“An Arachne of the highest class, which boasts tremendous power. Very few of them exist, and it is said the the blood of their ancient progenitor flows through them. Many of them follow the Spider Princess and are serving as her bodyguards.
When capturing a man, she covers his entire body in threads that induce ecstasy. While he is immersed in the ecstasy of being wrapped in her cocoon, she will violate him. The man will be preserved in the cocoon and she will suck him whenever she feels like it. However, Atlach-Nacha can be very brutal, and will devour the man if she gets bored of him. With a brutal nature hidden under a polite attitude, she is an incredibly dangerous monster.”

"Eaten by a spider, like an insect. Do you now know what it's like to be sucked dry? Atlach-Nacha is a powerful spider monster. She uses troublesome thunder and time magic. Her attribute resistances are all average. But her abnormal status defense is high, so those aren't reliable. Now go, oh Brave Luka. I'm getting hungry for some dried food... Ah, I'm not referring to you."
