Three sisters, Koyuki Mitsuya, Satsuki, and Rika, as the Aurora Sisters, continue to fight against Hell, who wants to make this world a land of the dead and rule it. The three sisters were once thought to have defeated Hel, but Hel was a double warrior, and Satsuki, who was captured in the battle at that time, had a seed of evil embedded in her body. Satsuki, whose evil seed has blossomed, is dominated by her body, and she becomes the Aurora Killer and attacks Rika. Koyuki transforms and rushes to save Rika, who is unable to resist and is tortured and captured, but is defeated by an attack by two of Hell's transformed beast god Fenrir and Aurora Killer... .
