Fate/Extra: Last Encore - Illustrias Tendousetsu

Hakuno Kishinami, Saber, and Rin Toosaka arrive on the top floor of the Moon Cell after defeating the previous Floor Masters. Their opponent is Leonardo B. Harwey, the strongest Master in the Holy Grail War's history. They meet a hooded figure, Prince Gawain, who is tending to a field of flowers among floating isles. Gawain, revealed to be the Platinum Saber, declines to fight, and the discussion turns to the potential outcomes of the Holy Grail.
