What's happening to DGM? Really, it just seems like boring filler. Well, not boring. If anything, it's hillarious and kinda creepy. Please note this relates to chapters 159-162.
The funny: Allen's long hair, chibified Lavi and Kanda, Lenalee acting like a cat, Bookman's hair turning into bunny ears, and how everyone's treating Koumi for the "Koumvitan D".
The kinda creepy: the ghost posessing Reever and how the "zombie's" transfer the disease.

Well, that's all for now. I'll write more about my opinions on what's happening.
