Sure. Some fanfic authors might be interested in exploring their friendship or a more platonic bond. They could write stories where Naruto and Anko work together to solve a mystery within the Hidden Leaf Village. This kind of fanfic would not involve any adult themes but rather focus on the unique personalities and skills of the two characters.
There probably is. Fanfics can take various forms. It could be a story where Naruto, in his younger days (shota), has an encounter with Anko that changes his perspective on something important in the ninja world. Maybe Anko shares some of her own experiences with Naruto, which helps him grow as a ninja, all without any adult - related content.
Yes, there are likely non - adult fanfics out there. Many fanfic writers focus on creating stories that explore the relationships, adventures, and character development of Naruto and Anko in a more innocent and plot - driven way. For example, they might write about team - ups for missions, or how Anko could act as a mentor to Naruto in certain aspects of ninja training.
