ダゴン娘

A monster that lives in the Northern Sea. Posing as a mermaid, she catches careless men who dare to get too close to her. Her mimicry isn't that great, but due to the obfuscation of the sea water, some men have been known to be tricked. In addition, due to living so close to the northern continent, she is quite a powerful monster. Once she catches a man, she uses her lower body to wrap around him, squeezing out his semen. An overly happy, innocent monster, she has been known to squeeze men to death with a carefree smile on her face. [From In-game Monsterpedia]
