Emiya Shirou doesn't want to work overtime

This is just a story about a partner in justice.
The story of Emiya Shirou.
At a certain moment, at a certain point in time, a door that should not have appeared appeared in front of a man named Emiya Shirou.
He's just a magician who's only half-baked at enhancement magic.
He was just an ordinary person who didn't even have the power to save others.
He was nothing more than a righteous partner who drowned in his own ideals.
Emiya Shirou——
Whom are you trying to save? Sakura, your drowning ideals, or yourself?
