Satan was bored of hell,all the tourture,thieves,and just imprisoning those who did wrongs gets boring after millenias so one day he went up to earth to find something interesting to do.

And that's when the two met and came upon a deal of sorts,Satan would break Archer's deal with Alaya in exchange Archer had to become the new Satan and rule hell.Archer finding just imprisoning evil doers better than killing everyone who was good and bad in an area took the deal.

I am the bone of my sword
Steel is my body
Hellfire my blood
I have created over a thousand blades
Unaware of heaven
Nor aware of hell
Have withstood countless battles in the search of hope
Yet ending in a place where it doesn't exist
I have no regrets for this was th only path
A path called
Hell's Unlimited Blades.
