The End Is Near, Rebuild the Past and Look to the Future!

Make a pact with someone from the future, return to the past, and change the future!

This is the most important turning point in my life: the moment I gained the world's most extraordinary power.

For the sake of the world, I would gladly lay down my life.

"Did I succeed? Will I... succeed?"

This is a question no one can answer, and one that has no answer.
