The Spectacles of Eros is a powerful item that is only seen in Rachel Alucard's gag ending in BlazBlue: Continuum Shift.

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 Units (Lambda and Noel) and a Nox Nyctores (Nirvana) fall under its effects, subsequently making them fall in love with Ragna against his will.

Appearance
The spectacles themselves appear as a pair of pink hued, butterfly-shaped glasses. 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.

Trivia

 * Jin Kisaragi also fell under the Spectacle's power despite being a man. However, as correctly stated by Rachel herself, his feelings didn't really need that much of a modification to fall for Ragna.
 * Strangely, Rachel was not affected by the Spectacles' influence, but it is possible she already fell in love with him.
