Is it me, or does Koguma have some sort of disorder? Or is she just very innocent and ignorant? She brings up all sorts of rules that I can't imagine a Japanese high school having, and Hino always questions them, but she never gives up on them. For context, the school I taught at for years was what would be a magnet school in the US or an elite state school in the UK like Twyford C of E High School. We did have the rules like no stopping off anywhere before you got home and took off your uniform, and the teachers having to watch out for the students if they saw them outside of school, but it seemed to me like Koguma thought anything she noticed about Hino was illegal, basically.
