Spice and Wolf, Vol. 4 (manga)

After turning a healthy profit following his adventures in Pasloe, Kraft Lawrence is eager to reinvest his capital with an eye to the future. When the deal turns sour, though, Lawrence finds himself deeply in debt and facing a very bleak future indeed. Luckily, Holo is at his side with a risky (and less than legal) scheme that may just save the merchant's neck and a promise that, no matter what, she will guarantee his safety. Is their relationship blossoming into something more than just a business arrangement?
