Arachne
Arachne (アラクネ, Arakune?), the leader of Arachnophobia, is the second major antagonist introduced in the series. She is a spider-like witch and the oldest of the Gorgon sisters besides Medusa and Shaula. Called a heretic among her kind, Arachne is responsible for creating the first demon weapons 800 years before the series by combining the souls of witches with humans and ordinary weapons. She went into hiding for 800 years after being betrayed by Medusa and hunted by Shinigami, scattering her body across the world in the form of countless black spiders and hiding her soul inside a golem. She returns to power after Asura awakens and begins spreading his madness wavelength across the world. Her plans involve capturing Asura and plunging the world into madness, though her means of achieving this goal differ between the plots of the manga and its anime adaptation. In the manga, Arachne discards her physical body and transforms her soul into an entity of pure madness, giving her the power necessary to control Asura. She is killed by Maka and Soul, who collect her soul and later use it to turn Soul into a death scythe, while Medusa possesses Arachne's lifeless body to use as her own. In the anime, Arachne succeeds in capturing Asura and uses a demon tool called the Morality Manipulation Machine to amplify his madness wavelength. However, Asura turns on her and eats her soul to increase his own strength even further.ep. 48 She is voiced by Michiko Neya in the Japanese version of the anime,ep. 27 and by Stephanie Young in the English dub.ep. 27
