Context: Medusa suddenly starts talking like she's doing a TV ad for some product.
makai-juu minna de makai-shiki senrigan doroppusu 魔界中みんなで魔界式千里眼ドロップス [Let's eat] demon-world-style clairvoyance drops with everyone in the demon world. (incomplete sentence.)
This makes no sense, so it's clearly right-to-left.
The fact that the drops use a right-to-left label implies it's some old, or old-fashioned, product, which is very likely considering characters from the demon world are thousands of years old.
