Fate/Extra: Last Encore - Illustrias Geocentric Theory

After overcoming the Floor Masters, Hakuno and Saber arrive at the Moon Cell's summit, poised to confront Leonardo B. Harwey. Before the final battle, they find themselves in a field of flowers among floating isles, where they meet a hooded figure. This figure is revealed to be Prince Gawain, the Platinum Saber. Gawain, uninterested in fighting, engages Hakuno, Saber, and Rin Toosaka in a discussion about the Holy Grail's infinite possibilities, with Hakuno determined to restore the Moon Cell. A distant clang signals the urgency of their situation. Gawain, aware of its meaning, informs them their time is limited and guides them toward the final battleground, where the two Sabers will clash to determine humanity's destiny.
