Spice and Wolf Manga Uncensored

You can find the uncensored versions of this panel and others through a quick google search.

Some versions of the Spice and Wolf manga have full nudity and some versions are censored. Interestingly enough it seems that the US versions have nudity and the Japanese presses don't. Either way it's not "sexual" nudity in the manga. She's naked but not sleeping with Lawrence or anything. The artist of the manga is Kourme Keito and they draws other hentai manga. It seems like none of Kourme Keito's full Hentai-level doujinshis are of Holo but Kourme Keito does create non-Hentai drawings of Holo.
