Minato and Naruto started the fight. They were simply sparring in hand to hand combat. Kushina was cheering for both of them. But she cheered for Naruto more. At the same time Boruto was cheering for Minato. Himawari was staying in Kushina's hands. She said,
"Grandma, you look younger and prettier than mom. And your red hair is so cool."
Kushina blushed and said,
"You are the third person to compliment my hair. Well I wish my little princess had a hair like mine."
Himawari become curious and asked,
"Who were the first two people to compliment your hair Grandma?"
Kushina looked at Minato and Naruto. She said,
"It's your grandpa and your dad."
Himawari smiled and she hugged Kushina.
Minato was too tough to defeat so Naruto entered into the sage mode. Naruto gathered nature energy so quickly even Minato became amazed. Naruto started attacking Minato faster and stronger. Still he felt he's not getting anywhere.
Goku was cheering for both of them. He knew the outcome of the battle and still supported both of them.
The fight had gone too wild. Everyone watching around started to retreat to safe places. Naruto was trying to connect one punch on Minato but he didn't succeed. Minato was showing how quickly he can move without the teleportation ninjutsu. Naruto made a rasengan and tried to hit it on Minato.
Minato felt like he saw Jiraiya sensei in Naruto. Minato also made one rasengan in the same size that Naruto created. They both collided with it and Naruto's rasengan completely vanished even when he was in the sage mode. Minato avoided hitting his rasengan on Naruto, otherwise he would have lost his other arm.
Naruto became angry and he lost his control. He suddenly released the power of the kurama. Minato saw that and he powered down. He stood there like he's giving up. Naruto didn't wait he charged towards Minato and said,
"You told me not to let down your guard dad. And now look who's doing that."
Minato was smiling. Naruto became so close to Minato and that time Kakashi jumped in between them.
