Perhaps they encounter some difficulties at first. The frogs' training methods could be very different from what they are used to. But as they adapt, they start to show significant improvement. Naruto might gain better control over his Nine - Tails chakra with the frogs' guidance, and Sakura could enhance her medical ninjutsu by learning about the frogs' natural healing abilities.
In the fanfic, they might learn new jutsu from the frogs. The frogs could teach them unique combat skills or ways to better control their chakra.
They might learn new jutsu from each other. Naruto could show Tenten some of his unique Rasengan variations, and Tenten might teach Naruto how to better handle different types of weapons.
They could become stronger. Naruto might gain new forms of his jutsu, and Sakura could become more confident in her abilities.
Perhaps in this fanfic, the cave is a place filled with mystery. Naruto and Sakura enter it following a strange chakra signal. Once inside, they encounter strange creatures. Naruto would jump into action first, but Sakura would be right behind him, ready to support him with her strength and intelligence. They would learn more about the secrets of the ninja world as they explore the cave.
In this fanfic, they could be suffering from different levels of hangovers. Naruto's hangover might be more physical, with a pounding headache and nausea. Sakura's could be more mental, as she's worried about how she behaved while drunk. Sasuke might be in denial about his hangover at first, but then it hits him hard. Karin could be using her knowledge of herbs to try and make a remedy for them all. There could also be some flashbacks to the night before, showing snippets of their drunken conversations and actions. These flashbacks could reveal some hidden feelings or secrets among the characters, adding more depth to the story.
Well, they might have a deep conversation. Naruto could open up about his dreams for the future of Konoha and Sakura could share her medical ninja goals. They might also get into a friendly sparring session as a form of entertainment during the date.
It could go in a different direction too. Naruto might reject Sakura's confession. He could still see her as a dear friend, but not in a romantic way. This would create a lot of tension between them, and Sakura would have to deal with the heartbreak. Meanwhile, Naruto would have to figure out how to keep their friendship intact despite the awkward situation.
In this kind of fanfic, perhaps there would be some unexpected guests. Maybe some old enemies who have now turned friends come to wish them well. The wedding ceremony itself could be a blend of traditional ninja elements and more normal wedding stuff. Naruto could wear a special version of his Hokage robes for the occasion. Sakura would have her hair done up all fancy. And the exchange of vows would be really emotional, with Naruto promising to always protect Sakura and Sakura vowing to always be by Naruto's side through all his Hokage duties.
One possible scenario could be that without Sakura, Naruto might become more reckless in his pursuit of protecting the village. He has always had Sakura as a support, and her loss could make him overcompensate. For example, he might take on more dangerous missions alone, believing that he has to be the sole protector now.
Maybe he has to find an alternative way to get to school. He could try to use magic to create a makeshift transportation or ask for help from his friends' families who might be passing by.
If Naruto confronts Yami in a fanfic, it could be a very intense encounter. Naruto would bring his vast array of jutsu, from shadow clones to his Sage Mode. Yami, on the other hand, would have his own set of skills. It could be a long - drawn - out battle where Naruto has to constantly adapt. For example, if Yami can manipulate darkness, Naruto might use his own chakra to create light - based attacks to counter. Also, Naruto's determination and never - give - up attitude would be put to the test as he tries to overcome Yami's challenges.
