Arachnophobia (蜘蛛恐怖症(アラクノフォビア), Arakunofobia) was a giant organization founded and headed by the Witch, Arachne Gorgon.[2]


Lost Island Incident

Eight hundred years ago as the head of Arachnophobia, Arachne stole the blueprints from the Book of Eibon containing information. She then baited Death to Lost Island with them in hopes of blowing up the facility to cover up Eibon's most powerful Demon Tool he created, "BREW", for her to reclaim at a later time and to hide it from Death.[3]

Creation of the Demon Weapons

Having gotten a hold of the blueprints to creating the Demon Weapons from the Book of Eibon,[4] the organization assisted Arachne in creating the Demon Weapons and manufacturing them in vast quantities,[5] killing witches and sacrificing their souls to create them.[6] As a result, it caused her to be hunted by the God of Death himself and her fellow kind for her transgression against them. She was later defeated by Death and forced to split her body and place her soul in the Oldest Golem, with it being guarded by her henchman Giriko.[7]


After disappearing and faking her death for eight hundred years, she is revived and the organization in which she spent eight hundred years secretly expanding makes itself known once again.[8]

  • "Arachnophobia" is a Greek word, literally translating to "fear of spiders". This seems fitting, as the entire organization's insignia vaguely resembles a spider. Also, its head is a spider themed witch.
