After defeating the Floor Masters on the six previous levels, Hakuno Kishinami and Saber reach the top floor of the Moon Cell. Their opponent is Leonardo B. Harwey, known as the strongest Master in history and a fan favorite following his victory. As they enter a field of flowers among floating islands, they encounter a hooded man tending to the blossoms. This cloaked figure reveals himself as Prince Gawain: the Platinum Saber and Knight of the Round Table. However, when Gawain states that he has no interest in fighting, the group discusses the endless possibilities for the Holy Grail with Hakuno determined to restore the Moon Cell to its original form. The conversation ends with a distant clangor echoing through the skies. Gawain informs them that time is running out and beckons them towards the final battleground, where Saber will once again duel another Saber to determine mankind's future.
