Shina Dark fills that spot I think, does give another role to the devil tho

Not technically satan, but it involves religious stuff.

I like how they warped the Jesus Christ story in this manga. Very hilarious, though if you are like some people who get offended easily. This might not be your thing as the author warps the story around.

But for people like me who can read a story and not take it seriously, its one hilarious/fun read.

i am surprised nobody mentioned Devil and Devil yet

21st Century can be infered as the second coming of christ where it says the devil comes to earth and wins over almost all humans

Island..but its more of a buddaist / devil rather than

Superior - female devil who falls in love with the hero not sure if it fits into ur description

Disgaea!!! well not really

ill update if i remeber more :3

I can't believe Priest wasn't mentioned yet

Priest -[url]http://www.mangaupdates.com/series.html?id=1933[/url]

Summary - [url]http://en.wikipedia.org/wiki/Priest_(manhwa)[/url]

It's a bit gory, but the story is really intriguing and dark.
I hope this is the type of reading you were looking for.

Crimson Grave - nice if u like ecchi comedy type.

Devilman - gory and bloody, but this one is a must. Very, very good.

And as the others mentioned Majin Devil - It was also nice.

Beliefs are what divide people. Doubt unites them.

akuma na eros!!!!
that is, if you like smut 😁
