"Letting Rin Nohara die like that would be a bit of a waste, but if she doesn't die, it'll be hard for Obito to awaken the Mangekyo. Having her trained back then was too hasty. If I'd left her alone, I wouldn't have so much to think about now."
Karn was somewhat torn. Yakushi Nonō had used considerable resources to train Rin Nohara to her current level. At Konoha Hospital, Rin Nohara's Medical Ninjutsu ranked among the top ten, and the Cursed Seal on her body had gradually faded, turning into Yin Release Chakra that influenced her thoughts.
When he had seen her in Konoha a few days earlier, Rin Nohara had greeted him with a smile, her face bearing the lively smile of a young girl. It seemed she had already moved on from Obito's death.
Nonō's assessment of Rin Nohara was certainly high. In the original story, Rin Nohara had completed an eye transplant in a very short time and could even use advanced Medical Ninjutsu like the Mystical Palm Technique. Among the ninja who had studied Medical Ninjutsu at the same time as her, there probably hadn't been anyone stronger.
It would be too much of a waste for her to die. I'd better find a way to save her.
Karn made up his mind, then prepared to craft a Magical Item. If he were there in person, he could treat injuries such as a pierced heart. As long as he kept her alive, either the serum or his blood could save her.
But Karn didn't have that much time to keep watch over Rin Nohara alone. Besides, fighting on the Land of Water front hadn't fully broken out yet, and Karn still had to visit other worlds. Who could know which day Madara Uchiha would act?
