Wolf and Amber Melancholy

Wolf and Amber Melancholy is an original video animation (OVA) for the Spice and Wolf anime that not only bridges the plot of the first and second seasons but also marks the transition in the show's production from Imagin to Brain's Base.

Synopsis
Before leaving Ruvinheigen, Holo, Lawrence, and Nora have a celebratory dinner together, but Holo's animosity toward Nora prevents her from enjoying it. During the meal, Holo falls ill due to fatigue and is forced to rest for a few days. She dreams and reminisces about her past and her journey so far with Lawrence, realizing her affection for him is intensifying. Lawrence treats Holo's fever and fatigue by feeding her and balancing the four classical states: hot, cold, dry, and wet. Over the course of her sickness, Holo grows closer to Lawrence, but Holo's aversion (or jealousy) toward Nora continues to cause problems. Nora visits Holo, however, and the two make amends after sharing a joke at Lawrence's expense.
