Where is everybody?

We see at the end of the previous volume the revelation of debatably the most shocking death so far, which marked a shift in the series. That was episode 7. Cue episode 8, where we are introduced to an all new set of characters. This episode I felt was better than the following two (which do basically the same thing), but overall it just got pretty confusing. The last episode on here deals with making a programme based on the character Maromi, but even the creator, Tsukiko Sagi, is not shown. That is pretty disappointing especially when compared with volume 2, but on the flipside no one can accuse this anime of becoming stagnant, and I suppose it was time to move on.
