Random fun fact for those of you interested. (and for those who know that Okiku derives from an actual Japanese ghost-story)
The cover of the third chapter, showing Okiku standing in some sort of landscape in front of a well with her hands brought up to her face. That cover is a direct reference to a real-life painting.
If you google “Tsukioka Yoshitoshi’s Okiku”, you should see the original painting, on which the chapter’s cover is based.
