Spice and Wolf is rather unique for a fantasy anime; it doesn't focus on fighting, magic, action ect it focuses more on religion, trade, economics, money amongest other thing. The charm of the seires is the character Holo and Lawrence, watching them chat and interact with each other is were the joy of the series comes from, they both bring out the worst and best in each other. They're the perfect duo.
