Idk about anyone else but I got major flashbacks during this scene. It's getting to the point where I'd rather Denki stops Boruto now. He should have never showed his Vanishing Rasengan. All I'm saying is that im happy it's not Shikadai that Boruto is fighting in the flash forward. Round 4 is among.
I hope Lord Shinki of the desert shows up like this sometime this arc and solos someone. We need way more Lord Shinki in our lives. He can be around in future arcs to solo Sarada & Mitsuki like Shikadai is for Boruto. If there doing anime original arcs then he deserves one for character development.
