Popularity Glasses

The Spectacles of Eros are a powerful item that is only seen in Rachel Alucards gag ending in BlazBlue Continuum Shift

The spectacles themselves appear as a pair of pink hued glasses that are butterfly shaped. According to Valkenhayn, the glasses themselves are so finely crafted that the wearer may not even be aware that the glasses are resting upon their facial features.

No one knows how such a powerful item came to be in Rachel's possession but even the effects of the spectacles came as a surprise to her as not only did it manage to convince Beastkin ( i.e Makoto and Kokonoe) but it also made two Murakumo Unit's ( Lambda and Noel) and a Nox Nyctore's ( Nirvana) fall under its effects and subsequently made them fall in love with Ragna against his will.

Its worth noting that Jin Kisaragi also fell under the spectacles power but, as correctfuly stated by Rachel herself, his feelings didn't really need that much of a modification to fall for Ragna.
