Archer

Both of you quickly got up. However, Rin fell on her knee one second after she tried to stand.

You quickly helped her: "Are you fine?"

"My legs are still numb. Maybe we shouldn't do it so hard."

Seeing your guilty look, Rin laughed: "Don't worry, I just tease you. Healing this kind of sickness is easy for a Magus like me."

She walked towards the Servant, who wore a red coat and a black armor: "I'm your Master. Here we form a contract. My child, do you want to fight alongside with me in the sacred Holy Grail War?"

The girl kneed before Rin: "Yes, Master."

A mark appeared on Rin's abdomen, at the position of her womb. She looked at it and sighed: "You're Archer. I hoped that I can summon a Saber."

Then she turned to you: "You have already repaid me. Now you're free to go."

You replied: "You're carrying my child right now. How can I leave you alone while knowing you have to enter a war?"

Rin hugged you and placed a kiss on your lips: "I know you won't abandon me. My love, let's marry after we win this war."
