Mayudama acts as the attendant princess and messenger for the Inari spirit who reincarnates the protagonist into a fantasy realm. She possesses distinctive fox-like attributes, including animal ears and a tail. Following the protagonist's reincarnation, she joins his quest to discover and develop hot springs within this fantasy world. Her activities frequently involve sharing baths with the protagonist and other female characters, such as elves. A notable event occurs when the protagonist names a hot spring in an established onsen town "Mayudama's Onsen," visibly surprising her. This naming honors her significance within their hot spring development efforts. Her role consistently centers on facilitating and participating in the exploration and enjoyment of the fantasy world's hot springs alongside the protagonist and their growing group of companions.
