Yao Bikuni

A being that attained immortality after consuming mermaid flesh. Lurking in the shallows, she jumps out of the water towards unsuspecting adventurers with weapon in hand. Cursed by the flesh of the mermaid she consumed, she became a mermaid herself; a monster destined to roam the ocean forever. It is said that she attacks humans in order to find one with the strength to put an end to her misery.
