Inside the office.
Naruto could sense Great Sasuke sparring with Little Sasuke.
The commotion the two of them were causing was far from small.
However, the plaza was protected by a special barrier, making it difficult for anyone outside to sense what was happening within.
Although Great Sasuke had been brought in to teach Little Sasuke, there was not really much left for him to teach.
Kakashi had taught him Lightning Release and swordsmanship over the years, while Madara Uchiha had taught him Fire Release. By now, both had reached a certain limit.
On top of that, the Seven Tails implanted in him several years ago had solved his Chakra issues.
Little Sasuke's true bottleneck now lay in his Sharingan.
It had been nearly six years since his eyes evolved into the Three-Tomoe Sharingan.
Yet even now, there was not the slightest sign of them evolving into the Mangekyō Sharingan.
Uchiha Itachi's pair of Mangekyō Sharingan was still gathering dust in his warehouse.
Back then, he had only absorbed the three pairs of Mangekyō Sharingan belonging to Uchiha Shisui, Uchiha Fugaku, and Obito Uchiha.
After taking out Uchiha Itachi's pair, he had kept them for Little Sasuke all this time.
The main reason was that life was too peaceful now, but he could hardly have one of Little Sasuke's friends or family—or Uchiha Mikoto—go die for him.

Otherwise, would that not be wasting a pair of Eternal Mangekyō?

Their fight was flashy enough, but both were holding back and had not truly gone
