Ever since Uchiha Chiri uttered that astonishing theory—that if someone could perfectly master both of their own Mangekyou Sharingan Jutsu, successfully fuse them together, undergo a series of wondrous and mysterious transformations, and finally apply this fused jutsu power back onto themselves, it might be possible to give birth to a unique and powerful ability akin to a legendary Kekkei Genkai.
To Uchiha Chi, this perspective flashed across his mind like lightning through the night sky, instantly igniting a raging fire of ambition deep within his heart. He became convinced that once formed, this special Kekkei Genkai would perfectly fit the Mangekyou bloodline, further stimulating his potential and vastly increasing his strength to reach the level of Uchiha Madara and Senju Hashirama.
It would even make his own Mangekyou Sharingan resemble the Eternal Mangekyou Sharingan, where not only would his Pupillary Power increase dramatically, but the drawbacks of the Mangekyou—namely unrecoverable vision loss and eventual blindness—would be completely eliminated.
