Arc 31The Fifth Holy Grail War
Allen returned to Fuyuki for the Fifth Holy Grail War, where Sakura and the other Masters fought as old alliances and family plans resurfaced. The final battle began at Ryūdō Temple, leaving Red A dead, Shirou defeated, and Allen stepping onto the battlefield as Sakura froze Gilgamesh.
- After the Fourth War, Allen reunited Sakura with her family, prepared the next war, and summoned Artoria with Avalon as her knight.
- Sakura summoned Medusa, Rin summoned Gilgamesh, and Shirou summoned Red A as the Fifth Holy Grail War’s Masters gathered and clashed.
- Sakura and Medusa attacked Ryūdō Temple, killed Medea and Kuzuki Sōichirō, and later defeated Heracles while sparing Illya.
- Allen warned Illya that the Einzberns had lied about her fate, then helped Kiritsugu rescue her and transfer the Lesser Grail into Bazett.
- Cú Chulainn fought Gilgamesh and died after his final spear broke Red A’s defense, while Illya reunited with Kiritsugu and Irisviel.
- Rin, Shirou, and Red A prepared to fight Sakura and Medusa at Ryūdō Temple as Allen and Artoria watched with Bazett.
- Red A destroyed Medusa’s Pegasus with Unlimited Blade Works before Medusa petrified and shattered him, and Shirou collapsed while protecting Rin.
- Sakura repelled Gilgamesh’s Enuma Elish and froze him, while Allen removed the Lesser Grail from Bazett and entered the battlefield.
