It took me close to three years to finish it. I would get distracted, put it down, and pick it up again much later, months later. The surrealness of the story reminds me a lot of other Japanese media that I never really fully understand. I chalked it up to the usual "the Japanese are truly mad" maxim, but after finishing the book, I suppose my opinion changed a little. The book is almost exclusively inspired by Western stories, music, and tropes. It has shades of Alice in Wonderland, cyberpunk, casual sexual themes, jazz and rock and roll. What makes the book look so foreign to me is that those stories are getting retold all mish-mashed together in a dream-like state with a dash of Japanese tropes. In the end I enjoyed it, but I don't think I really understood it, and I don't think I can explain why I enjoyed it. Can anyone explain it to me?
