I loved vol. 1 of the manga but as it kept going it got very one-note-joke. As one-note-jokes the chapters were fun but did not sustain reading it as a series. It never really put in the characterization work the concept needed to be more than that, unless it does after the point where I stopped.

That said I'd still be up for manga-based yuletide fic that *does* put in some characterization!
