In a more comical fanfiction, Naruto might accidentally control Anko's eating habits. Let's say he uses a new jutsu that backfires and instead of affecting an enemy, it affects Anko. So, every time Naruto thinks about a certain food, Anko starts craving it and can't resist. This would lead to some really funny situations as Anko tries to fight against this strange control while Naruto is desperately trying to figure out how to undo the jutsu.
One idea could be that Naruto gains some new power or jutsu that allows him to control Anko's actions in a non - malicious way. Maybe it's a form of genjutsu that he accidentally uses on her during a training session, and then has to figure out how to reverse it.
One possibility is that Anko is poisoned during a mission. Naruto, having learned some medical ninjutsu from Tsunade, uses his skills to find an antidote and save her. He might have to search far and wide, facing various challenges along the way.
Well, they could start a new life in a far - off land. Maybe Naruto would learn some new techniques from the local ninjas there. And Anko could use her experience to help them build a small community.
In this fanfiction, they could become really good friends. Anko might help Naruto get over some of his insecurities. Maybe they'd have some adventures together in the village, like exploring some old, forgotten parts of Konoha. And Naruto could also introduce Anko to his other friends, like Shikamaru and Choji.
One possibility is that Naruto would go into self - exile and train on his own. He might find new powers and allies outside the Hidden Leaf Village. With Anko, she could be conflicted. She might secretly help Naruto, believing that his banishment was unjust. This could lead to a whole new adventure where Naruto has to prove himself worthy without the support of his home village.
Well, in such a fanfiction, Naruto might use his unpredictable nature to bluff in poker. Kurenai, with her calm and collected demeanor, could be really good at reading opponents. And Anko, being a bit wild, might make some risky moves. Maybe they're playing poker as a way to relax between missions or it could be part of a training exercise where the winner gets a special prize.
Naruto could have a different personality. Since Kurenai is calm and Anko is bold, he might be a more balanced character. He could be more confident in social situations, having learned from both of them. For instance, he wouldn't be as much of an outcast as in the original story.
Maybe Anko would be shocked to find Naruto drunk. She could scold him for acting irresponsibly as a ninja. Or she might try to help him sober up and figure out why he got drunk in the first place.
One possibility is that Naruto's positive attitude rubs off on Anko and Kurenai. Anko, who has had a tough past, might start to open up more because of Naruto. And Kurenai, who is usually so reserved, could become more adventurous in love. Naruto might be the catalyst for their growth in the relationship.
In some fanfiction concepts, Naruto and Sakura might control the dead through powerful jutsu. Maybe they discover an ancient forbidden technique. For example, they could find a scroll that teaches them how to manipulate the souls of the dead. This could be a result of their continuous exploration and growth in the ninja world.
