Frostvine

Frostvine is an old woman who has dedicated the majority of her life to the creation of Doll Homunculi. She is the creator of Athena 2.0 and the master of Tama the cat girl, though she can often get angry at her oft-distracted assistant. She made her first appearance in Rance 4, where she lives at the very top of one of the Ylapu towers. When Rance encounters her, and despite his loud protests, she tells him of her life's work, Doll/android creation. Though Frostvine had already created a doll before, Athena 1.0, as the ultimate toy for a child, it's personality was "too human", and the creature eventually left with a Ham Bambara. To avoid this set-back in her newer creations, she asked Rance for two ingredients, the "honey" of both a devil and an angel, in exchange for which Rance could take the prototype of the new procedure, Athena 2.0.

Rance was able to provide the two ingredients by convincing Willis Fujisaki that her honey was necessary for a quest to save the world, and by simply summoning Ferris and extracting it from her after sex. However, in the latter case, the honey was also mixed with Rance's semen.

When Rance returns, Frostvine uses the ingredients to finish her Athena, but while Frostvine is ecstatic about her success, Athena turns out to have fairly low intelligence, probably due to an imbalance caused by the extra ingredient. Despite this, Rance gladly takes her and brings her back to his headquarter to H her, only to find out that nipples were apparently sold separately. An enraged Rance returns her to Frostvine, and while she promptly adds the missing touches, a second attempt reveals that the doll also lacked sexual organs.

Frostvine is an odd individual, utterly dedicated to her life's work, doll-making, to the exclusion of apparently everything else. However, she has grown extremely adept at her craft, with her dolls all possessing intelligence despite being completely artificial and being virtually indistinguishable from humans, even possessing all elements from the Planner Scenario, such as skill levels. As seen with Athena 2.0, they can also have great combat capabilities, being able to keep up with Rance in his many adventures, such as taking down Toushin Upsilon. However, despite their great strength, they seem to be stuck at level 1, making it impossible for her to improve her combat abilities. But because of her only focusing on the dolls, Frostvine is extremely reliant on Tama for taking care of everything else, be it cooking, cleaning, or running her store, which is how she funds her experiments.
