Anime Naruto, Uchiha has the blood inheritance limit of writing wheel eyes, writing wheel eyes in addition to having the ability to copy, but also has the potential to evolve, in anime, writing wheel eyes can evolve into kaleidoscope writing wheel eyes, but if you want to evolve into kaleidoscope writing wheel eyes, one of the things you must experience is the death of the people you cherish around you.
In the anime, Uchiha Sasuke in order to get revenge on Uchiha Ferret, bent on getting power, and this time the Great Snake Maru threw an olive branch to Sasuke, Sasuke also chose to run to the Great Snake Maru in order to get stronger power, Naruto who learned the news chose to chase Sasuke, just in the Valley of the End, Naruto and Sasuke launched their first official duel, the location is in the Valley of the End.
In fact, when it comes to Sasuke's writing wheel eye, Sasuke has experienced a very great pain from the time of opening the eye, the general writing wheel eye does not need to witness the death of a loved one, but Sasuke directly witnessed the death of the entire family, which is undoubtedly a very huge blow to the young Sasuke, but even so, he did not directly open the kaleidoscope, probably because he was too young.
Later, during the battle between Sasuke and Uchiha Ferret, Uchiha Ferret died after helping Sasuke get rid of the Chakra of the Great Snake Pill in his body, and after that, Uchiha took the earth to tell Sasuke the secret of Uchiha Mustela, and after learning of his brother's pain, Uchiha Sasuke opened the kaleidoscope writing wheel eye, and Sasuke's strength also got a qualitative leap at this time.
So the question is, since the prerequisite for opening the Kaleidoscope Writing Wheel Eye is to witness the death of the cherished person, then in naruto and Sasuke's first Battle of the Valley of The End, if Sasuke kills Naruto with his own hands, will Sasuke be able to open the Kaleidoscope Writing Wheel Eye? In the early days of the anime, was Naruto really that important to Sasuke? If it could be turned on, why didn't Sasuke do that?
In fact, for Sasuke, he had already regarded Naruto as his family, the two people had similar childhoods, but Naruto was a little stronger than Sasuke, that is, Naruto had never had the love of his parents since he was a child, and Sasuke had lost this love under the premise of having the love of his parents, compared to that, although Naruto was more pitiful, Sasuke was undoubtedly more sad.
Before joining the seventh class, Sasuke had already paid attention to Naruto, and Naruto also paid attention to Sasuke, but the two were still children at the time, and after joining the seventh class, the friendship between the two people soared, and in the final battle between the two, Sasuke and Naruto also confided in each other, in fact, they had long become each other's most important people.
The first time Sasuke defeated Naruto in the Valley of The End and left, Sasuke had already said that he could actually open the kaleidoscope, as long as he killed Naruto, Sasuke could get this power, but Sasuke did not do this, although the master said that he wanted to get the power in his own way, but he still knew very well that he could not attack Naruto.
So if Sasuke had killed Naruto directly in the battle in the Valley of the End, he would have been able to open the kaleidoscope writing wheel, but for Sasuke, Naruto was also the only friend in his life, so if he did kill Naruto, he would really become a loner, and maybe this was also indara and Asura's arrangement in the underworld.
In your opinion, if Sasuke had killed Naruto at that time, could he open the kaleidoscope?
