The technique was also used, without success, by Mitate to attempt to reverse Menma's amnesia. Menma's memories eventually returned without the aid of the Time Reversal Technique after the Konoha hospital was struck by lightning. The Purizumu clan has a developed use of this Genjutsu called Prismatic Illusion. By centering the chakra through the Gensanryoukyou prism, the jutsu has an improved effect and requires a lesser amount of chakra.
