Aquatic, freshwater monster girls, sahuagin or hangyojin are kuudere creatures that are quiet and emotionless - outside the bedroom. According to Fallen Maidens, their bathing suits have become a fashion item in the Demon Realms, where sahuagin-scale outfits are sold in sex shops as kinky costumes to be worn by other monster girls during sweet times with their mates.
Encyclopedia Entry
Aquatic monsters that live near the shores of bodies of fresh water such as rivers or marshes. They’re also called “hangyojin.” They are hunters who use their webbed hands and feet to swim around freely, accurately subduing prey in the water. Normally, they’re emotionless like fish, and they hardly ever speak, so reading their thoughts isn’t an easy thing to do.
Their personality completely changes when they are coupled with a man, the cold mask of a hunter disappears to make way for a wide range of loving expressions towards the man they are joined with.
When a man they’re fond of comes near the water’s edge, they move through the water, silently approaching him, then quickly leaping out to attack and begin a sexual assault. Contrary to the weak impressions they give off, intercourse is very passionate and intense. They appear to be mute and emotionless, but their love is revealed not through words or feelings, but through the sex itself. They express gratitude and fondness through cuddling and kissing, and when they want to express their love for a man, they push him down and jump right into sex. From an outsider’s perspective, it looks just like rape, but the wild sex is their greatest expression of love. In spite of their extremely quiet nature, they express their love for a man very frequently through kissing, fondling, and sex. As one can see, unlike their cold, silent exteriors, their interiors are actually hidden full of love and rich emotion.
Furthermore, while they’re engaged in sex with the man they love their ordinarily emotionless expression undergoes an unbelievable change, revealing great ecstasy and rich emotion. Even though they don’t talk too much ordinarily, during mating, they naturally start to utter words of temptation and moan in ecstasy endlessly.
