If you read between the lines of the first chapter, you could clearly come to a conclusion that Miyoi is maybe a youkai. During the buffet in the chapter, Suika mentions that the "worst youkai aren't those that are flashy but those that are discreet" (paraphrasing) and I think it references to Miyoi's identity. Also note that once Reimu left Geidontei after talking to the owner, she met Miyoi then completely forgot about why she came there in the first place after being talked into her theory which might be a hint of Miyoi's abilities.
I think that, considering the info we have now, I'd change "Human?" to "Youkai?" under these assumptions. We're still not 100% sure but the scale is slightly toward "youkai" than "human" in this case. Lebon14 (talk) 17:36, 26 November 2019 (UTC)
