It could be a fanfiction that focuses on a character in Naruto experiencing withdrawal symptoms related to ramen. Maybe Naruto himself is deprived of his beloved ramen for some reason and the story explores how he copes.
Perhaps a ninja who has a grudge against Naruto because he once ate all the ramen at a festival, leaving none for the ninja. So this ninja decides to target Ichiraku Ramen and tries to put a curse on the ramen that would make anyone who eats it sick. Naruto has to figure out how to break the curse and stop the ninja.
Naruto is most likely to be the main character since it's about his ramen withdrawal. But his friends like Sakura and Kakashi might also be important as they could be the ones trying to help him or dealing with his mood swings due to the withdrawal.
The 'Ramen Girl' is purely fictional. It was crafted by the imagination of the writers and filmmakers to present an engaging narrative, not based on real events or people.
The comic book on cooking ramen might first introduce the necessary tools and ingredients. Then, it could visually guide you through each stage of the cooking, such as the right temperature for the water and the order of adding the components for the best flavor.
One popular genre is the 'What - if' genre. For example, what if Naruto had a different upbringing or if certain characters didn't die. Another common one is the 'Self - Insert' genre where the author inserts themselves or an original character into the Naruto universe. And there's also the 'Romance' genre, which focuses on the relationships between the characters in Naruto, like Naruto and Hinata's relationship, but with different takes and story developments.
Well, perhaps in this fanfiction, Naruto left because he felt unappreciated in the Leaf. But then the Leaf discovers some secrets or powers that are tied to Naruto. They start to see all the good he has done in the past and make a big effort to bring him back. They might hold a big ceremony to welcome him and show how much they truly value him now.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). There are a large number of Naruto fanfictions on these platforms, covering various themes and storylines.
Obviously Naruto would be one of the main characters as the story is about getting him back. Sakura could also be a main character. She might be one of the ones leading the effort to bring Naruto back, using her medical skills and her friendship with Naruto as reasons to convince him.
