There was no need to ask anything else. Just this alone was enough for Shinji to determine that the completely damaged Mangekyō Sharingan in Karin's eye sockets had truly been fully restored.
"I have to say, your constitution is even more special than I imagined!"
Shinji let out a sigh of admiration.
He had done his best to account for Karin's potential, but the results she had delivered still surprised and delighted him!
Karin hurriedly asked, "My lord, I haven't disappointed you, have I?"
"You did wonderfully!" After praising her, Shinji's smile faded, and he asked seriously, "Since you awakened these Mangekyō Sharingan through your own ability, you should have mastered the Dojutsu they contain as well, right?"
Karin nodded vigorously. "Mm-hmm. The left eye contains a Dojutsu called 'Amaterasu,' while the right eye contains one called 'Kagutsuchi.' The left eye's 'Amaterasu' can unleash black flames, and the right eye's 'Kagutsuchi' can shape them."
Shinji froze halfway through her explanation, a thought bubbling up in his mind. Aren't those the exact same two Dojutsu as Sasuke's Mangekyō Sharingan?
Shinji was familiar with both 'Amaterasu' and 'Kagutsuchi.'
There was no need to explain 'Amaterasu.'
'Kagutsuchi' was the Dojutsu contained in Sasuke's right eye after he awakened the Mangekyō Sharingan in the original timeline!
"How could they be exactly the same?"
Shinji was puzzled.
But then he thought about it: after awakening the Mangekyō Sharingan, Fugaku Uchiha, Itachi Uchiha, and Sasuke Uchiha had all awakened the Dojutsu 'Amaterasu.'
That showed it was entirely possible for different Mangekyō Sharingan to awaken the same Dojutsu.
*Could the completely damaged Mangekyō Sharingan Karin restored have belonged to an ancestor of Sasuke's line? Right, I remember that during the Fourth Shinobi World War, the Second didn't seem surprised at all when he saw Sasuke use 'Kagutsuchi.'
