With his preparations complete, Tetsuya closed his eyes. When he opened them again...
His blood-red Eternal Mangekyō Sharingan had vanished, replaced by a pair of golden Rinnegan, each bearing six tomoe arranged in an inverted triangle.
"How did that happen? That's impossible!"
Madara Uchiha watched Tetsuya simply close his eyes and open them again, and his eyes had evolved into the Rinnegan!
He suddenly felt a little ridiculous. Back then, after obtaining Hashirama cells, he had spent so long in the cave, only awakening his Rinnegan when his life was nearly at its end.
Yet now, Tetsuya had awakened his right before his eyes. It left him feeling rather bitter.
It wasn't that he couldn't accept the miraculous things Tetsuya could do. It was just that watching someone else effortlessly accomplish something he had once poured so much effort into was far too crushing.
"What's so impossible about it? Haven't you seen enough unbelievable things while hanging around me?"
"..."
Madara Uchiha couldn't argue. After all, Tetsuya had accomplished far too many unbelievable things.
"All right, enough of that. I'll lend you a Rinnegan to play with for now. Once we get your own Rinnegan back, we'll swap them back."
As he spoke, Tetsuya plucked out his right eye.
Seeing this, Madara Uchiha stopped dwelling on it. After all, the most important thing now was to use this Rinnegan's power to become the Ten-Tails Jinchuriki!
He reached up and removed his own right eye as well. Come to think of it, the right eye he currently had wasn't even his.
The eye he removed was the Mangekyō Sharingan he had traded his Rinnegan to Obito for.
Tetsuya recognized its ability from the Mangekyō pattern. The Kamui Mangekyō. Isn't this Obito's eye?
Right, Old Madara traded his Rinnegan for it earlier.
