In a different timeline which was pretty different from the other Shirou who was supposed to summoned Saber servant Artoria Pendragon

He instead summoned a Berseker servant named Morgan Le Fay

They both participated in the grail war but due to an anomaly which made the grail war for some reason being nullified or postponed

And most of them survived servants are still here and some have summoned another servant making a total abnormal grail war if the war is continued

But Shirou somehow was able to hit off with Morgan and then that is how Y/n Le Fay Emiya born

Shirou after graduating from high school opened a family restaurant and usually will go work from morning to afternoon

And Morgan who is at home will Look after Y/n

Morgan was a really kind and caring mother

Although she may time to time curse something or say some cursing words

And at one point she even teaches Y/n a curse word

Morgan: " Look Shirou Y/n can say some pretty good words "

Shirou: " Really what's that? "

Morgan: " Okay Y/n say what you just say to your mother "

Y/n: " Fa-fa "

Shirou: " Oooooh "

Shirou was waiting full of anticipation on what his son will say but...

Y/n: " Fakyu Atoia "

Shirou: *Petrified*

Morgan: " Good job Y/n, we should practice how to say r next time "

Y/n was happy being praised by his Mother

Shirou: " ... I think I should call Sakura to look over Y/n "

Morgan: " What!? Don't you dare call that cursed woman here! or I will kill you "

Shirou: " You will also gone if you do that "

Morgan: " I just need to kidnap someone with High mana and make a forced contract cause I can't leave Y/n yet "

Shirou: " ... Either way I'm gonna go and make some dinner "

And when Y/n is 6 years old
