The 12th volume of Keito Koume's manga adaptation of Isuna Hasekura's Spice and Wolf (Ōkami to Kōshinryō) light novels revealed on Thursday that the manga series will enter its final arc in the 13th volume.

MediaWorks announced the manga adaptation in 2007, and the series debuted in the November issue of Kadokawa's Dengeki Maoh magazine that year. New chapters are serialized monthly in the magazine. Jū Ayakura, who illustrated the Spice and Wolf novels, designed the characters for the manga. The North American publisher Yen Press licensed the manga in 2009 and will ship the 11th volume this September.

The Spice and Wolf story follows a peddler who discovers a wolf girl who wants to return to her northern home after serving as a town's goddess of harvest for many years. The peddler strikes a deal to bring the wolf girl north, and she brings him both prosperity and unwanted attention from the church.

MediaWorks published the novels Japan, and shipped the 16th and final volume in February 2011. Yen Press licensed the novels in September 2008, and will ship the final volume in December.
