This is just the story of a friend named Justice.

The story of a man named Shirou Emiya.

At a certain moment, at a certain time, a door that should not have appeared appeared in front of a man named Shirou Emiya.

He is just a half-baked magician who can only perform strengthening magic.

He is just an ordinary person who does not even have the power to save others.

He is just a friend of Justice who drowned in his own ideals.

Shirou Emiya——Who are you saving, Sakura, your drowning ideals, or yourself?
