Mazaku was absorbed by the super-cursed warrior Kurayami in order to provide food for Shakou's revival as a dark demon god, but instead, he repelled Shakou's consciousness and took over his giant body. With a crimson body and long limbs, he engages in a fierce battle with the mobile warrior Daikou who appeared from the peak of the Akumuhaiki Yumeyama. The six demonic attack swords on his back fly out at Mazakuu's will and automatically attack the enemy. He has a double black star cannon that connects the black star cannons that Kurayami was equipped with. In addition, the special move Black Blade Demon Flame Slash, which is unleashed from the giant demonic sword Kuroha, is a terrifying technique that engulfs the enemy in dark flames and plunges them into a scorching hell.
