1. Kaleidoscope sharingan is an evolved version of sharingan, not sharingan in its natural state. Single hook jade, double hook jade and three hook jade are all shared in the natural state. Single-hook jade is in an open state, and gradually accumulating experience will turn its strength into three-hook jade. Kaleidoscope is a higher level. Open the kaleidoscope. sharingan is too heavy for himself and will gradually become blind. If it is not necessary, it will not open the kaleidoscope casually.

2. Kaleidoscope becomes eternal kaleidoscope: Kaleidoscope becomes eternal, and only lineal blood relatives, such as father and son, can realize the fusion of eyes and create eternal kaleidoscope. It should be sharingan, who is not far from the two. It is estimated that there is no need to open a kaleidoscope (ferrets and Sasuke didn't have a kaleidoscope in wartime, but Banzai's younger brother did). When Jiraiya first saw sharingan in Nagato, he was also surprised that someone had it. The eye of the eye of the sky should be the immortal sharingan (refer to the evolution of the eye of the eye of the sky). The original question you asked was not introduced in detail, nor did I mention it.

3. sharingan finally evolved the rim of the eye, but its function seems different. When Nagato used the eye rims, he didn't show all the stunts of Saringen, but the spots also made the eye rims, which can also be used by people who need to stay. I think the rim of the eye should also have sharingan's ability. In the cartoon, it is said that using Xie Yi Nagi Saringen will make you blind, but this is just an ordinary Saringen. Without the fairy sharingan, I don't know what the eye circles are like. I'm not sure about that. See if the back spot can be used, and what will happen if it is used ~
