In the ruins of a shattered Tokyo, Ayane presses forward as waves of hellspawn close in from every shadow. Her path brings her face to face with the twisted remnants of her own clan, whose corrupted strength now serves an ancient rite. Each clash tests both her blade and her resolve, drawing her deeper into the darkness that once claimed her sisters. The looming ritual threatens to awaken a power that could bind the last free kunoichi to a fate beyond redemption.
