I thought, also, that Wordplay/Clockwork Lullaby/FML came out before mothy had really fleshed out his characters - and before he had a wide cast of Vocaloids available as "actors".

Undoubtedly, there were characters meant to be represented by a different Vocaloid than the one they ended up being played by (Irina seems like she was originally going to be a Meiko character given Julia Abelard being a Meiko character). Irina also sets a precedent for a character being played by multiple Vocaloids - something this mysterious singer may share.

I think she could be the person that's currently inhabiting the Clockwork Doll, since it can't be Eve anymore and it seems unlikely that the MOTC is an awakened vessel when there's no demon in it.
