Blazing Kurogane-Kai is created in the final battle when Tomoharu called on Kanade and Persephone to help him after Kanade stated her reason for fighting. Persephone attached to Kurogane Kai's back and became a pair of flaming wings. The combination also turned Kurogane Kai's armor black and the trim a fiery orange color. Kurogane Kai gained the ability to fly and use of Kanade's demonic ability, the Engetsu (Flaming Sword) as Blazing Kurogane Kai's weapon. Blazing Kurogane Kai uses two-sword style similar to Aki's two-sword style. Also, it is shown that Aki's spirit controlled Blazing Kurogane helping Tomoharu defeat Hagane and President Kagakari. It has been shown that Blazing Kurogane has power superior to Hagane when Tomoharu asked for Kanade and Persephones magic.
