Location from Demon Slayer by Koyoharu Gotouge
A hidden medical practice where a demon physician treats human patients and researches the cure for demonhood — protected by Yushiro's concealment art.
Tamayo's clinic exists in a state of careful invisibility. Yushiro's concealment keeps it hidden from Muzan's network, while Tamayo treats human patients who know her only as a skilled doctor. The back rooms contain her real work: centuries of research into demon biology, blood samples, experimental compounds, and the slow development of the drugs that will eventually be used against Muzan. The clinic relocates periodically to avoid detection. Despite this transience, Tamayo maintains it with the permanence of someone who has decided that healing is her identity, regardless of what she technically is. Human patients receive excellent care. Demon research proceeds in parallel. The two activities aren't separate for her — they're the same project viewed from different angles.
A modest, clean medical clinic hidden within a residential area of Asakusa. The exterior is concealed by Yushiro's Blood Demon Art, making it invisible to both demons and humans unless Tamayo wishes to be found. Inside: traditional medical examination rooms, pharmaceutical work spaces, and a laboratory. Dried herbs hang from rafters. Glass vials and medical instruments line shelves. Warm lighting and clean surfaces suggest a physician who takes pride in her practice.
