By the way, for the curious,
volume 2 of the manga with Grimoire came in today. In case people are wondering what is "Grimoire" and what's in it, it's basically an "extras" book, with guest illustrations, guest comics, and a few short stories. One of the bigger "names" on the guest list is of course Peach-Pit, who contributed a rather salacious Shana illustration.
The guest comics are all very short, and range widely in quality. All in all, of course, it's not a bad bonus for only 320 Yen extra. The manga volume itself contains chapters 8 to 15.
