Read the manga, you'd be very surprised by his role lol. It goes like this: The writer for the manga had a injury to her arm and couldn't write. The anime producers apparently didn't feel like making filler, so they went ahead and did their own edits to the story line anyway, possibly asking for advice along the way. Of course, they didn't do it completely or that'd ruin the manga. Quite unfortunate too, it meant we never got to see Clear Note in animated form :(.
