The Fool Who Fell For God

(This story is heavily based off of attack on titan. However, many of the concepts are different, and it takes place in a completely different universe.)
(I also have a cover being drawn right now, so bear with me.)
Although he kept his faith, god never kept his faith back. Lucas watched the world he lived in get ripped to shreds, and watch himself slowly realize that everything he thought and believed in was a tragedy, and learns the truth of existence.
