Well, it's likely to be a very odd and non - canonical take on the Naruto universe. It might incorporate some elements of magic or strange experiments to explain the breast growth aspect, which is completely different from the normal Naruto plot.
Yes, there might be some Naruto fanfiction out there that involves such strange concepts, but it's not a very common or mainstream type within the Naruto fanfiction community. It often goes against the original spirit of the Naruto series which focuses more on ninja battles, friendships, and self - growth.
Well, a fanfiction could explore how Minato and Kushina's love for each other is reflected in their care for Naruto. Their strong bond as a couple helps them create a loving and stable environment for their baby.
Naruto himself is of course extremely popular. His journey of growth is what the fanfiction often focuses on. Another popular character is Sasuke. His complex relationship with Naruto and his own path of development make him a key figure in many fanfictions.
One interesting plotline could be a character in the Naruto universe suddenly starts to grow into a giantess due to a strange jutsu gone wrong. For example, Sakura might grow and have to deal with the chaos it causes in the village. She could accidentally step on buildings while trying to figure out how to reverse the growth.
Sasuke could be an interesting main character for this type of fanfiction. His brooding nature and powerful abilities would add an extra layer of complexity to the story if he were to experience giantess growth. He would have to deal with not only the physical changes but also his own pride and how it's affected by this new form.
Sasuke is also popular. In Naruto accelerated growth fanfiction, his relationship with Naruto often takes on new dimensions. With Naruto's growth, Sasuke might react in different ways, either being inspired to grow himself or feeling threatened. Their rivalry and friendship are key elements that fans enjoy exploring in these stories.
Perhaps Naruto and Ino are in the same art class in high school. Naruto is a bit of a wild artist, with big and bold ideas, while Ino is more refined in her approach. They initially clash over their different styles, but as the semester progresses, they find inspiration in each other. They collaborate on a big art project for the school exhibition, and through this experience, they not only create a beautiful piece of art but also a deep bond of friendship.
One interesting plotline could be the main character quickly mastering new jutsus at an accelerated rate. For example, Naruto might learn advanced nature transformations in a very short time, which would completely change the power dynamics in battles against enemies like Akatsuki. This would lead to him being able to protect the village in ways he couldn't before, and also gain more respect from the villagers who once shunned him.
