Fate/Stay Night: [Remnant of Lost World]

There is a girl.
A girl that is a quite talented magus.
And from what is, the enraged giant from Greece turned her to what "was".
The girl died without being able to change her future.
There once was a girl.
A girl that fought for her destiny to no avail.
And died without anyone remembering her.

There once was a boy.
A boy who sacrificed all he was to save what remained of his world.
He died alone, losing himself in the darkness of his talent.
There is a boy.
One who is not from this time, and that is nearly unmatched in magic.
He heard the plead of a dying girl who, like him, would be forgotten.
With a heavy sigh and a spell cast, he changed the grim future that awaited the girl, and in the chaos, he found a partner that, in a sense, was the same as him.

There is a master with her servant.
A seemingly unlikely pair that found themselves in the middle of a war.
With unwavering determination, sharp wits and powerful spells, they walk towards the future that should not be.
And yet, they shall make it so, putting back together the Remnants of a Lost World.
