Of course it should be obvious given the character changes, the plot has been given the same loving treatment.
“Well, we soon realized the problem with Escaflowne,” Satan the S.H.I.T. Head responds, “was not that we changed it, but it was because we didn’t change it enough. With The Mystical Adventures of Gary Lightblade, we plan to thoroughly destroy and change Slayers in any and every way possible to alienate the hard-core anime viewers. After all, it is what we do best! :)”
And alienate they do! Here is current still-in-development show synopsis:
The Mystical Adventures of Gary Lightblade are the stories of the heroic knight Gary Lightblade, and his wacky and fun loving band of sidekicks as they try to overthrow the evil rule of the dark wizard Fresno. The Mystical Adventures of Gary Lightblade is great show for all ages, and thoroughly proves we hate all otaku.
Again, this synopsis is still in development. But I was able to confirm that any imagery that involves Gary in a dress will be taken out. Gary is a heroic knight and doesn’t stoop to such poor tactics.
Of course seeing what digital editing has transpired in such shows as Escaflowne and Tenchi Muyo, Slayers will have some digital editing. Luckily (or perhaps unluckily), I have obtained before and after shots of some of this digital editing.
