Will of the Demon King

Ok this is a Dark Keyblade that I made. The story behind it is that it is the blade of a demon king that was taken by a keyblader and used to kill him. The sword then turned into a Keyblade. The key has great strength and its final is call "Gate to Hell." The swords cuts open a gate and fores the enemy into a portal where they have to face a dark version of themselves who is 3 times their strength. Hope you like. Comment and all that jazz.
