With Midori on this, the boy not mindbroken and killed isn't a surprise, one of the Midori fans joked about the chances of mindbroken husby being some unholy chimaera made out of Ran, Chen and Yukari murdered lovers... Maybe that one is on the cards xD
@vPhone: It's not like she had a choice. Yukari ordered her to do it and it was something that was bound to happen from the start. Ran got involved with the guy despite knowing this. The only thing that confuses me is that Ran didn't put up much of a fight over it, but then again this is Yukari we're dealing with on top of the whole "shikigami obey their master's commands" thing.
