In my book CLAMPdown, in order to avoid giving away spoilers to series to readers who may be new to manga, I put some of the sections in mirror writing in order to prevent giving away the plot to some stories.
I have had comments on my Kickstarter that some people have had difficulty reading these passages, and thus below are the passages unflipped (i.e. the right way around).
The first is from p. 94-95, from the Tokyo Babylon chapter.
The second is p. 165-166, covering the first half of Magic Knight Rayearth.
The third, from p. 175, is about second half of Magic Knight Rayearth.
In the audiobook, the passages are also backwards, but I will ask the producer to provide me with these extracts unflipped to and post them up later.
