Stowing Ninomiya Hao's body away, Otoha sealed it inside a scroll, intending to bring it back to the village for burial.
"They can't have gone far."
Katsuki opened his eyes. Kushina's lingering scent was exceptionally conspicuous all along the way. Moreover, the stirring of his bloodline filled him with sorrow. The Human-Human Fruit had undergone changes after combining with the Uzumaki bloodline—changes even he found difficult to understand.
"Catch up to them. I'm going to kill them. Kill them all."
Otoha growled in a low voice, his hands clenched into fists. His pupils transformed into a blazing crimson, black tomoe slowly rotating within them. His murderous intent boiled over, making it impossible to meet his gaze.
"Otoha, you awakened your eyes?"
Though he could barely contain his grief over Ninomiya Hao's death, Katsuki was still overjoyed at the sight of Otoha's blood-red eyes. He was sincerely happy for his friend. Once Otoha returned to the village, he would surely receive the clan's full support. Only then would the Uchiha name truly fall upon him.
Awakening one's eyes was of immense importance to the Uchiha Clan. There was even a saying in the village: only those who awakened the Sharingan were true Uchiha. That alone showed just how significant it was.
And Otoha's right eye actually bore two tomoe, leaving even Katsuki dumbfounded.
He was close with Otoha and Otome. After spending so much time together, he knew quite a bit about the Uchiha. He knew that awakening one's eyes was only the first step; training a Kekkei Genkai was anything but easy. Many Uchiha went their entire lives with nothing more than two tomoe in both eyes.
For Otoha to have one two-tomoe eye the moment he awakened his eyes meant he had already won at the starting line.
