The end of this volume includes a “Letters to the Enchantress” section and an editor’s commentary; both of these are written by Carl Gustav Horn. I really enjoy Horn’s writing style for these sections, because he takes what could potentially be dry reading and makes it interesting and amusing for the reader. If you read the Oh My Goddess! manga volumes, I would also recommend reading Horn’s writing at the end.
Oh My Goddess! is off to a good start, and it’ll be interesting to see where the series goes next.
