In a fanfiction about Naruto, the Gura Gura Fruit, and the Third Shinobi War, perhaps the Gura Gura Fruit is a new, mysterious element introduced into the war. Naruto, being the curious and adventurous ninja he is, might be the first to discover it. His friends and allies could be initially wary of this strange power, but as Naruto learns to control it, they see its potential in turning the tide of the war against powerful enemies such as Orochimaru or the Hidden Stone Village's forces.
One possible plot could be Naruto somehow obtaining the Gura Gura Fruit. He then has to learn to control its powers while still maintaining his own ninja skills. For example, he might accidentally cause earthquakes during battles at first, but as he masters it, he combines the fruit's power with his Rasengan, creating a super - powerful attack.
Romance is a very common theme. It often involves the reader character falling in love with 'ame' in different scenarios, like in a fantasy world or a modern - day setting.
Start with small interactions. For example, if the OC is a kind neighbor, they could offer Ame some home - baked cookies. This simple act can start a friendly connection. Then gradually introduce more complex situations like when Ame gets into trouble in his wolf form and the OC helps him out without asking too many questions at first.
In this fanfiction, Naruto with the Gura Gura Fruit might face a new type of antagonist. This antagonist could be someone who is also after the power of the fruit or someone who has a power that can counteract Naruto's new abilities. Naruto would have to figure out how to use the Gura Gura Fruit in combination with his existing ninja skills, like his shadow clones. He could create clones and then use the fruit's power through them to launch multiple attacks simultaneously, which would be a very interesting development in the story.
One possible plot could be that Kushina somehow gains the powers of the Gura Gura no Mi. She could use it to protect Naruto from various threats in the Naruto universe. Maybe she could create powerful shockwaves to fend off enemies like the Akatsuki. Naruto, seeing his mother's new power, would be inspired to train harder and learn how to combine his own jutsu with the power of the Gura Gura no Mi.
Some ina x ame fanfics might focus on a fantasy world where they have special powers. For example, they could be part of a magical guild and have to use their powers in combination to defeat a powerful enemy. This type of fanfic can explore their relationship in a more high - stakes and exciting context.
Naruto could use the Gura Gura Fruit to create huge tidal waves in battles near water sources. This would be a great advantage against enemies not used to fighting in water. For example, if facing the Sand Village ninjas, he could flood the desert battlefield, disrupting their attacks and movements.
Naruto would become more powerful, and this might make him a bit more cautious. He's used to his regular ninja abilities, but the gura gura fruit's power is on a different level. He might be more hesitant in battles at first, not wanting to accidentally cause too much destruction with the fruit's earthquake - causing ability.
