And how do you related blood to Reincarnated Devils being more prone to injuries? Sona was just having Saji suck out Ise's blood till the point where he needs to have blood replenish his blood. It has nothing to do with Reincarnated Devils being more prone to injuries while Pure Devil don't.

It is just using a weakness of a person, Ise did the same against Riser too. Does it mean that Pure-blooded Devils are more prone to injuries as well?
