Ru's cousin, she's a striking vampire with silver hair cut short at the neck and a delicate, slender build. She showed up at Hiraku's Village looking for Ru and ended up staying through the winter.
She had already made a name for herself as a pharmacy expert before arriving, and initially collaborated with her cousin on drug research. But everything changed once Hiraku introduced her to the concept of bacteria—she pivoted hard into fermentation, experimenting with miso and soy sauce until she basically became the go-to authority on fermented foods.
Her early lab was set up in Hiraku's mansion, though the fermentation work created serious smell problems. After the mansion got renovated, they sealed off her space and built her a dedicated hut instead. She's so absorbed in her research that she's basically turned the hut into her living quarters, hauling in furniture and everything. At this point, the lab is less "workplace" and more "home base for her experiments."
