One idea could be a fanfic where a young ninja discovers a unique way to combine lightning jutsu with other elements like water, creating a new and powerful technique. This could lead to him being sought after by different clans for his knowledge.
Perhaps in the fanfiction, Naruto perfects the Sexy Jutsu to the point where it can be used for espionage. He could transform into a seductive character and infiltrate enemy strongholds, gathering valuable information without being detected. This would add a new dimension to his ninja skills.
He might become more confident. As he perfects the Sexy Jutsu, he has to overcome his initial shyness or hesitation. This new - found confidence could spill over into other aspects of his life, like his battles and his interactions with others.
A third idea for a Naruto poison jutsu fanfic could be a story set in a different era of the Naruto universe. In this time, poison jutsu is a highly respected and feared art. A young ninja, inspired by tales of Naruto, tries to master poison jutsu. However, they face many challenges, including a corrupt master who wants to use the ninja's skills for evil. The young ninja must then decide whether to follow the master or break away and use their skills for the greater good.
A fanfic could also explore Naruto using the Smoke Jutsu for a rescue mission. Suppose some of his friends are trapped in a building surrounded by enemies. Naruto uses the Smoke Jutsu to cover the area. The smoke is so thick that the enemies can't see. Then he sneaks into the building, rescues his friends, and they all escape under the cover of the remaining smoke.
A possible fanfiction could be one where the Kyuubi is trapped in a genjutsu created by an enemy, and Naruto uses his Sexy Jutsu to break the genjutsu. The Kyuubi, being freed, then forms a sort of pact with Naruto that involves teaching him some of its more powerful techniques in return for Naruto using his Sexy Jutsu to disrupt any future genjutsu attacks. This would be a story full of action, humor, and a unique bond between Naruto and the Kyuubi.
Well, it could be that the Sexy Jutsu has some sort of psychological effect on the Third Hokage. Maybe it reminds him of someone or something from his past that makes him hesitate. And in that moment of hesitation, Naruto is able to use the distraction to his advantage and defeat the Third Hokage. Also, Naruto might be able to use the jutsu in combination with other moves in the fanfiction. For instance, while the Third Hokage is distracted by the Sexy Jutsu, Naruto quickly follows up with a Rasengan.
A 'naruto kawaii no jutsu fanfic' is likely a fan - made story related to Naruto's 'Kawaii no Jutsu'. It might focus on how this jutsu affects different characters in the Naruto universe. Maybe it shows some comical situations where Naruto uses the jutsu in unexpected ways or how it changes the relationships between characters.
One common theme is the discovery of new sealing jutsu. Writers often create new and powerful sealing techniques for their characters to find or develop. Another theme is the power struggle related to sealing jutsu. Since they can be used to seal away great power or even demons, there's often a fight over who controls them.
First, do research on all the existing lightning jutsu in Naruto. This will give you a solid base for your fanfic. Then, create unique characters with their own relationships to lightning jutsu. For example, a character who fears lightning but has to learn lightning jutsu to protect their loved ones.
