The End of Gotham - Confessions

The end of the world is coming that no one could have predicted. When human beings turned into zombies and swallowed the one they loved most regardless of their past feelings, they realized that this was the beginning of a catastrophe... Survival has become extremely difficult, so no one digs into the source of the disaster. And our Robin will tell you the truth he knows. But is this so-called "reality" the "truth"? Or is there another hidden story, just one person's one-sided words? (PS: This story is narrated in the form of a diary before the end of the world. If you are a first-person speaker, be careful! There will be OOC, so be careful!) Concept: People are never omnipotent
