One way is through shared adventures. For example, they could go on a mission together where they face a really tough enemy. This would make them rely on each other more and deepen their bond. Another way is if Naruto starts training Akamaru in some new skills. This would not only make Akamaru stronger but also show Naruto's care for him.
One possible fanfiction could be about Naruto and Hinata going on a mission with Akamaru. Maybe they encounter a powerful enemy and have to work together using their unique skills. Naruto with his shadow clones, Hinata with her Byakugan, and Akamaru with his enhanced senses. They could form an unbeatable team and learn more about each other in the process.
Perhaps in the fanfiction, there's a new threat to the village that requires special skills to defeat. Naruto's rasengan, Hinata's gentle fist, and Akamaru's ability to transform into different forms could be combined in unique ways. They might have to train together to master these new combined techniques. For example, Hinata could use her Byakugan to find the weak points of the enemy, Naruto could attack with the rasengan guided by Hinata, and Akamaru could provide a distraction or additional support.
One interesting Naruto and Akamaru fanfiction could be about Akamaru getting lost in the forest during a mission and Naruto using his shadow clones to search for him. They might encounter some rare and dangerous beasts along the way, but Naruto's determination and Akamaru's loyalty would shine through in the end.
In this fanfiction, perhaps Akamaru's 'in heat' state causes some chaos in the village. Naruto then uses his ninja skills to keep Akamaru in check and prevent him from causing too much trouble. He might also seek advice from Kakashi or other experienced ninjas on how to deal with it.
One great fem Naruto and Akamaru fanfic could be one where fem Naruto has a special bond with Akamaru. Maybe in this fanfic, they go on adventures together in the forest near Konoha. Akamaru could help fem Naruto sense danger or find hidden paths.
First, know the characters well. Naruto is brave, determined and a bit of a goofball, while Akamaru is loyal and has a strong bond with Kiba. Then, come up with an interesting plot. It could be a new adventure they go on together, or a problem they have to solve. For example, a mystery in the Hidden Leaf Village that only they can solve.
Well, it could be a really interesting story. Maybe it would explore a different side of Naruto if she was female. And Akamaru could be her loyal companion in some new adventures. The 'lemon' aspect might add some light - hearted or comical moments, like maybe they get into some silly situations while trying to get a lemon for a recipe or something.
There could be a fanfiction where Female Naruto meets Akamaru when he is just a puppy. She decides to train him in a different way than Kiba. This could lead to Akamaru having unique abilities that are a combination of Naruto's and Kiba's training styles. For example, Akamaru might be able to use some basic ninjutsu along with his natural Inuzuka clan skills.
To develop Naruto in this fanfiction, you could focus on his ability to adapt to the new situation with the female Akamaru - like character. He could learn new skills or ways of thinking from her. For the female character, show her evolution from a somewhat wild and instinct - driven being to someone who can make rational decisions. You can also develop her by exploring her relationships with other characters in the Naruto universe aside from Naruto. Maybe she has an interesting dynamic with Shikamaru or Sakura. Show how she changes and grows through these interactions.
