Note: Please read the introduction for some popular science.
This is the magician-killer Emiya Kiritsugu who did not participate in the Fourth Holy Grail War.
He became what he was not supposed to be, the heroic spirit Emiya Kiritsugu, a scavenger-like existence.
During a mission sent by Inhibition, he encountered the Holy Grail of Black Mud, completed his incarnation, lost part of his memory, and came to another world.
The world is full of curses, and he was identified as being cursed by a special curse spirit by a guy who claimed to be the strongest spellcaster.
Kiritsugu, who was being watched tenderly by the special magical spirit Great Holy Grail Irisviel behind him, looked indifferent and raised his gun to kill the white-haired man.
PS: Second edit
Some friends mentioned the issue of age. In Fate, you can hardly tell your true age from your appearance. After all, the Holy Grail allows the servant to appear in the strongest form. Kiritsugu's strongest period was probably that of Koro-sensei
The Young Emperor and the Great Emperor, Young and Twinkle, cannot be divided into age groups. I am also bald myself. The reason why they are young is to make it easier to go to school. The wife herself also looks very girly, although she has a maternal nature.
Because a reader commented that the effect should be very good, so I might arrange for Illya to appear for a while, and then go offline for a while, but it will not be the way of death. However, if there are more followers, it will be impossible. Don't bring children with you on your honeymoon.
There is no CP because Kiritsugu and his wife in this line have not met each other, but the wife who is the Holy Grail still cares about Kiritsugu's father after returning to her true form.
In this plot, Kiritsugu can't see his wife at the beginning because he can't hear the whispers in his ears that he doesn't know what to say (skill, introduced in Favor of the Great Holy Grail.)
He looks like a teenager, with white hair and black skin, because that's what Fate officials gave him. He will kill enemies without hesitation for the sake of world peace.
Because it does not belong to romance and beauty by definition, there is no CP, but the only ones who make Kiritsugu afraid of redemption are Madam and the others, although Kiritsugu in this line did not meet Madam.
It's late, but it will be updated every now and then. I'm sorry, everyone. I am a dove, I admit it.
Purpose: The Emiya family is full of heroes
