This story takes place after Naruto died at the age of 117. Instead of the world becoming advanced in technology they realized their powers were stronger than that. They regressed after Boruto back into a world similar to naruto, but definitely not the same world. Warning - Swearing/Violence
Ray: Are we just going to make it a thing to come to the training ground after class?
Renjiro: If you really want to.
They both make the clone hand seal.
Ray/Ren: SHADOW CLONE JUTSU!
They spawn 10 shadow clones each. Then they all jump in and battle each other for hours. Then they put up the tiger hand seal.
Ray/Ren: FIRE STYLE: FIREBALL JUTSU!
They both send fireballs at each other. They dodge it and fall to the ground. Since they don't have a lot of chakra left. Then they just lay on the ground.
Renjiro: Ray is it okay if I sleep over your house today?
Ray: Sure Ren, sure.
All their clones disappear.

Ray falls asleep, and Renjiro is still up. Ray's mother is doing paperwork in the dining room, and Renjiro walks in.
Renjiro: I will help you wage a war on my father.
Ray's Mother: Now why would I believe you?
Renjiro: Because the only reason I wouldn't help you before is that my mother wasn't killed by him.
Ray's Mother: Would you even be useful though? You're young.
Renjiro: Is Ray useless?
Ray's Mother: He's our wildcard.
Renjiro: Now you have two.
Ray's Mother: I like you.
Renjiro goes back to bed

Months later of training, and going to the academy. It is time for the midterms.
Midori: I hope you have all practiced real hard. The first thing we are doing is wall climbing.
All the students take their turns, and complete the wall.
Midori: Perfect. Now is time for the test.
They all take the test, and everybody passed. Even though one student almost didn't.
Midori: That was a close one, but you all passed. Now time for the jutsu test. Hopefully, you all know at least 1 ninjutsu.
Everyone goes up, and does the shadow clones jutsu. They all spawn 3 clones.
Midori: GREAT! YOU ALL PASSED THE MIDTERMS! SO TOMORROW WE WILL START THE HARD STUFF!
