Training Begins!

== Synopsis ==
Boruto approaches Kakashi, asking him to for help making his Rasengan into a Big Ball Rasengan. He promises not to complain during training, but Kakashi considers it impossible for Boruto to use the Big Ball Rasengan, as he doesn't have the Nine-Tails to account for the chakra necessary for that jutsu. Boruto insists that Kakashi helps him train, and demonstrates his Rasengan. Boruto isn't satisfied with the damage it inflicts on rocks, and is impressed by Kakashi's. He is determined not to lose like he did to Deepa again. Kakashi compares Boruto's attitude to Naruto's, and agrees to oversee his training. He checks with Boruto to see how much he knows about nature transformation. He explains that jutsu are made stronger by combining nature transformation and shape transformation, and that the Rasengan uses only shape transformation. Kakashi has Boruto demonstrate his Vanishing Rasengan, and explains to Boruto that it employs lightning chakra. He considers it an incomplete jutsu, and suggests for Boruto to try using wind nature chakra. Boruto's Rasengan behaves erratically at first, so Boruto focuses on increasing his control over it. Sarada asks Sasuke to teach her the Chidori. Sasuke explains that using Chidori makes one vulnerable to counterattacks, and demonstrates by countering Sarada. He adds that with only one tomoe, her Sharingan doesn't give her enough perception to read her opponent's moves, the Chidori requiring at least two tomoe Sharingan to be used. Sarada wants to train to awaken more tomoe, but Sasuke reveals that it doesn't work like that, only heightened emotions from extreme situations can awaken more tomoe. Sasuke proposes helping Sarada master her one tomoe Sharingan first. Knowing what Sarada struggled with during her last mission, he has her dodge a barrage of projectiles. She fails, but isn't disheartened by it, and asks to keep going. Konohamaru and Mugino investigate Victor's company, but are only shown more legitimate labs. Discussion gets more aggressive when they ask about the Hashirama Cell, but Konoha can't force the issue without escalating it into a diplomatic incident. Himawari misses her brother during dinner, and Hinata explains Boruto's determination for getting stronger. When Boruto asks for advice on his training, Kakashi refuses it, but instead tells him what Naruto learned when training wind nature transformation. Boruto feels frustrated, blaming himself for Mitsuki's injury, and envying how strong Kakashi was at his age. Kakashi points out the hardships he had to endure, and envies Boruto for growing up in an era of peace. He hands Boruto a lunchbox Himawari dropped for him, telling him he's not alone, which gives Boruto an idea. Sarada fails to dodge another barrage, and Sasuke tells her not to focus on all targets, and instead focus on the area of the attacks. Sarada also thinks back to Mitsuki's injury, and asks for another barrage. Boruto manages to add wind nature to his Rasengan with the aid of a shadow clone, and passes out from exhaustion. Sakura watches Sarada training. Victor's secretary reports having escorted Konohamaru and Mugino to the border, but in reality they have infiltrated the company to find the truth about Victor.
