Geez, Yuki has to be able to do at least something, how can he let Yuno do all the work for him so he can survive... So that's the power of the 7th, for some reason their diaries seems somewhat like Yuno's. Now they took hold of Yuki's and Yuno's diaries, they can die at any moment..but since their the main and I see chapters to come, not likely. Then again, those diaries can be used effectively against them. What's going to happen now that Minene is part of this?
