Vol. 4The King Comes Home
Shirou fought to stop Amakusa Shirou and Metatron from remaking humanity, then returned to Fuyuki and reunited with his family. He chose to protect Justiça as his familiar rather than begin another Holy Grail War or allow her to die.
- Mordred recognized Shirou as her father and agreed to protect Aika, while Shirou and his allies seized the Greater Grail and uncovered Amakusa Shirou’s plan to save humanity.
- Shirou formed a pact with Fiore and joined the fight against Caster’s regenerating Adam Kamon, asking Jeanne to replenish his mana so he could destroy it.
- Shirou died fighting Karna, rebuilt his body with Lady Avalon’s help, and defeated Karna with Unlimited Excalibur Works.
- He rescued poisoned Masters with Atalanta and learned that Manaka had taken another Holy Grail and likely entered the Floating Garden.
- After Aika’s death, Jeanne Metatron declared that humanity would be destroyed in seven days, and Shirou gathered allies to confront her.
- Metatron absorbed Shirou after surviving his attack, and he awoke in a strange space beside Jeanne frozen in an ice coffin.
- Shirou rejected Metatron’s refuge and helped defeat her before returning to Fuyuki and reuniting with his family.
- He chose to make Justiça his familiar and protect her instead of starting a Fifth Holy Grail War or sacrificing her to dismantle the Greater Grail.
