Replacements [c.s.]

[plot w/some yaoi]

Two boys, each chosen to train under one of the two most powerful beings in existence in order to fill their role (even immortals would like to retire).
Jun will replace God.
Rin will replace Satan.

Jun is cute, clumsy, and big-hearted, bordering on naïve, which attracts God at first.
Rin is cold, womanizing, and cruel, and he excels at abusing his power; he's more of a devil than Satan's own sons.

But when Jun turns out to have a dark past and darker secrets, what will God do with his apprentice?
And when Rin is discovered to have a soft spot for animals and a love of all things cute, how will Satan take it?

As it is later found out, the boys know each other from school, and even stranger, both harbor secret feelings for the other, the likes of which they haven't ever dared to contemplate. Worse still is when God and Satan find them experimenting with... things, even if the two swear up and down that it's strictly business.

Everything is not as it seems.
