Trope-tan/WMG

Trope-tan is secretly The Chessmaster in every work ever.
There are no Plot Holes, because Trope-tan did it. There are no Out Of Character Moments, because Trope-tan did it. Everything ever is caused by her manipulation.
 * Wrong! Tsukasa is.
 * Perhaps Trope-tan wants Tsukasa to think that, being the girl behind Tsukasa's actions...

Trope-tan has a long lost brother...
Since she has Mysterious Waif-tan and Black Magician Girl-tan as sisters...
 * To be more specific,
 * Who is himself in fact.

"The Wiki Witch of the Web" is, in fact, Trope-tan's true form.
And Trope-tan's "normal" self is merely a state that she takes while "the witch needs to rest for a bit"...

Wiki-Tan and Trope tan invoke Foe Yay intentionally

 * They're sweethearts but know they must keep their love hidden.

Trope-Tan will have an anime/manga.
Because someone had to say it.

Trope-Tan has some connection to Touhou
She seems to have the same Items of Power as befitting her nature, and general style as most of the known inhabitants of Gensoukyou. Perhaps she is a youkai?
 * She doesn't have to be a youkai to possess such a thing. I mean, look at Reimu and the other human cast members.

Trope-Tan Rule 34 is incoming
No exceptions.

Trope-Tan will be summoned by Louise at some point
because fan fic involving every other character under the suns been done, why not her?
