ASCII Media Works‘ "Dengeki Bunko Bootleg" email newsletter has confirmed that the 16th volume of Isuna Hasekura‘s Spice and Wolf (Ōkami to Koshinryo) light novel series will be the final volume when it ships on February 10, 2011.
The Temple Knights website notes that there is still the possibility of future Spice and Wolf short stories. The 15th volume (pictured at right) had already confirmed in September that the series is "entering the final story arc at last." (The 15th and 16th volumes make up the two halves of the "Taiyō no Kinka" storyline.)
This reminds me that I still haven’t watched its anime.. >_>
Lucky that this is licensed in English.. I hope Hakushaku to Yousei will be published in English too!
*PS I put it in the Manga News section even if its a light novel.. Sorry about that. ^^”
