>The most popular confirmed Touhou fan, could be a celebrity or something
Toby Fox, almost certainly. He is upfront about how much Touhou inspired Undertale and Deltarune's fighting style. He's even linked up with ZUN at least a few times. Hundreds of thousands of people all over the world worship that man, I'd even argue it's more intense than ZUN worship because ZUN doesn't directly interact with the community through social media as much, and Undertale/Deltarune fans are younger and more impressionable in general
