Kamui vs. Timehold (Monthly Vote Request!)

Hearing Obito's casual mockery, Shinichi's expression immediately darkened. Even the Mangekyō Sharingan in his eye sockets seemed to dim considerably.

Narrowing his eyes slightly, Shinichi struggled to suppress the rage in his heart.

Just as Obito had said, his eyesight had indeed deteriorated severely. After using "Timehold" twice in succession just now, he had consumed a great deal of his Mangekyō Sharingan's ocular power, and now the things before his eyes were beginning to blur into faint double images.

In fact, after joining Akatsuki, Shinichi had rarely used his Mangekyō Sharingan.

It was only when he had first awakened the Mangekyō Sharingan and knew little about it that he had acted too rashly. He had stormed into the Root base alone, intending to take revenge on Danzo. After finding nothing, he had fought his way out of the village, recklessly expending his ocular power in battle until he encountered Hyuga Kagami. Kagami had consecutively broken through both his Susanoo and Heaven Guard, the two Mangekyō Sharingan techniques, leaving him badly weakened.

It could be said that in those brief few days, he had squandered seventy or eighty percent of his Mangekyō Sharingan's ocular power.

This was somewhat similar to Sasuke's situation in the original timeline.

After awakening his Mangekyō Sharingan, Sasuke had actually only gone through three major battles: Taka's capture of the Eight-Tails, his rampage at the Five Kage Summit, and his killing of Danzo.

Yet within those short few months, Sasuke, who possessed Indra Ōtsutsuki's chakra, suffered a severe decline in vision. His newly awakened Mangekyō Sharingan had nearly gone blind, forcing him to fuse the Eternal Mangekyō Sharingan.

This showed that as long as someone pushed it hard enough, a pair of Mangekyō Sharingan
