Only in Japan for now, sadly
The Witch and the Hundred Knights is nearly upon us, and to celebrate, NIS is doing a limited edition run of the game in Japan. It'll including a 44-page hardcover art book, an adorable figurine of the Witch herself, and the soundtrack.
As a general rule, I dig how Atlus and NIS keeps things simple when it comes to collectible releases -- an artbook, a soundtrack, and maybe one or two small extras. That's how you do it. The game itself is slated for release on July 25th in Japan -- hopefully we'll get more localization info soon.
