A kigyo has a seahorse-like lower body and a round, colourful face dominated by wide, staring eyes and hideous fangs. A typical kigyo is seven feet long from its head to the tip of its tail and weighs 190 pounds.
Kigyos have the ability to create powerful whirlpools that latch on to multiple creatures and holding them in place until they either drown or fall victim to its other attacks.
Like other oni, kigyos are hateful, vengeful and prey on mortals out of spite and malice. They enjoy seeing their victims drown and are said to be both drawn to the sites of and responsible for numerous deaths at sea.
Kigyos also feel superiority at making an enemy willingly give up something valued in exchange for its life or that of a loved one. Many kigyos develop obsessions with a single type of ransom, such as firstborn children, spouses, organs, or, rarely, pure material wealth; it is possible to track down an individual kigyo by the specifics of its ransoms.
Kigyos rarely cooperate with each other, preferring to live solitarily. Disguised as an aquatic or shore-dwelling humanoid and pretending to be a castaway or injured, a kigyo attempts to seduce unsuspecting mortals and tricks them into bringing itself onto its victim's ships or into their communities. The kigyo then secretly amasses stolen items of value, reveals itself to its victims and demands a ransom of something far more precious for the items' return.
Kigyos are filled with hatred, especially for kami and particularly suijins, to the point of forming hunting parties to seek out and destroy them. These raiding bands constitute the few large groups of kigyos on Golarion. In these teams, half of the kigyos hold foes in place with their grasping eddies, leaving the killing to the rest.
