The World God Only Knows: Chapter 1

The World God Only Know (WGOK) is about Katsuragi Keima, A.K.A  "The God of Conquests". He lives his life beating popular dating simulation games and winning the hearts of virtual girls. He's a lot like Furuya from Sankarea. Furuya is only attracted to zombie girls, as Keima is only attracted to virtual girls.

One day, after his online personality receives a message questioning his skills, he gets thrown into a contract with the devil. And if he breaks it, both he and the devil helping him, will have their head's chopped off...

His mission is to save all the "runaway spirits" with the help of a demon girl named Elsie. Since spirits seem to hide within the empty spaces of women's hearts, it's Keima's goal to fill them...And what better way to do that than with love? 

However, The God of Conquests is actually called otamegane in the real world, which pretty much means "gloomy geek with glasses". So now, the otamegane needs to use his virtual dating skills and apply them to the real world. And what better way to start than with the star of the track team? 

After cheering her on, "increasing his encounters", and eventually copying a confession from a video game he played, he managed to win her heart...and the demon within it. We also learn that he's one of those stereotypical nerds that turns into a bishounen once his glasses come off -_-. 

But after all is said and done and the demon is captured, it turns out that every memory of the girl's love is lost.

I expect the rest of the series will be rather repetitive, but since it's #2 on the most popular manga series, I'm willing to give it a shot. Its first episode gave me a good first impression!
