What if, instead of Summoning just Saber(Artoria), Shirou Summoned Saber(Artoria), Assassin of Black(Jack The Ripper), and Caster(Irisviel). How will Shirou's life be like with a Saber, his Kouhai(Sakura, as well as Rider(Medusa), and Resident Tsundere(Rin) as love interests, a Self proclaiming daughter(Jack The Ripper) that calls him Mommy, and a the extended Family his father never told him about(mother Irisviel and big sister Illya). And more importantly, HOW IS HE SUPPORTING THEM!?!

(-Irisviel forced a miracle to happen and gave Shirou the Magical Circuits needed to easily support even all 7 of the heroic spirits.
