User blog comment:Soshosaur/Sesshomaru and Rin/@comment-5126314-20130814185253

It was not written by Rumiko Takahashi. Therefore it is not canon and cannot be included in an article as a main source. It could be mentioned under trivia or something, but it reflects no way onto Rin or Sesshomaru of the Manga or Anime, which are the 2 main sources for Inuyasha wiki. The Special CD might as well be fan-fiction, because it wasn't from Takahashi herself.
