Fate/Hollow Ataraxia Remastered

Six months have passed since Shirou Emiya emerged victorious from the Fifth Holy Grail War. Life in Fuyuki has returned to something resembling normalcy. Then Bazett Fraga McRemitz, Seal Designation Enforcer from the Mage's Association and former Master in the War, awakens in a desolate mansion on the city's outskirts. A shadow called Avenger — a Servant of a class that never existed in the Fifth War — greets her with a proposition to continue the Holy Grail War for her sake. Shirou steps back onto the stage. Four days of destiny await.
