An Epic of a Golden Gamer (AU Gilgamesh)

A Nasuverse fanatic was born with an underpowered Gamer system in Ancient Babylonia...as none other than the gold demigod. His end-goal? Make Lancer Artoria his waifu. His inner Gil definitely approves...Misunderstandings and Bullshiting are necessary sacrifices. Now, if only he could stay alive... (Semi-Gamer, eventual Fourth Grail War, diverged timeline, System is SUS)
