Arc 10The Six-Day Judgment
Messmer’s power and the Grand Duke’s fury brought a divine catastrophe to Fuyuki, killing several Servants and leaving the survivors trapped outside the Great Hollow. As Kayneth organized a plan to fight back, Shirou went searching for another Master and found a frightened girl at the Matou manor.
- Shirou became Cú Chulainn’s Master, while Vlad III fought Iskandar and Gilgamesh before Kiritsugu’s assault on Kayneth left Kayneth without his magecraft.
- Kayneth accepted the Grand Duke’s blood and became a Dead Apostle, while Messmer attacked Kirei and discovered that her power could identify and burn evil.
- The Grand Duke spread corruption through Fuyuki’s leylines and embraced heavenly fire, while Messmer’s flames grew into a world-threatening ritual.
- Sola helped Kayneth escape Kiritsugu, and Kayneth made Waver his heir before ordering Lancer out of the war and transferring the Grand Duke’s contract to Kirei.
- Cú Chulainn used Shirou’s Command Spells to fight at full strength and battled the Grand Duke, while Caren killed Kirei with help from a Hundred Faces substitute.
- Cú Chulainn, the Grand Duke, Kirei, and Gilgamesh died as Messmer’s flames overwhelmed the Great Hollow, and a voice declared that her domain would encompass the world in six days.
- The surviving Masters gathered to plan a counterattack, and Kayneth proposed accelerating a ritual to elevate Iskandar’s Spirit Origin with help from Kiritsugu, young Gilgamesh, Tokiomi, and Waver.
- After Proto Saber told Kiritsugu about another timeline, Kayneth sent Shirou to find the other Servant’s Master, and Shirou found a frightened girl with a glowing book at the Matou manor.
