An idea came to mind after looking at at the Shirou(Miyu's brother) wiki page and thinking about fanfiction. Like the ones where Naruto is Illya's Servant. Then it hit me why not put a Shirou (Miyu's brother) is summoned as Berserker by Illya. If EMIYA is suited for Berserker that this should work.
My body is made out of swords.
My blood is of iron and my heart of glass.
I have overcome countless battlefields.
Not even once retreating,
Not even once being victorious.
The orphan is alone again, striking diamond dust on a hill of swords.
But this life is not yet over.
This false body was still made of swords.
Things I would like to happen but you don't have to do
His wish is to keep his promise with his beloved little sister.
For him to have the Affection of the Holy Grail skill.(Miyu is his world's Holy Grail so why shouldn't he have that skill.)
For him to look like EMIYA(Archer) Stage 2 and wearing the clothes he had when he first installed the Archer Class Card.
For him to realize Archer's identity the moment he sees him.(Obviously he'll know but I just put it just in case.)
The main weapon he uses is 9 Lives Blade Works.
He can activate his Mad Enhancement by using or seeing certain words and things and vice versa or something like that. Like the Ainsworth or something.
Anyway that's all, those were recommendationsI had, but you don't have to do it. All I want is for Illya to summon Shirou(Miyu's brother) as Berserker that's all. He could also be summoned as Avenger if you want.
