I, Matou Shinji, just turned six this year, and lately I've been having strange dreams every day.
A man named Ash slays countless mighty Lords of Cinder, turns their souls into fuel, fulfills the great mission of linking the fire, and saves the world.
A silver-haired man called a Witcher slays monsters along the way, all to find his apprentice.
A blue-clad man in pursuit of power unleashes a bloody rampage for the sake of strength and fights his own younger brother. In the end, the two join forces to resolve the crisis.
Stories that are grand and stirring, full of twists and turns, or simply beyond one's control all appear in his dreams.
And finally!
He dreams of the Fifth Holy Grail War, and of the loathsome "self" he sees in that war: Matou Shinji, twisted to the extreme, both insecure and arrogant!
And of his abused younger sister... and the "self" she eventually kills.
No!
I absolutely refuse to let that future happen!
As he stands there in shock, he sees a black-haired girl in the hall. His father, Matou Tsuruya, says, "Shinji, come welcome your little sister, Matou Sakura!"
At that moment, Matou Shinji knows: Matou Sakura will be thrown into the worm pit tonight!
He's decided to be a filial grandson and a benevolent grandfather!
