Ninjas had always had a tradition of dealing with the bodies of the dead, especially powerful ninjas. The more exceptional a ninja was, the greater the research value of their body. Otherwise, the major ninja villages would not have dedicated Anbu units tasked with hunting down fleeing ninjas and bringing them back for the corpse disposal division to destroy.
That was true enough—
But when they saw with their own eyes the right half of Shimura Danzō's body lose control and transform into a massive tree—revealing that beneath the bandages he had kept wrapped around his right arm for years, there were living Three Tomoe Sharingan embedded one after another—even Utatane Koharu and Mitokado Homura, hardened by the cruel traditions of the ninja world, could not help frowning.
The Sharingan was an excellent "ninja tool," and it was understandable that one might be unable to resist using it. But there was no need to use it in such a disgusting, bizarre, and grotesque way—couldn't he just transplant it into an eye socket like Kakashi had?
"—" Tsunade stared at Danzō's right arm, left within the out-of-control tree. At what had originally been the shoulder, there was clearly a pale human face. Though its eyes were closed and it had only features, no hair, there was no doubt that it was the face of her grandfather, Hashirama Senju.
Transplanting the First's cells or conducting experiments, while unpleasant to her, was not something Tsunade was old-fashioned enough to ban outright. But Danzō, couldn't he have done it without making it so disgusting?
Shimura Danzō panted as he covered the broken cross-section at his right shoulder, like a snapped branch. Faced with the silent stares of Tsunade and the other two, he neither dodged nor avoided them, nor did he offer an explanation.
