This three-piece special brings an end to the anime adaptation of the Fate/Extra video game, Fate/Extra: Last Encore. Hakuno and Nero were able to defend against the countless clones of Rin and Rani and managed to ascend to the seventh floor of the Holy Grail War together with Rin, whom they newly awakened from her century-long slumber. Shortly after arriving on the seventh floor, however, they are greeted by an old acquaintence of Nero’s—a Servant she remembers all too well: Sir Gawain; Knight of the Sun and King Arthur’s nephew. He tells them that his Lord, Leonardo Harwey, has fallen into a long sleep after having been defeated by the real Hakuno Kishinami 1000 years ago. Nevertheless, to continue towards their goal, Nero, Hakuno, and Rin absolutely must defeat Leo, lest they be stuck on the seventh floor.
Gawain decides to wake his King Leo from his slumber and now Nero and Hakuno have to face their most powerful opponent yet: the strongest Master and his Servant—himself being the strongest of the Knights of the Round Table. Can they prevail against such a foe? And even if they make it, do they have the strength to go on and face off against Twice H. Pieceman?
