Flora

Ru's cousin. She is a beautiful female vampire with silver hair cut to the length of her neck, with a delicate, slender figure.
She visits Hiraku's Village to look for her cousin and settles down before winter.

Well-known in the world as an authority on pharmacy, she begins researching drugs with her cousin, but after learning the concept of bacteria from Hiraku, she started making miso and soy sauce, and later became known as the Queen of Fermented Foods.

Her laboratory was located in Hiraku's mansion at first, but since her research was only about fermentation, the smell became a problem, so it was sealed after the mansion was renovated, and instead a dedicated hut was built for her research and experiments. She is so immersed in her research that she brings furniture into this hut to make it her living space.
