So I know this might be overruled but when I played with Sparda during Legendary Dark Knight Mode, I noticed he had a thick, singular red gem merged to the center of his back via Air Raid. I wondered if you would explain to me what this thing on his back is, or if it was intended to be part of his demon form design. I don't know if you and the admin's might not noticed this but I did XD. Anyways, just thought you'd like to know what I noticed during gameplay. I can explain to you how I found it if you'd like.
