Arc 7The God Slayer’s Challenge
Arthur ended the Fourth Holy Grail War, brought Saber to Avalon, and entered a world where he could fight Heretic Gods. After defeating Perseus, Melqart, and Verethragna, he gained new Authorities and powers, while Erica and Saber began disputing who should serve as his knight.
- The King of Conquerors questioned Saber’s wish to change Britain’s fate, then summoned his army to defeat the Assassins as Arthur and Gilgamesh prepared for their own rivalry.
- Arthur made a deal with Kariya Matou, rescued Sakura Matou from Zolgen Makiri, and killed Zolgen after obtaining his books on Reality Marbles.
- Arthur defeated Iskandar with Rhongomyniad and fought Gilgamesh with Excalibur, Ea, and his Reality Marble before sensing the Holy Grail’s corrupted mud at the church.
- Arthur fought Saber over their competing wishes, then watched the Black Mud engulf Fuyuki and left with Sakura after the system declared him the war’s victor.
- Arthur used Avalon to stabilize Shirou, returned to Avalon, and summoned Saber as his Servant before traveling to Naples and defeating Salvatore Doni in a duel.
- Arthur released the divine dragon from the Hera Pillar, killed Perseus with Ea, and became a God Slayer after Pandora’s reincarnation ritual took effect.
- Arthur killed the divine boar and defeated Melqart, gaining the Authority of Sky, then fought Verethragna and defeated him with the Golden Sword and Warrior incarnation.
- Erica pledged herself to Arthur as a knight, but Saber returned and challenged Erica’s claim by insisting Arthur did not need another knight.
