This is deffinetly a gold that in my point of view deserv to be in the same line with "I have a mansion...." in the ratings. The story is about the guy who for some reason awoken to the power of time manipulation and time travel. And he is deffinetly worthy of such power, as he understands how godly is his power and that he himself desrve to be a ruler of the world. It is a protogonist that seen so much that this world does not pose a chalenge to him. He will enslave and kill those that stand on his way, pulverise anyone that would disrespect him with no questions asked. He is not some pushover with no ambition like all MC's in Japanese issekai novels. Thats how a ruler should be. He is no hero but as he has seen destruction of galaxy and death of the humanity by their own hands (felt it even as his body was anigilated to atoms by atom bombs a hubdred or even thousand time until he learned how to use the power), he decide to save humanity from itself. And thats a story of how he does that. You believe the theory of conspirasy and world government? Well he is the one behind the worlds government!
