Might want to correct me if I'm wrong but I'm pretty sure the author is female, did the author use male pronounce during this chapter or am I missing something?
It's a fair question. I have now spent an embarrassing amount of time trying to figure out Mizu Asato's gender, and I'm still not sure.
"Asato" is definitely a female name, but this could easily be a pseudonym. On the other hand, Mizu's avatar in this chapter does strike me as distinctly male. I've also found a blog post of a fan who went to a Mizu Asato autograph signing, and they explicitly describe the author as a guy (the exact word they used is "oniisan", meaning older brother). I haven't been able to find a single picture of the author though, and the only video I've found only show their hands (which, for the record, look more male than female to me). None of the biographies I've come across mention much about their personal life, other than place of birth and blood type.
As for pronouns, the only first-person pronoun used by Mizu Asato in this chapter is a single instance of "watashi", which while somewhat feminine, can be used by both men and women. They also tend to avoid gendered pronouns in interviews, instead often opting for the neutral "jibun" (myself) where most people would use a normal first-person pronoun. On Twitter, they seem to use a mix of "watashi", "jibun", "boku",
and "ore", the latter two being distinctly male.
So yeah, I'm not sure. I actually did consider using female or neutral pronouns for this chapter, but ended up going for male pronouns mostly due to they way Mizu's avatar looks, and the scattered evidence I found of them being a guy. It could just be that I suck at Google though, and I certainly didn't read all 27k of their tweets to dig up more information. If anyone has evidence of them being (or identifying as) a woman, I'll go back and edit the chapter.
