Tomorrow didn't help resolve the mystery! XD either that was Mahiru showing she cared which was really sweet and selfless, or was a cunning demon trick, which would have worked if not for Guren making the decision.

Yet for the first time we know of with what happened does this mean Mahiru herself can speak wit Guren rather then the combined Mahiru-no-Yo? Classic case of one question may be answered but more have arisen!
