Hahah. . . .I see you prefer the characters I do :P

Hmmmmmmmmmmmmm. . . . . . .Maybe I should take TShara-chan's advice and make a more streamlined thread so people don't have to shlog through a lot of reading to hunt down pairings they like. . . . .

*Stares at selections* Well, since I cam up with them, I love all of them. A few of them we can't do because of conflicting preference(I have a very strong idea on who/what Death is that never seems to coincide with other people's ideas, and stuff like that) sooooo. . . Hmmmm. . . .

-God x Mortal
-Accidental Hero x Fated Protector(If I can be Protector)
-A creature is lurking through the streets at night, killing at random. A seasoned cop is hot on it's trail having tracked it across country. A talented young officer is assigned to the case, their keen eyes and powers of observation helping to point the cops in the right direction. The veterann at first takes issue with being assigned a greeny, but the vet soon starts to realize that it's more than natural talent guiding this young one. The newbie has a gift, and it's time to give it a workout.

Any of those three would work, however since I think you said earth would be easiest, then I think the third one is closest to that, though the second one could be worked on earth too. . . .
