I don't even own a copy of Tsukikagerou (much less know the story), but I really like the character designs, Yuzu's especially.
This took days to make because the original background (autumn leaves) was difficult to separate...also, I toyed around with different backgrounds for about two hours before completely giving up. It's simpler than I would like, but there wasn't anything else I could think of to make it better. This is pretty much one of the "Meh, I should try making a new one with this art in a year or so" cases. If this is your kind of thing, enjoy.
