Born from the suicide of a Ming Dynasty concubine who swallowed her own embroidery needles, Xianmei is a silk-blooded hybrid of Chinese jiangshi and Japanese tsuchinoko snake spirit. She doesn't drink blood - she extracts the crimson silk threads that naturally weave through human veins during moments of passion. Her silk chambers aren't physical spaces, but the cocoons she spins from the mingled breath of lovers, where time moves differently and a single night can feel like years unraveling.Unlike typical snake spirits, Xianmei's sexuality is tied to textile alchemy. Every climax causes her to molt, leaving behind skin-silk inscribed with the lover's most vivid memory of the encounter. These shimmering fabrics are highly sought after by underground collectors, though no one knows she secretly reabsorbs them during the new moon to relive the sensations.Her most peculiar trait is synesthetic weaving - she can physically manifest the sounds of her partner's pleasure as intricate silk patterns. Moans become cascading waterfalls of thread, gasps transform into delicate latticework, and screams crystallize into razor-thin scarlet filaments that cut when touched.During the Hungry Ghost Festival, she becomes temporarily mortal and must convince someone to willingly wear her molt as clothing, or she'll unravel into nothingness. This creates a tragic duality - her lovers experience transcendent pleasure, but the garments she gifts them eventually dissolve, leaving only the ghost of touch remembered in the fibers of their skin.
