While I am sure there is an infinite supply of this sort of thing out there under the dot-jp domain, this particular Haibane fanart gallery happened to be indexed by google. There are of course the usual obsessions with swimsuits, but what I found much more interesting were the concept art of scenes we never actually saw in the series, such as Reki taking her Flight, and Rakka’s cocoon bursting. And this scene of Raka and Reki in kimonos is just surreal, yet also somehow appropriate…
Of course, the Haibane rock band also, well, rocks. Go, Reki! And I note that the artist has a particular thing for Nemu…
Yeah, the whole Nemu/Santa thing strikes a severely dissonant chord in my head.
OTOH, he does know how to draw some stupendous cleavage.
