Story Idea:
I usually give out story ideas in the hope that someone will grab them and create something unique. This is another one and I feel very strongly about it so let's hope you all go for it.
Premise:
Crossover between Naruto and Eyeshield 21
Naruto finishes the war and works for a number of years as a hopeful candidate for the position of Rokudaime Hokage with the other 2 candidates being Shikamaru and Sasuke.
Scene change to him in the new world, de-aged to 16 (Same age as Sena, Karin, Monta, Suzuna, Huh Huh Bros etc.). Go with it and check the age dates on wiki.
I won't hinder the creativity,
I would recommend that you work with no chakra, strong, fast, 6'0 Naruto reflexes, and his height at the end of the manga can go to 6'2-6'3.
3000-6000 word chapters
Deimon devil bats Lineback in defense and 2nd runner, Ishimaru position in attack. Id also recommends him being a second QB with a favorite tactic being faking a run by sena, while the receiver runs that distracts everyone. Hiruma sneaking into past scrimmage but since he doesn't have the ball, no one stops him until he gains yards only to have Naruto QB a pass.
I think the games can be more intense with a higher emphasis on interaction with talking than just saying what happened.
Naruto moves on with his life so he doesn't bother telling people about his past. His new dream is to play NFL, be the best, and become crazy rich and successful while also helping his friends reach there. He also wants a family in the future.
He is also sleeping around with a lot of the female characters but there is only one serious love interest that builds slowly from before Naruto joins deimon as he is checking out the different schools with Teikoku Alexanders being one of them.
He meets her there and they become friends. Build it at your leisure but they start dating after he returns from the training camp in America preferably after giving it time to develop and grow.
You should continue the story past the manga since it has potential, Karin being his future wife taking an important role however you want.
This is me snowballing key ideas however it's your story do what you will. I plan on writing it myself but I love when multiple people take up challenges and do it in their own way.
I am willing to revel some plot:
I will follow a large part of the manga but after, Hiruma and naruto go to the same college. Naruto is a year younger than him but they are friends since Hiruma is a genies and naruto sneaky smart.
Also they plan on Naruto being in the NFL after the Manga is over since Hiruma believes Naruto is a once in a generation talent, better than Agon. He has pace (eventually surpassing Sena and Panther), height, Strength, insane stamina skill.
I intend for a particular Japanese investor to take over a stuggling almost failing NFL team and recruit select Japanese players and staff to bring their brand of football to the NFL. Of course, it has to be realistic (as realistic as it can get) as the NFL is on a whole new level. This part only starts after they graduate from college.
In any case, I hope others take an interest and give it a go.
Mail me if you decide to take on the challenge and, as Hiruma would say
"If you have balls, lets see you do it"
