Fate: Avenger

London, one year after the end of the Holy Grail War.
Yuto Emiya has finally buried his swords, Servants and his past. He has a normal life: university, a job in a bookshop, fish and chips with his girlfriend, and the promise he made to Mordred to "live as a human being."
Until one rainy evening, six impossible figures appear in front of the London Eye.
Red and gold armour that flies.
A shield with star.
A hammer that summons lightning.
A green giant that shakes the ground.
They are not Servants.
They are the Avengers. And they have just fallen into his world.
The Clock Tower has already given the order: immediate containment... or elimination.
Yuto tightens the strap of his rucksack.
His normal life has just ended.
Again.
