He sees the frown on the scientist’s lips, and can’t bring himself to care. He’s sure that his words brought some amount of hurt, but then... Does it really matter? Probably not. He allows Rin to approach and inspect the hole that he’s been left with, an ugly reminder of the fact that Izuru is no more than a walking, talking corpse.
“No. People would have lived, and people would have died, regardless of my own participation. Most of those I cared for were elsewhere. There is no way I would have been able to protect them. The Third Division would have continued to stand. The war would have been won without me. There was no need for me to be revived, and there is no need for the continuation of this farce.”
Ah, now the boy is prodding at the healing tissue. He can’t feel it, however. He only knows because he can see it. But then, is it truly healing? Or is it just an illusion brought on by Mayuri’s desire to have a new puppet? Izuru isn’t sure. Nor is he convinced that he cares, either.
Hearing the proclamation of gratefulness, he can only snort in disdain. His actions were meaningless, and had made no true difference in who won and who lost. Who lived and who died. His life had ended, and yet he’s still here. It’s meaningless.
He doesn’t even look at the candy as it’s offered, choosing instead to ignore it. “I am not strong.” Those who are strong do not die, especially not in such a foolish way as he had. “I am weak. I was always weak.” He has no desire to live. He only wants to rest, now. Eternally.
