Tohsaka's secret job -FGO- (Patreon)

The story would be like this..

Tohsaka's resources are starting to scarce the further the Holy War goes -She is almost bankrupt-,in order to keep things flowing on and being able to obtain as many jewels for her magic to work,she ends up showing her body and selling erotic pictures to some rich kid infatuated with her ! Dont search logic just stare booty

Her magic is flawed with the jewels thingy,Gilgamesh would be best servant with his many treasures xD
