The three knight classes and Ayaka went to their final battle against Manaka, Servant Beast, and the fallen 6 Servants from the Previous War. Near the end of the battle, Ayaka went through an "Awakening" (unleashing the holy relic sealed by her father) to aid her Servants a way to eliminate the Beast, rising up the Master Rank from Princes to Seraphim, causing her sister to demote to Princes.
Manaka and the Beast, along the Servants of the Previous Grail, were finally killed, and the Grail was destroyed once and for all. Only Ayaka and the Skyscraper President were the last surviving Masters of the Grail War. The story ends with these two scenarios:
- Scenario A (Based on Fate): They fade away after the war, returning to the Throne of Heroes (or for Saber's case, to Avalon) after Saber confessed his feelings for Ayaka.
- Scenario B (Based on the True End of Heaven's Feel): Under some circumstances, they were able to maintain they existence after the Grail's destruction that they all decided to stay with Ayaka, and thus will begin the beautiful reverse harem triangle we all know and love.
He and Ayaka were founded and rescued by Members of the Mage Association or the Holy Church. Though Ayaka is recovering, her father is far from being saved. In the hospital (or any place they were sent to be restored), as he slowly dies in front of the restored Ayaka, he informed her to be prepared for the upcoming Grail War, and later apologizes for not being a great father to her (as he focused more on teaching Manaka, his heir). As he believed his death is a punishment for not caring Ayaka, and tells her that it's alright for her to hate him.
Ayaka, tearfully cried out that he's wrong, she still loved him and beg him not to leave her, as he's the only family she had left now. Her father, express remorse for leaving his last daughter alone, but was able to return his love to her one last time, and reassured her that she'll be alright, as he know that Saber will come back, and he prayed that Saber will always protect her at all cost, to keep her safe throughout the end of the war. He then passed away, and seeing him die in front of her made the young Ayaka traumatized, which made her not wanting to participate in the Grail War and to see another life taken in front of her eyes (especially when she had a difficult time to sacrifice her pigeons).
- Confirmed. It's mentioned in the prequel novels that their mother is in fact British.
- and for something epic, in the Final Battle, Ayaka would go through her Awakening, creating a large cirle beneath her that represents the Round Table, and not only it help Saber unleashing Excalibur's true power/breaking all of Excalibur's constraints, but she can summoned the Knights of the Round Table to aid her three Servants to defeat the Beast.
- it could be like how Sunannomon in digimon preformed his last attack. The in a humanoid abomination form rushes fowerd pushing Gilgamesh and Cu away and impales Saber. Saber looks him in the eye and sayes "this end today" he raises Excailbur and swings The Ghosts of the Knights all preform a attack (probley there noble phantasms) before Excailbur swings done.
- While the above two would be really awesome, it's doubtful. Avalon was a central part of the original Fate's design. So it would be only natural that Ayaka still has it here much like how Shirou had it inside him for the majority of Fate/stay night. That, and it's stated to be a Holy Relic, and the only thing that comes to mind would be Avalon.
- It's probably the relic that Manaka used as well, as Ayaka is stated to have summoned Saber because of the relic inside her. So it has to be something that's connected to King Arthur closely for that to happen. The Round Table doesn't really work as it could bring about any of the 13 knights who served the former.
- That said, there is still a chance of Avalon being changed up since Proto-Rider was changed from Theseus to Perseus. But again, doubtful. Especially given the fact that Ayaka was stabbed by Proto-Lancer just before she summoned Proto-Saber, but the moment afterwards, there's not even a wound. Granted this could attributed to the animation itself rather than story, but the fact that their's an audible stabbing sound kinda puts a dent in that.
- Jossed. Fragments reveals that Manaka used Avalon (though unnamed unlike FSN) as her catalyst to summon Saber, so it's likely the same catalyst that allowed Ayaka to summon Saber eight years later.
- Lancer: Heavily implied to be Brynhildr = Spearwoman that wears an exotic armor, carries small red bottle and her body wrapped by fire magic.
- Confirmed
- Caster◊: Either Faust or Mephistopheles = one act mentioned that Caster wears a black mantle and also a Demon look-alike.
- Jossed, as his identity is revealed to be Paracelsus in the Second Act.
- Archer: Possibly Oddyseus or a Pandavan hero. His archery is compared to Sir Tristan's, and his stronger shots can shave parts of mountains off.
- Jossed. He's Arash, a hero of Iranian mythology
- Rider◊: All but directly stated to be Ramesses II, as he was alive in Moses' time, had Nefertari as his wife and has a Noble Phantasm called Ramesseum Tentyris. He also tells others to call him Ozymandias, the Greek name for Ramesses II.
- Berserker: A legendary figure that associated with the Werewolf Legend = due to having a timed transformation, that this Servant will go to its mad enhancement (howling) at the presence of the moon.
- Jossed. He's Dr. Jekyll and Mr. Hyde
- Assassin: Heavily implied to be the Female Prototype-version of Hassan-I Sabbah = has grey-blue skin and wear skull mask, and can transform into cat.
- Confirmed.
- While that would make sense, there's hole in that logic. If his contract is the same as Artoria's, then giving up on obtaining the grail and having his wish fulfilled would erase it, removing his ability to be summoned as a Servant as he'll go towards Avalon instead of the Throne of Heroes once he disappears. This is due to the fact the King Arthur is the "Once and Future King", considered to be still alive as a person and is only resting in Avalon, waiting for the day his country needs him again.
- Except that as Fragments reveals, Arthur's wish is not to have someone replace him. Rather, it's to create an eternal kingdom of peace where the people no longer have to suffer.
