One day, Robin gifts the protagonist a Holy Grail that grants wishes, but it's just an ordinary ornament with neutralized power. Old Otie, the founder of Penacony, puts the Holy Grail up as a prize and plans a competition. He intends to promote the Dreamscape business by summoning legends from history to fight.

IPC representative Scott harbors a grudge against the protagonist and invites the 'Nameless' for revenge. The protagonist participates in the Holy Grail War with Pom-Pom, Boothill, and Aventurine. During the summoning ritual, the protagonist fails to summon a Servant, and Scott provokes them but is defeated and runs away. Boothill's Servant Lancer attacks the protagonist, but the protagonist's Servant Saber appears and saves them.

Saber introduces herself as Artoria, the King of Knights of Camelot. Boothill and Aventurine talk with Archer and confirm that Archer is not related to Penacony's history. Lancer reveals that there are three Servants from other worlds, realizing that this Holy Grail War is different from the usual ones.

Robin is with her Servant Caster (Miss Note), and Miss Note promises Robin victory. Robin says she invited the protagonist because she wants to end the war. Miss Note and Saber try to fight, but Robin and the protagonist stop them. Miss Note asks about Saber's past, and Saber explains that she is a hero from another world. Miss Note is puzzled by her weakness, and Robin suspects Old Otie's intentions. Boothill invites the protagonist to the Clockie Studio Theme Park.

While Boothill, Aventurine, and Archer are waiting, Scott and Grady (disguised as Assassin) appear. Assassin traps everyone in a 'Silent Horror Movie' with his unique ability. Aventurine, Archer, Saber, and the protagonist reunite, defeat Scott, and try to find Assassin's main body to destroy his ability. They meet Robin and Miss Note, fight Scott again and win, but Grady keeps changing the scene, causing confusion. Archer destroys the director's lens, ending the situation.

Grady reveals his past and his dream of becoming a great director. Aventurine asks about Old Otie's plan, and Grady suggests asking directly at the Grand Theater. Old Otie waits with Lancer and calls Miss Note to face Lancer. It is revealed that Miss Note is Asna, the founder of the Iris family and a famous singer. Over time, her fame disappeared and she was forgotten. Consumed by anger, she tries to trap everyone in dream bubbles to erase their past and identity.

The protagonist wakes up in Britain in Saber's dream. Saber reminisces about her past as the ruler of Britain and talks about Merlin. She drew the Holy Sword and became king, but the kingdom collapsed and allies turned their backs. She decides to seek the Holy Grail to change her past choices. Miss Note appears and shows the protagonist an illusion of what it would be like if they were an ordinary researcher instead of becoming a 'Nameless'. She shows an illusion of Dan Heng, March 7th, and Welt returning to their respective lives. Encouraged by Saber, the protagonist realizes they have no regrets about becoming a 'Nameless' and shatters the illusion.

Miss Note admits defeat and asks Robin to execute her. Robin, as Asna's junior, refuses her request and uses a Command Spell to free Miss Note as a human, not as a Servant.

Everyone gathers again, and Old Otie reveals his intention to replace the failed Charmony Festival with the Holy Grail War. He believes the Holy Grail War will entertain Penacony. Obsessed with growth, he becomes a Berserker-class Servant himself to stop the protagonist.

After Old Otie is defeated, the illusion of the Holy Grail collapses. The Servants return to their respective worlds, and Saber encourages the protagonist to keep moving forward.

Pom-Pom summons Misha, a Rider-class Servant who is Misha's childhood self. They spend time together, and Pom-Pom tells Misha about the 'Nameless' journey. Misha disappears with the power of the Holy Grail. Robin gives the protagonist the Holy Grail as an apology gift, and the protagonist finds a note from Sampo. The twist is revealed that Sampo was the one who sold the Holy Grail and war idea to Old Otie.

The video ends, anticipating the next story.
