Notes:

I'm assuming the "-neki" has to do with "aneki" (assuming to be "big sister"), sharing the "a" of Lucoa, which I assume is the sister version of "aniki" (big brother) because I figure that the words relating to brother/sister differ by swapping the "i" and "e".
(Did I Japanese gud? I'm right, right?)

More evidence that Quetzy (my superior nickname for her) should be treated as more of a big sister character than a pseudo-MILF.
