In an obscure world gripped by terror, nightmares have come to life. Driven by the sole desire to eliminate their hosts, these monsters have become a plague to be eradicated. The Ordo-Sancti, a powerful religious group, has put the Weaver corps in charge of slaying the beasts. Arane Heos is a renowned member of the Weavers. As she battles the nightmares, she will have to deal with the growing turmoil within the Church and her caste, which now threatens the secret that involves her child.

In search of answers, Venus forces Arane to reveal her true nature. Unable to bring herself to disclose such a dark secret so easily, Arane, with help from Bastione, tells Venus the story of her birth, 19 years earlier. Meanwhile, acting under the orders of the mysterious Cardinal Lemegton, the paladins make their way to Heosias seemingly intent on bringing harm to Venus. With their relationship shaken by these nowrevealed secrets, how will Arane and Venus deal with this looming threat?

Now that Cardinal Lemegton has revealed his true face, a confrontation seems inevitable. Trapped, Venus and Bastione have no choice but to engage in bloody battle. Meanwhile, in the throes of grief, Arane is submerged by a wave of bloodlust in the heat of battle. But will this outlet be enough to soothe her heavy heart?

Reunited in battle, Solomon and Chevreul pose a terrible threat and have come one step closer to their ultimate goal of absorbing Venus' essence. And although Arane can count on Bastione and her daughter to help her, the merciless Cardinal wishes to exploit the Banshee's weaknesses in order to sow seeds of discord, both in Arane's mind and within our heroes' ranks. As this first arc in the war between monsters and men draws to a close, who will gain the upper hand?
