One year has passed since Emiya Shirou has awakened in another world after the Ainsworth's holy grail war. A world where the era of mystery has ended and in its place the new era of soul. Unable to find his sister within this new world, he turns his eyes once more onto the tale of a miracle, the Moon holy grail war.

He has thrown away his past ideals and yet fate seems to hold other ideas. Waking up from a coffin, Shirou would soon come to face with his past ideals in the form of an organisation called Chaldea.
