Arachne subspeciesÂ
Habitat: secluded caves high in the mountainsÂ
Disposition: Cunning, malicious, lonelyÂ
Diet: Whatever prey they can catch, Spirt energy
A subspecies of Arachne once feared more than the Ushi-Oni of Zipangu. They are at the edge of extinction, having lost their homelands and most of their brood. Because of these circumstances, they chose to flee to highest peaks.
They have spider-like lower halves with a strange purple color that almost glows. Also, they master web-weavers, who can hid their webs well enough that when their prey realizes it, the Leng is already upon them.
In the current age, they also have become Mamono. They can no longer mate with other Leng spiders, which spells the demise for thier race. In desperation, they taken up the habit of capturing human men to mate with. To ensure the future of their species, they will lure men to thier nests, ensnare them with their webs, and frantically rape them.
Should a Leng Spider take a likng to a man they've captured, then she will become his wife, devoting herself to her man. The man may accept her love, giving himself to her, mind, body and soul. Together they will mate with eachother constantly, producing many offspring.
It should be noted that Leng spiders have a strong fear and mistrust of beastmen mamono, for in ages past the beastmen destroyed thier cities which drove the Leng spiders to near extinction. Stories of that event are passed from mother to child. Whenever a Leng spider sees a boy she likes near any beastgirls, she uses her webs to drag her darling away from the "filthy beastmen".
