That’s exactly what happened in Japan this summer, when the Natori City Health Centre in Miyagi Prefecture enlisted virtual YouTuber Sana Natori to put out the call asking for blood donations.

When a 17-year-old who lives in a sanitarium with bandaged wrists and a fang tooth asks for blood, fans come running from around the country.
