Donovan is an Ancient Dwarf and a respected resident of the Big Tree Village, recognized for his expertise in alcohol and his role as the representative of the Ancient Dwarves who have joined the community. He first visited the village during the winter of the sixth year, arriving on his own initiative. Upon his arrival, he issued a friendly challenge to compare his own beverage with the one produced by the village. Following this tasting contest, he became a villager, integrating into the community without Hiraku Machio immediately noticing.

Donovan possesses a calm and reliable nature, making him a quiet but appreciated pillar of the Big Tree Village. His primary motivation is his passion for alcohol, as he enjoys tasting challenges and sharing his craft and knowledge with others. He respects Hiraku Machio for his personality and, most importantly, for his understanding of alcohol, which has fostered a relationship of trust and smooth cooperation between them.

In the story, Donovan serves as the representative for the Ancient Dwarves, including those who immigrated after him, coordinating their interests and their relationships with the rest of the village. Although he rarely fights, he possesses significant combat abilities, as demonstrated by his capacity to cross the Forest of Death alone and his victory in the warrior category of a competition.
