Just as Shisui was preparing to make another move, he suddenly sensed a familiar burst of ocular power and chakra erupt from within Nagato's body.
"What is that?!"
Enhanced by the vision of his Eternal Mangekyō Sharingan, Shisui could clearly see the complex, mysterious Mangekyō pattern in Nagato's left eye—the Kamui Sharingan that had originally belonged to Obito Uchiha—beginning to change.
"Could it be..."
A bad premonition arose in Shisui's mind.
Sure enough, after undergoing a complex transformation, the Mangekyō pattern in Nagato's left eye formed a new design, becoming even stranger and more mysterious.
"Is this... a new eye?"
Nagato raised a hand and touched his left eye, feeling an endless stream of ocular power pouring from it. It was a stronger, deeper power.
Sensing the changes in Nagato's left eye, Shisui, having gone through it himself, clearly understood that Nagato's left eye had evolved into an Eternal Mangekyō Sharingan.
"Dojutsu: Kamui."
The instant Nagato unleashed his Mangekyō dojutsu, Shisui sensed a deadly crisis. A force of space that had appeared from nowhere acted upon his body in an instant.
The sudden mortal danger stimulated Shisui's nerves.
"Body Flicker Technique."
Shisui instinctively used the Body Flicker Technique and vanished from where he stood. As Shisui's signature skill, the Body Flicker Technique had long become an unconscious bodily instinct; the moment the thought arose, he had already activated it.
After Shisui vanished, spatial distortion appeared where he had originally stood. It was the result of Kamui's spatial power taking effect.
Kamui was the unique Mangekyō Sharingan dojutsu of Obito Uchiha in the original story.
Kamui was an extremely advanced space-time ninjutsu. Its fundamental ability was to transfer any object back and forth between reality and a different dimension. Since Kakashi Hatake had transplanted Obito's left Sharingan, Kakashi could use Kamui
