On the last episode of Boruto: Naruto the Next Generations we found out that Konoha is in the midst of an age of modernization, which brings with it vast wealth disparity and people are angry about that. But since Naruto is in Denki's shitlord dad’s pocket, he naturally sides with him over the townspeople of Konoha.
So anyway, cue the catchy ass intro music!
Ok, so we're on the train and Shikadai's like "Snap out of it, Ryogi, or we'll have to anime fight!"
And then the Byakuga Gang Leader is like "I would have gotten away with it if it weren't for you meddling kids!"
And then Shikadai's like "Are you the one giving Ryogi stupid ideas!"
And the leader is like "My ideas aren't stupid you're stupid!"
And then he's like "You're just a stupid child. Go home."
And Boruto's like "You think you can persuade us to leave with your fancy talk!?"
And then Boruto throws some ninja stars at him but Ryogi blocks them and is all "He saved my life once and for some reason that explains why I never noticed that he's clearly evil!"
Then Shikadai's like "Is that the life you hoped for?"
Then Ryogi whines about how no one understand what it's like to be him. Crawling etc etc etc.
Then Shikadai's like, "That's stupid. You're stupid. You remember all those times we played Shogi together?"
And then Ryogi's like "I was faking it!"
Then for some reason Ryogi gets a headache and then uses ice jutsu to make a wall between him and Shikadai.
Then it turns out the reason he never realized the Byakuga gang leader was evil is because he's being brainwashed.
Then it turns out Boruto is being brainwashed now too and thinks Shikadai is a Byakuya gang member.
Then Shikadai uses kunai to break the ice and is like "Like I'm gonna be shoved into a mold that's too tight!"
Then back to Ryogi, who drops his shogi pieces and the Byakuga gang leader is like "Did you get those from your boyfriend?"
Then he throws them out of the train like a douche, then he's like "Go have an anime fight with that black haired kid."
Then back to Boruto and Shikadai and Boruto almost stabs Shikadai in the face, but he uses his shadow jutsu thingy to stop him and is all like "How weak are you to brainwashing?" and then Boruto's like "Was I brainwashed?" and Shikadai's like "No shit, Sherlock." and then punches Boruto in the face.
And then cut to the Byakuya gang leader who kills one of his faceless goons because he's evil.
And then cut back to Shikadai and Boruto where they talk about how they shouldn't go have an anime fight with the bad guys but will anyway.
Then they go to the next car where Ryogi shoots icicles at them but they decide not to do fight the miniboss and go straight for the final boss, but then Ryogi jumps up onto the top of the train with them.
Then Shikadai's like "Boruto, you go on ahead and fight that other guy all by yourself. I'm going to stay here and make out with Ryogi."
Then cut to the Byakuya gang leader who is going to detach the engine from the cars but Boruto stops him.
Then back to Shikadai and Ryogi and Shikadai uses Talk no Jutsu, but it was not very effective.
Then for some reason the brainwashing on Ryogi gets stronger and he thinks Shikadai is the person that killed his parents.
Then cut to the Byakuya gang leader and Boruto and the leader is like "Let's use the Talk no Jutsu instead of having an anime fight."
And then he's like "I surrender, but not really! Evil psych-out!"
And then he kicks Boruto in the face and then detaches the engine from the rest of the train.
Then Shikadai uses Talk no Jutsu again and it's super effective.
Then Boruto uses his wind ninja magic to launch Shikadai at Ryogi and break the brainwashing.
And then Ryogi's like "Sorry."
And then Shikadai's all "I don't understand what it's like to be you, crawling etc etc etc, but I'm optimistic about the future because of a shogi metaphor involving pawns.
Then Boruto's like "The evil guy got away."
Then Naruto shows up, having waited until the last minute when Boruto and Shikadai have done all the hard parts to step in and stop the Byakuya gang leader so that he can take all the credit like the piece of shit that he is.
Then time skip to a few days later where Shikadai is in the park playing Shogi. The Byakuga gang leader and Ryogi are in jail, never to be seen or mentioned again after this episode and Boruto returns the scroll thing to that one scientist guy.
Then Boruto shows up and talks about how long it will be until Ryogi is released from prison (Shikadai says he doesn't know but I think we all know it's never) and what an asshole Naruto is.
Then Boruto's like "You still owe me a burger for helping you save your boyfriend's life." and Shikadai's like "Oh yeah, I forgot. What a drag."
And then catchy ass ending music. And that’s the end of that arc.
