You know, I bet some people wonder where 666 was sealed by God. The Beast recorded in the Apocalypse refers to it as "out of the sea" so 666 was possibly sealed in the depths of the ocean to prevent anyone from ever awakening it.

I also read someone said that the reason why God created Sacred Gears and other stuff was to stop 666 should he be awakened into the modern world. Do you guys also think of that theory?
