I wonder why Konan was not reanimated in Kabuto's Edo Tensei considering she's an akatsuki member, S-rank criminal and one of the most powerful kunoichi in the narutoverse. Maybe she's still alive or something, maybe she will show up in Boruto. She can be seen unconscious in her last scene tho, but who knows, she was never seen exactly been killed by obito.
I would say this has a direct correlation to the dance of the shinigami, being that she relied on that ability quite often and I would say that contributed to her not getting reanimated. When She died it showed that she had been dispersed into several sheets of paper and she was also under a genjutsu that was casted by Obito, thus ensuring her death. And even if she had survived Obito would have definitely sensed her and killed her off with his newly found rinnegan/Sharingan.
