[Complete]
Shirou is the protagonist: Muramasa Shirou.
During the Third Holy Grail War, the intervention of the Millennium Tree from beyond caused the Holy Grail to shatter. The Einzberns suffered heavy losses, while the Tohsaka family barely survived. The old worm "died," and the Matou family abandoned their insect magecraft, returned to ordinary magecraft, and went back to their homeland.
Although the scattered fragments could no longer grant access to the Root, they could still bestow immortality, making them an irresistible temptation to mages. As a result, lesser wars over the Holy Grail fragments raged around the world.
In a secret chamber belonging to the Muramasa clan, several pregnant women were undergoing a certain magecraft ritual. Its purpose was to restore the glory of the Muramasa clan. Among the children born from the ritual was one named Shirou.
"I'm Muramasa Shirou. I like forging metal. My wish? It's not to become a hero of justice. I just want the people around me to be safe and well."
