Kakashi would probably raise an eyebrow and make a dry joke about Naruto's new look. But he would also be ready to help if Naruto was in some sort of trouble because of it. As for Lee, he might see it as a new form of training or a way to build character. He would encourage Naruto to embrace his crossdress toad look and use it to his advantage in some way, like scaring opponents in battle. Naruto's other friends like Ino would probably gossip about it at first but then get used to it over time.
Often, in these early fanfics, Naruto might show a quicker mastery of toad - related jutsu compared to the original series. His connection with the toads could be more profound from the start.
One interesting 'Naruto Toad Sage Fanfic' could be about Naruto exploring new toad sage techniques that were not shown in the original series. For example, he might discover a way to combine his Rasengan with toad sage chakra in a more powerful and unique way.
One possible reason could be that Naruto wants to develop his own unique ninja way without relying on the traditional toad contract. He might feel that it would limit his growth in a sense.
Obviously, Naruto himself is the most important character as it's about his journey to become a toad sage. The toad sages like Fukasaku and Shima play crucial roles too. They are the ones who guide Naruto and teach him the ways of the toad sage.
Well, in many such fanfictions, one key event is Naruto's initial encounter with the toads in their realm. He might face challenges to prove himself worthy of their teachings. Another event could be his intense training sessions with the toad sages, learning new jutsu and wisdom.
I recommend "The Hakone Serpent of the Wilderness." This novel was about a female protagonist with a heavenly eye who was kidnapped by an unscrupulous Taoist to become the disciple of the big liar, Shen Nong. Among them, the Hakone Serpent was one of the most important villains and was known as one of the Nine Beasts. In the novel, it would be summoned to fight against the main character and the others. I hope you like this fairy's recommendation. Muah ~😗
Toad Cave meant Moon Palace. Toad Cave was a Chinese term, its pronunciation was chánkū, meaning Toad Palace. In ancient literature, the toad cave was often used as a metaphor for the moon. For example, Su Shi, a poet of the Song Dynasty, wrote in his poem,"On August 17, Tianzhu Mountain sent osmanthus flowers to distribute elements":"On the night before the fall of the peak, the toad cave branch remembers the past years." The toad cave in this poem referred to the moon. Therefore, the name Toad Cave meant Moon Palace, which was used to refer to the moon.
The toad palace meant the moon palace or the palace of the moon. The toad palace usually referred to the legendary Guanghan Palace where Chang'e lived. Every time night fell, the bright moonlight sprinkled over the earth, and people would have countless thoughts and fantasies. The toad palace could also refer to the palace in the moon.
Perhaps Naruto has had some negative experiences or premonitions related to the toads. Maybe he saw something in a dream or heard a story that made him hesitant about entering into the contract. Another aspect could be that he wants to break away from the traditional paths of the ninja in his village and forging a new way without the toad contract is part of that.
