Hmmm. Here I thought this was a generic setting and author threw the biggest curveball in yuri manga. A useful lesbian! Pundit-chan was a good bonus too.
I don't know if I'm feeling like this because I might not be remembering this story very well, but I don't recall Kurokawa ever giving signs of being this obsessed about Fujishiro. This chapter felt like a retcon to me, with a Kurokawa that was quite out-of-character.
