself, thinking how he and his team-mates have changed since starting at the Academy. Boruto and Mitsuki arrive at the arena, and Sarada angrily informs them they've been disqualified. They realise they would have had to fight each other, and wish they could have done it. Sarada tells them the last match is between Tsubaki and Denki. Denki enters to arena wearing a power suit of his making, confusing many spectators. Naruto is interested in the pitting of samurai against science. Denki's confidence makes an impression in Tsubaki. She makes the first move, but Denki's power suit allows him to quickly analyse her movements and react accordingly. He uses a pseudo Lightning Release they recognise from the previous Chūnin Exam with his suit. Katasuke excitedly explains that Denki's suit uses Lightning Release to stimulate his reflexes. Mitsuki asks if he feels embarrassed considering the previous exam. Iwabee recalls that the person Denki least wanted to fight was Tsubaki, over his limited data on how samurai fight as opposed to shinobi. Still, he remained confident. Denki goes on the offensive, so Tsubaki dodges a heavy blow that surprises everyone. She acknowledges his power, and apologises for underestimating him. Tsubaki recalls overhearing Namida and Wasabi before the exams, how they didn't want her to go back home, but deciding to cheer on her for bringing pride to her people back in the Land of Iron. Tsubaki and some of the spectators notice that Denki's attacks are getting more precise. Denki manages to land hits and throws Tsubaki up in the air, where he aims a fireball at her. She slices through it, and back on the ground, she manages to land an attack made in desperation. Tsubaki wants to test something, and begins attacking Denki not only with her sword, but also her sword's sheath. She's able to destroy Denki's visor. Katasuke explains the visor contained a motion sensor to help Denki predict her movements, which Sarada compares to the Sharingan. The rest of Denki's suit begins to overheat. Tsubaki commends him on what he's achieved so far, but he refuses to give up. He dodges her attack, allowing her to destroy his suit, which surprises her. Denki enhances his movements with the Lightning Release from earlier on his own, and uses the last of his chakra to land an attack on Tsubaki. She is knocked unconscious, and Denki is declared the winner. Denki's father cries overjoyed watching the broadcast. Metal and Iwabee celebrate. Denki's victory inspires Katasuke to create new tools. Konohamaru formally announces the four victors as chūnin as their team-mates cheer on them. Tsubaki wakes up in the infirmary, and confesses to her team-mates she let her guard down when she learned Denki would be her opponent. She also says she didn't consider their feelings, and reveals her intention to request an extension of her stay in Konohagakure. On their way back to Sunagakure, Team Shinki discusses their mission to observe Kawaki, and Shinki admits he wanted to see Boruto's match. The new chūnin celebrate with their friends, team-mates, and families. At home, Naruto asks Kawaki his opinion. He thought everyone was too desperate to win, but thinks it's not too bad to start as a genin. Boruto and Mitsuki decide to have their match by themselves at the arena that night.
