This is a really great idea but I pitty the poor fella..
As it is in literature, stage arts or film making; What is so unique in the fantasy genre is that the creator of a piece is only the owner by right and is not allways the main inovator in the further development of the world he built.
Take George Lucas for example; He wrote the books for the original star wars movies and gave a few pointers to the people who helped him realize his visions but as for the many twists and turns in the plot in the future and past were all written by writers who so happened to be fans.
My points is.... I think, that if we send this letter to Yagi with all of those questions he'll probably be a bit confused if not shocked
and if not, then it's only because he had recieved hundreds of letters beforehand from crazy japanese fans. Who in the world would've thought that fans of HIS masterpiece know more about it that he does...
