Arachne

Arachne is a weaving-type monster serving under the secret society Akastia, where she focuses on technical support and design work related to monster development. Gifted with remarkable creativity and a seamstress-like precision in her craft, she tends to remain within her own lair and speaks very little, yet her unwavering professionalism makes her an indispensable behind-the-scenes contributor to Kuroitsu-san's development endeavors.
