Shirou raised by the tohsakas

Background: During the 4th holy Grail tokiomi tohsakas was worried.The way the Grail was,with the servant he summoned he couldn't lose.But there's always the smallest possibility,so he needed to make sure that the tohsaka family would continue past his daughters and he was desperate so when he found a family with a child with 27 high quality circuits he had to do what he had to do.That involved hypnotising the family to let him have the boy.This was Shirou muramasa,now tohsaka.He would train the boy in magecraft and by some miracle he had happen to be an incarnation of the concept blade.With this he had to get jewels in the shapes of swords but after so the boy picked it up like a fish to water.The boy even asked kirei for some martial arts lessons,he even managed to get on Gilgamesh's good side granting him the first ever azoth sword.
Shirou tohsakas would grow up to be a skilled mage,while he doesn't have the family crest he got to keep his adopted fathers staff and with his status of being an incarnation he could perform all sorts of magecraft as long as they were in the shape of a blade weapon.
