Fate/Demi-Servant

What happens when there's another person besides Mash who becomes a Demi-Servant? And that contractor is from Gilgamesh of all Heroic Spirits? You get this!

There will be SMITE references for Gilgamesh/MC, considering I will be using an original NP since Enuma Elish will be later down the story.

[Before we begin, this story is an experiment! My knowledge of Fate is limited. However, as I write this story, I'm reading Light Novels and FGO Manga and playing FGO. So don't expect this story to be anything special. After reading a lot of Fate fanfics, I had this idea, but I was ultimately disappointed by the lack of Demi-Servant MCs.]

[Like most other Fate Fanfics, Harem is included, but probably no smut unless I feel it's appropriate!]

I hope that this will get people to try this rare trope out!
