I've always use to believe that other part of Obito's body aka IT zetsu or Hashirama cell preventing him to getting damage from Ms.

Yet i know its never mentioned,but that's only logical thing to me.

Since seeing Obito mention for Danzo being able to handle many Sharingans due Hashirama cells. Its only thing i can assume why Obito gets no damage.
