So how in the hell did Hiruzen draw up the blood necessary to kuchiyose Enma in the first place?! Reanimated shinobi can bleed as well. See Itachi when he cast Amaterasu, his right eye bled even though he was an Edo. Same for Gengetsu's summoning of the Giant Clam.

Hmm. So edotensei alters the host body's DNA as well, then.
