Hmm ! Using my top of the line, polished-over-the-years ability to analyse newhu silhouettes, here are my impression of the silhouettes :
-Lefthu seems to have sidetail kind of hairstyle going on and seems to be wearing some beret like kind of hat on the normal part of her hair as some kind of fashion statement ;
-Righthu's got antennae / antlers that seems to me like they are similar to the mythical
Kirin's ones and she also seems to have some sort of ...
flaming ... hockey bat-like thing ? Some suspicious looking flamey thing at any rate ;
-The thing laying on the bottom could probably be the scary part of a scythe and is connected to the straight thing between midhu and righthu. If such is the case, it's even possible for it to be connected to the flaming hockey bat thingy and the scythe's pole actually curves like Komachi's ... although the jagged part at its very end leaves me uncertain as to whether it is indeed a scythe that belongs to either midhu or rightu, or whether it's a furry or a spiky animal part of somehu (I don't think it belongs to lefthu cuz it stretches TOO far right and would obviously leave the screen)
-Midhu is one I am uncertain off
Also the ominous beast from title screen and the japanese title do not seem to me to be reflected in these silhouettes. Curious.
Anyway
Just my impressions
