Next day in the classroom all kid who passed the exam were present. Today was the day they will be divided into team and paired with jonin senseis. Everyone was shocked to to see Naruto in the room with a ninja headband. But they were too pre occupied on them selfs to care about it.
After some time the room was almost empty. Only Kizo, Naruto, Sasuke, and Sakura were left. Then a jonin came in and took Sakura as well. Almost an hour later Naruto and kizo was busy taking with each other and Sasuke was ignoring their existence. Then the door opened and Kakashi walk in.
"Hello everyone i am Kakashi hatake. I will be your jonin instructor. How about you introduce yourself and talk about you likes this likes and dreams." Kakashi said.
Naruto was the first to talk" I am Naruto uzumaki. I love ramen. I hate the three minutes wait of ramen and my dream is to be the Hokage."
Then Kizo said " I am Kizo Torihino. I love spending time with my friends. I hate feeling weak and my dream is to have enough strength to protect all my friends and maybe open a restaurant one day. "
Then Sasuke said, " I am Sasuke Uchiha. I don't like anything. I dislike a lot of things. As for my dream I don't have a dream for i will make it a reality. I will kill a certain someone and restore the Uchiha clan. "
Their time as genin quickly passed. Originally team 7 had Sakura not Kizo. But the existence of Kizo changed it. Sakura was put on team 7 because of Naruto. Naruto liked Sakura, so Hiruzen to make Naruto more attached to the village put her in his team. But now because of Kizo Naruto didn't care about Sakura as much. His closest person now was Kizo. Because of that Kizo was now on his team.
In their past few months they completed a lot miniscule missions. But was the their fight against Zabuza of the mist. In that mission they finally learned what it meant be ninja. Kizo wasn't that strong at that time. Well it was because of Kakashi. Kakashi did not teache him anything special. And unlike Naruto and Sasuke he did not have any cheat abilitys yet. But you can count his chakra control as a cheat. He had near perfect chakra control. He could walk on trees and water in his first try. Plus his chakra reserve was almost near a mid chunin level. All of this really surprised Kakashi. With kizo's high IQ, EQ and everything combined Kakashi believed that Kizo had the potential to be a kage level ninja in the future.
So after that Kakashi teached many ninjutsu to Kizo. When tested his chakra nature affinities Kakashi found out the he had very high affinities for all five chakra natures. Which once again shocked Kakashi. He now believed that Kizo could became a ninja at the same level as hiruzen in the future.
