Arc 3The Nameless King’s Gambit
Shirou transformed into the Nameless King and destroyed the Sea Monster, then forged alliances and forced Kenshinnes to withdraw from the Holy Grail War. After a dream brought him face to face with Morgan, he returned to the Einzbern household as Kiritsugu’s attack and the remaining Servants’ plans loomed.
- Diarmuid’s Geis transformed him into a boar-skinned Magical Beast, and Saber broke their alliance as Shirou agreed to face the Sea Monster.
- Shirou used Dead Count Shapeshifter to accelerate his body into the future, became the Nameless King, and destroyed the Sea Monster with the Blades of Chaos.
- Saber caught Shirou as he fell, and he recovered at Einzbern Castle before allying with Saber and Irisviel and revealing what he knew about the war.
- Shirou persuaded Waver, Rider, Saber, and Irisviel to help rescue Kenshinnes and Sola, then arranged for Saber to lure Lancer away while Waver confronted Kenshinnes at the Hyatt Hotel.
- Shirou tricked Kenshinnes into giving up the war by claiming Sola would die without an antidote, then revealed she had never been poisoned and Kenshinnes and Sola left for London.
- Emiya Kiritsugu ambushed Hundred-Faced Hassan on Fuyuki Bridge, while Shirou dreamed of Arthur’s doomed effort to reclaim Cornwall and met Morgan, who called him her little brother from the future.
- Shirou questioned Lady Avalon about the dream, then joined Saber and Irisviel at Einzbern Castle as they prepared to go shopping and gather information on Gilgamesh and Iskandar.
