According to my Beast Heart Suit, this was not permanent. While I had gained an intense amount of power from my Chaotic Arsenal, it was burning through my mana at an alarming rate.
Akasha, still smiling, started to spin the bladed end of her chain. "A new form? You look more like a demon than a human, but I can feel your mana going down. How long do you think that you can keep this-"
My body moved on its own, and Akasha just had time to block my strike with the scythe. Her body, for the first time in this fight, was sent hurtling back into the black knights. I tried to be surprised, but my body kept moving and I reached Akasha in the blink of an eye.
