Dé Ryúa's Porcelain Water is a magic potion described in detail in Monster Girl Encyclopedia World Guide - Side III book.
Book Entry
A magical beverage made from natural spring water collected in Dé Ryúa combined with a deep-sea witch’s magic! It’s colorless and transparent, but emits a thick, mysterious glow!
This water, considered a treasure to song maidens, puts one’s voice in tune once they’ve drunk it, but typical of Dé Ryúa, that voice becomes just as bewitching as a lewdly gasping voice, and their singing invites desire with its panting sexiness, and on the other hand, their panting during intercourse steals a man’s heart just like a beautiful singing voice does!
It’s a popular item for naughty song maidens that want to use their songs to turn on the man they’ve set their eyes on, but it’s also an ideal present for monsters that aren’t song maidens❤
Enjoy your night with your song maiden, and propose to Dé Ryúa’s song maidens![1]
