"Darkness took everything from me, so I have to become darkness to take them back."

Natasha Walker is a general and president who served her country which was the last human civilization that exists in an apocalyptic world because to an endless war against the shadows. After the death of her son, she was swallowed by darkness. Her wish was simple but fate is unfair. Fortunately, a cracked-headed God gave her a chance to make that wish come true in one condition. Her mission is to entertain him through surviving into a game-like fantasy world as a shadow but she's not the only cheater in there.
