No. Her anti-regen is having to do with being in the flesh. A real time wound like a cut or a bullet hole. Edo tensei, they are not in the flesh. It’s a mimic of being in the flesh. Major difference. That’s why there isn’t any blood when they form again. It’s akin to let’s say, a spell… She can stop the real thing, not the spell version, if that makes any sense. It’s not anti-reanimating, it’s anti-wound healing. Edo tensei do not get or have actual wound. They’re not alive. They are just a shell. It’s not about stopping the shell it’s about stopping the spell.
