Ruru Hikaru: Vampire Memories

Ruru Ogawa, a high school girl, is told that she has a "blood affinity," a special constitution that we once called "vampires." Ruru is sent to work with Ed, a “blood lore master” who can absorb the memories of the people he sucks blood from. A fantasy story where memories of traditional crafting skills are passed on through blood! (Source: Kurage Bunch, translated)
