Yeah...a pretty almighty name but when I read it , it's pretty much the opposite of what I expected.
The Japanese name of the Manga is called "Kami Nomi Zo Shiru Sekai" ( Romanji )
In the Manga , the story is centered around an Otaku called Katsuguri Keima , who is obsessed and skilled with playing Visual Novels ( Supposedly , he only plays dating sims ) He was thus branded as the "Capturing God" due to his speed in completing such games and uploading his thoughts of them on the net.
One day , he received a mail which he considers an offence to his pride. Without hestitation , he accepted the offer in the mail and he summoned a Devil by the name Elsea. Apparently , he had unwittingly signed a contract to be the Devil's "Buddy". A human partner of a devil which is needed to fill the gap of the hearts of those who are possessed by spirits.
Essentially , spirits possess humans who have a gap in their hearts ( Not literally!! Emotionally!! ) and the only way to force them out is to replenish the "gap" within the heart. Due to Elsea's incompetence , and the price of the contract ( Death if you failed to fulfill the tasks ) , they resorted to "love".
Keima may be a Capturing God in video games , but he have absolutely no experience in dating real life women ( Not to mention , he is a typical Otaku who loves 2D girls and not the 3D ones ) , resenting the idea but due to the fact that his life is on the line , he accepted to help.
Oddly enough , he places his Dating Sim skills on the real life settings and it worked out surprisingly well. So as the story progresses , we see various girls ( The spirits only possess females since they can reincarnate as the female's child....a convenient setting I suppose. ) facing difficulties in life and how Keima gave them a hand-up ( Even if it isn't intentional ) via the usage of "love".
So essentially , this is a Harem Manga to the extreme.
Leading Characters :
Katsuragi Keima - Despite being an Otaku and being the most hated High School Student within the school , Keima is surprisingly intelligent. If he wants to, he can ace in every single test ( He actually scored a 100 for all subjects ) and he knows what to do in order to charm those who had been possessed by the spirits. His truly a human God....if he wasn't an Otaku :P
Elsea - A 3rd Clas* Devil ( A really low ranking Devil ) who used to be in charge of cleaning in Hell. However , she had received the opportunity to hunt for spirits and she became the partner of Keima. Elsea can be fairly air-headed and naive , not to mention that she can't cook any meals fitting for a human to eat. ( Their meals of Hell! ) She also enjoys sweeping... =.=
Overall :
Well , this Manga , is basicallya Harem. There is no fan-service but this Manga is stuffed with moe girls ( Each character have their own set of personalities and troubles , most of the girls are from the ages of 16 - 20 + , young girls around Keima's own age , there's even a student teacher come to think of it , annoyingly enough , the girls' memories were wiped of Keima the moment he finished his task )
Plot-wise , this is actually below average , this is a Manga focusing upon "mini-arcs" and most of the time , we only see Keima trying to charm the target girl in order to free her from the spirit that was possessing her. ( An average of 3 chapters per girl )
But the humor content , artwork and several other factors actually pretty much made up for it's fairly average storyline.
If your a romance fan...well , this wouldn't be your cup of tea. But for comedy , Harem and Slice-of-Life fans , this is a must read.
By the way...This isn't exactly a review :P It somehow ended up being a review o.0
