POWER OF PRAYER (REQUEST) (Patreon)

The first request story of 2019 and the first story of the January batch! A story involving the twinning of Ritsuka into Saint Martha (with a mini da Vinci -> Tarrasque bit)! I had to play with the FGO timeline a bit, mainly because what is the timeline in PT2? So don't worry about it if it doesn't match up with canon all that much.
