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 Nanaya 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 the Bloodedge against his will.
In BlazBlue: Chronophantasma, in the story mode's gag ending in Episode 7, an upgraded version of the Spectacles of Eros, known as Spectacles of Eros Mk. II (モテメガネ A Mote Megane A), appears. Just like the previous version back in BlazBlue: Continuum Shift, it made all the girls fall in love with Ragna. However unlike the previous version, this time it even made Tsubaki Yayoi and Ignis fall in love with Ragna. When Celica A. Mercury appeared at the scene, it turned out she was unaffected by the Spectacles of Eros Mk. II, where she admits that she really loves Ragna. This made all the girls become jealous, which created flames of jealousy that were close to exploding, prompting Rachel warn Celica to run away, before the flames exploded.
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.
- The Japanese name of the Spectacles of Eros is written in katakana instead of kanji, but it most likely stands for Possessed/Popularity Glasses (持て眼鏡 Mote Megane).
- Jin Kisaragi also fell under the Spectacle's power despite being a man. However, as correctly stated by Rachel herself, his feelings did not really need that much of a modification to fall for Ragna.
- Strangely, Rachel was not affected by the Spectacles' influence, but it is possible that she already fell in love with him. Tsubaki, Taokaka, Ignis, Saya, Torakaka and Linhua were also not shown to be affected. However, in BlazBlue: Chronophantasma, Tsubaki and Ignis are affected, as well as Bullet. Nu -No. 13-, Saya, Taokaka, Torakaka, Phantom and, oddly this time, Platinum and Lambda were not affected; neither was Celica but this is because she confessed to already loving Ragna and was, thus, unaffected.
