Fan CastingFate/Stay Night(Season 2 of Disney+ live action adaptation)

Zouken Matou and True Assassin are running wild. So is the mysterious shadow cuasing terror to Mages, Servants, and regular humans alike. Little does Shirou know that the host of the shadow is none other that his friend, Sakura Matou. Beyond the monster she is hiding, Sakura also hides information unique to this live action remake. She knows why our heroes have encountered challenges from the three routes of Fate. This is only one out of many universes where Shirou joins the Holy Grail War. This Sakura's dark powers allow her to see how this universe is different and the points of divergence that led to events like Rin, Saber, and Shriou having a threesome to restore Saber's mana, why Archer hates Shirou, and why Sakura will not end up with Shirou in the end of the war.
