Miyu's (probably) not Actually Transgender[]
Since the page has been locked and can't be edited I figured I'd bring this up here. But in chapter 3, Miyu quite clearly refers to himself as a guy, shown in the image on the side.
Most likely, Miyu would actually be a josō (女装, lit. women's clothing) or otokonoko (男の娘, lit. male girl or male daughter).
I think the page should be changed to something along these lines to be more accurate:
Miyu Shinohara (篠原 深雪 Shinohara Miyu?) is a student from Kisargi Academy Senior High School's classroom 2-9, a character in Corpseparty; Musume, and a victim of Heavenly Host.
A common fan interpretation is that Miyu is transgender, although Miyu refers to himself as a 'guy' when talking to Yuka in the infirmary, meaning he's most likely a crossdresser or josōko (女装子, lit. women's clothing). His friends do, however, use both male and female pronouns to refer to him, and he takes kindly to Yuka calling him "Onee-chan", meaning he is at the very least gender nonconforming.
