Fate/strange Fake S01 E07 Back from Twilight, the God Is Come

"This is a Holy Grail War covered in lies."

Prior to the battle between Saber and Lancer, Halri Vorzak, a girl who harbors deep hatred for the world of magecraft, summons a Servant of her own. However, what answers her call is an utterly uncontrollable and aberrant Heroic Spirit. As its claws tear through her abdomen, her life begins to trickle away until a lone homunculus reaches out to grasp her dying hand.
