"Tomoe!?"
Shinji furrowed his brow and turned to look at the mirror on one side of the laboratory.
In the mirror, three regularly arranged black tomoe had indeed appeared in each of his pale purple Rinnegan.
"This..."
Shinji was stunned.
There were actually many different forms of the Rinnegan. Shinji knew that.
For example, his own, Madara Uchiha's, and Karin's Rinnegan all had pale purple irises with spiral patterns.
Otsutsuki Urashiki of the Otsutsuki Clan, on the other hand, possessed a Rinnegan that could switch between three forms: the Byakugan, the Golden Rinnegan, and the blue Rinnegan.
Differences in color were just one way to distinguish the forms of the Rinnegan.
Another distinguishing feature was the tomoe on the Rinnegan's spiral pattern. That was where the name "Tomoe Rinnegan" came from.
Shinji clearly remembered that in the original timeline, when Madara Uchiha absorbed the Ten-Tails and activated Infinite Tsukuyomi, nine tomoe had appeared on the blood-red Rinnegan in his forehead.
And during the Fourth Shinobi World War in the original timeline, after Sasuke received the Yin Power bestowed by the Sage of Six Paths, the Eternal Mangekyo Sharingan in his left eye successfully awakened into a Rinnegan. That Rinnegan also had six distinct tomoe!
Nameless leaned closer and stared at the mirror with Shinji. "Oh, three tomoe on each side, just like the Sharingan!"
"Mm!"
Shinji nodded slightly.
Because the Tomoe Rinnegan was so rare, very little information about it was available. After all, aside from Sasuke Uchiha and Madara Uchiha, only the Otsutsuki had ever possessed this kind of Rinnegan, so Shinji knew very little about it.
But one thing was certain: the tomoe on the spiral pattern should represent special Dojutsu.
They could be understood simply as the Dojutsu of the Sharingan, or as a special kind of
