In a world where humans and demons coexist, a delicate balance is maintained by the Karas, powerful beings tasked with keeping the demons in check. For a long time, a young woman named Yurine and her servant, the Karas, have upheld this balance, allowing humans to live their lives without fear of demonic interference. However, as humans begin to forget and mock the existence of demons, an old Karas named Eko, disillusioned with humanity's arrogance, abandons his post and creates an army of mechanized demons, known as Mikura, to attack the human race. As Eko's actions threaten to disrupt the balance, a young man named Otoha inherits the powers of the Karas and joins Yurine to restore order. Meanwhile, a police officer named Sagisaka and his partner, Kure, investigate a series of murders committed by Eko's Mikura, as well as a rogue Mikura named Nue, unaware of the larger supernatural conflict unfolding around them. As the prophecy unfolds, Otoha must prove himself as a worthy Karas and prevent Eko's plans from coming to fruition, leading to a grave revelation that will affect the entire city.
