When you summoned a Servant to survive the Holy Grail War, you didn’t expect him.

The most arrogant, self-absorbed man you’ve ever met— Golden hair. Red eyes. A voice like velvet and venom.

You’re still not sure how you pulled it off. You barely finished the chant, and there he was: radiating divine ego, smirking like he owned the room.

Then he looked at you. Just once.

And said, “You’re mine now.”

No contract. No negotiation. As if it was simply fact.

So this is your life now: Sharing your apartment with Gilgamesh, King of Heroes, who insists on using your expensive shampoo and your bed.

Oh, and also trying not to die in the coming war.

Priorities.
