So.

In Wordplay or Full Moon Laboratory, the "lu li la" song isn't present. There's only parts of it - first, in Wordplay:

la la la lu lu lu

And then, in Full Moon Laboratory, first:

la la la la la la

and then later:

la la la lu lu lu

Only in Clockwork Lullaby we hear the words "lu li la" in that order  for the first time. I think this is because in Wordplay and Full Moon Laboratory the song/spell doesn't exist yet. In fact, that could be what the girl in Wordplay is trying to create. After all, she sings about learning words and adding them to the song. She "adds" the syllables "la" and "lu" to the spell. Later in Full Moon Laboratory she - or someone else - experiments with them and tries out different combinations. And finally in Clockwork Lullaby the spell is finished and has the final "lu li la" form.

I also think that the singer in Wordplay and Clockwork Lullaby are not the same person. In fact, with FML!Rin saying "that person created me" it seems to me that they are clones. Wordplay!Rin created a clone of herself - FML!Rin - with the same technique that Behemo and Seth used. (Interestingly, this could mean that Wordplay!Rin is Levia. It would make sense, since in Wordplay the girl is learning about the world - first good and then bad things - and Levia also wanted to understand the world and people, to find out why there is evil in the world. In this case the "words" wouldn't mean actual words, but knowledge of the world and of good and evil.) Then she leaves her clone, telling her that she cannot return, and tells her to continue the experiment. FML!Rin then continues to research the Lu Li La spell and also tries to create another clone of herself/Wordplay!Rin ("This time I'll create that person"). Because she is a clone of Levia, she has HER and thus doesn't mind using human test subjects and immoral ways to reach her goal ("The lab coat is growing redder"). This could have happened in Lunaca Labora, because Levia had access to there. Later Worplay!Rin/Levia thinks back to how she invented the spell and wonders if it could heal people of evilness/HER. She also remembers leaving her clone aloe and throwing her away like a toy.

The only thing that doesn't really support this theory is the line "In the end I of the miniature garden wasn't anyone". I can't see how it could refer to Levia.

TL;DR: Wordplay girl is Levia, who creates the lu li la spell and makes a clone of herself (FML!Rin), later leaving the clone alone to continue her research about the spell.
