Basically the show is about The God Of Conquest, Keima. He knows how to swoon the heart of any woman regardless of personality, scenario, and difficulties....in the 2D world.
You see Kami-sama is an otaku who thinks all 3D women are Pig Disgusting.
Then one day, Elsie, a devil, messages him to conquest the ultimate challenge.
Elsie of course, misunderstands that his title was for real girls. So now as a devil's contract, he must become a exorcist for spirits that cling to troubled girls, or face decapitation and Elsie's death.
So the GOD of Conquest must use the knowledge of the 2D WORLD that is ONLY he KNOWS to become the lover of girls IRL, only for them to completely forget him in the end, or die trying.
BADASS NERD USES PSP AND DATING SIM TACTICS TO GET ALL THE *****ES.
This show is SO good to people, that it has a 2nd season greenlit already.
