Over 200 years has passed since the event and I'm trying to find the answer to how this place came to be. I know it's not going to be easy and you can guarantee I'm going to fall into some unwanted predicaments. My goal: return it to the time before even if it takes destroying this world. To do that i think i have to find the one who cursed me and stole my memories... What i truly am, I'm yet to find out, and how I plunge the world into its current state. Author's note: I know my synopsis sucks but pls bear with me.
