For what it's worth, I have created a page over on TvTropes for your "Ojamajo Doremi: Rise of the Shadows" fic. I will provide a link:
tvtropes.org/pmwiki/pmwiki.php…If, for whatever reason, you wish for me to remove it, then I will have to say that is not possible. The staff there will not allow me (or anyone else, for that matter) to do such a thing. If someone even tries, the mods will undo the deletion and suspend whomever did it, and I have no intention of getting myself suspended just because you don't want anything on your work.
If anything, you should feel honored that someone made something like this on your works. In fact, it's the first "Ojamajo Doremi" fanfic to get a Tropes page, so that's a pretty huge honor right there.
