An Arachne (a demi-human monster) with the lower body of a spider. She spins webs in the forest using silk produced within her body to capture humans, turning them into cocoons to drain their life force. Humans caught in her web can never escape. Kiriritos binds their entire bodies in silk, restraining them tighter and tighter... until they are fully cocooned, their life force drained until they die.

"You're so lucky to have stumbled into my web, aren't you? ♡" "Your life force... slurp, slurp... ahh ♡ I can feel it through the silk ♡ You really don't want to die, do you? ♡" "Wrapped up so tight, you can't even move a finger anymore... ♡"
