Kami no Mizo Shiru Sekai (a.k.a THE WORLD GOD ONLY KNOWS)
My Favourite New Manga I picked up
Katsuragi Keima is known on the net as the god of getting the girls while in real life he’s known as otamegane and he hates all real girls. However he is approached by Elsee, a devil from hell, to help her in catching runaway spirits that hide in people. Apparently the spirits only hide in the hearts of girls and the only way to get the souls out is by making the girl fall in love so the spirit gets forced out. And he’s not allowed to fail or he will lose his head.
Kami no Mizo Shiru Sekai Link
It has A LOT of Visual novel (H-game) references, ef- Tsudere etc.... don't worry it's not a H-manga, it's very interesting, if you don't like the manga after the 1st chapters which is a good 30-50 pages then drop it.
For everyone else you probably can't get enough of this, ENJOY!
