Fate as a Servant FaaS

Is it not enough being reborn in the Nasuverse? Is it not enough being a servant? I can deal with all this, but why do I have to be Aqua?! She shouldn't even be from this verse so why?!?!


Mc won't be as stupid as Aqua just in case. There is smut.
I know what you are thinking, not useless Aqua + smut? Absolute perfection. Well... you are absolutely right.
Slightly AU, changes will be explained.

Neither the images nor the fate verse belong to me. Each belong to their respective authors.
