"Of course we're gonna start with training to fight."
Kai said while sprinting straight to where Naruto was before punching him in the stomach with only enough power to sting a little bit of pain.
After giving Naruto a little punch as an opening ceremony, Kai makes some distance while naruto complaining about the little pain that he felt.
"Don't exaggerate Naruto, you need to fight back or you're gonna go back to the old way of learning, reading it from a book."
The moment he mentioned about reading it from the book again to Naruto, Kai saw Naruto who seemed to like having an energy boost stop being too overacting and started sprinting toward him while shouting his hardest.
When Naruto was closing toward him, Kai prepared himself to block the punch that was coming towards his stomach before he grabbed the arms and pulled it to make Naruto fall to the ground.
He was disappointed but at the same time quite touched by Naruto who seems to have no intentions of actually throwing punches toward him.
"Keep your concentration on what you want to do and don't hesitate Naruto"
"You can try to hit me with the punch."
After seeing Naruto getting up from the ground and started charging towards him and tried to punch him again but still with hesitation in his eyes even he already mentioned about the book that Naruto really doesn't quite fond in it.
The moment Naruto punch wanted to land on him it Intentionally missed the target, Kai thought it was not gonna be work if this kept happening and decided to fix it first.
Using his legs Kai sweeps it towards Naruto who still in his range and sends him flying a little bit.
Walking towards Naruto Kai over a hand to Naruto who was on the ground to help him get up before walking towards one of the trees in the vicinity.
"Look here Naruto."
Sprinting toward the tree, Kai jumps and does his flying kick technique with full power and increases weight on his legs to maximize the damage output, trying to impress Naruto with it.
"Dynamic Entry."
Hitting the tree trunk that was quite decent size Kai was able to make it fall to the ground.
"Woahh…, Kai Onii-san you're so strong."
Naruto looked all over the place where the aftermath of the tree that was falling to the ground curiously while having an impressive expression on his face.
"Of course your Onii-san was really impressive."
Kai spoke with a proud tone in his voice while raising his chest and trying to hide the fact that he was holding a little pain in his legs.
"Now you already see the impressiveness of your Onii-san, so you don't have to hesitate anymore Naruto."
"You can fight with me with all of your might naruto."
"Alright Kai Onii-san."
After that Naruto finally was able to fight him with no hesitation anymore and they were training until the afternoon came where he called it quits because it was gonna be uncomfortable when night came especially they were in the winter season.
Moreover, his mother was gonna be worried because he's been outside since morning.
But as expected from uzumaki lineage, Naruto can keep following the pace of their training without really having any difficulty in the stamina section even if it is just his first time doing his training.
"Good job Naruto, come we gonna eat ichiraku ramen. I'm gonna treat you until you are satisfied as a celebration for the first time you started your combat training."
"Yay…, thank you Kai Onii-san"
After that both of them start walking toward where the ichiraku ramen was, along the way he ask Naruto about his daily stuff that happened on this week and other light conversation before they finally arrived in front of the shop.
"Excuse me." x2
"Ohh…, Kai.., Naruto…, what I can help you with"
"Teuchi Oji-san I want extra large miso pork ramen."
Sitting on the chair Kai also order his own food, tonkatsu ramen with half boiled egg that his favorite type when he was visiting ichiraku ramen.
"One extra large miso pork ramen and tonkatsu ramen with half boiled egg coming right up in a minute."
After a while the food finally arrived and they start eating the food where Naruto order 2 more bowl after finishing the first one.
After paying for the meal Kai bring back Naruto to the front of his apartment and said goodbye to Naruto before he starts heading towards his home before night was fall.
