"Mm!"
Tsunade hesitantly nodded.
The reason for her hesitation was that, judging from Yakumo's examination data, her eyes seemed to be slightly out of sync with her body.
But the mismatch wasn't severe enough to suggest an organ transplant.
Tsunade, a master of Medical Ninjutsu, had performed dozens upon dozens of organ transplants—nearly a hundred. She knew very well that if the eyes had entered Yakumo's body through a transplant, the rejection would be far more pronounced than it was now. She would have recognized it at a glance.
But the data she had obtained only showed that the eyes were slightly out of sync with Yakumo's body.
Considering that these eyes might be a Dojutsu Kekkei Genkai Yakumo had just awakened, this kind of mismatch wasn't impossible.
After all, history had seen the emergence of new Dojutsu Kekkei Genkai through accidental mutations, such as the Red Eye and the Ketsuryūgan.
And because so much time had passed, it was difficult to verify the physical data of the first shinobi to awaken the Red Eye or the first to awaken the Ketsuryūgan. So even Tsunade couldn't reach a definitive conclusion on this matter.
Obviously,
the Red Dragon Eye's passive ability to control blood and draw out its host's potential had misled Tsunade.
Even after the transplant was complete, the Red Dragon Eye had continued to affect Yakumo's body. Combined with its unique abilities, this meant there was no significant rejection between it and Yakumo's body.
If it had been Orochimaru or one of those madmen like Hiruko, they wouldn't have ruled out the possibility of a transplant so quickly.
But it was precisely Tsunade's exceptional skill in Medical Ninjutsu that had led her to study organ rejection in great depth.
And it was that very expertise that had influenced her
