I enjoyed Heaven's Memo Pad (Kamisama no Memochou). Twelve episodes well spent.
Thinking about it though, one thing does bother me. 12 episodes of a somewhat disjointed plot with some consistent elements, but largely just a set of self contained arcs like Black Lagoon or otherwise, and throughout none of it is the mystery of Alice even slightly unveiled. Who is she? How old is she? Why does she live alone over a ramen shop, and why does the shop owner choose to take care of her despite having no discernable relation past being some kind of mother figure? So many questions about the character who is more central to the plot than the MC we actually follow around from start to finish, and they fail to answer basically any of them.
I would read the light novels to find out more, but of the nine volumes, only the first four as well as the eighth have been fully translated, so I guess I'm out of luck there since I don't want to stop halfway or skip a third of the series and still end up missing out on the ending.
Otherwise it looks like it suffered a bit in reviews due to being similar to Gosick (which I plan on watching next), and only releasing the season after Gosick ended.
