Gasai has gone a whole new level of cuckoo bananas. She has taken over an old hotel and has Amano prisoner, as well as all the others.
But Kousaka (Amano's friend) suddenly gets upgraded to an Apprentice Diary Keeper. He busts everyone out.
How? Eighth has the ability to share.
Eighth's diary is a server: anyone who runs a blog on it gets the effect. She sends some of her users to take out Amano.
The defense plan is: if they cut cell service to the area, Eighth's Child Diaries will stop working, and they can take them out.
But it's a fakeout.
