My son became a Heroic Spirit, my daughter became the Holy Grail, and my wife became a ghost.
I, Emiya Kiritsugu, became a Grand Assassin…
And then, the day before I became a Grand, my mentor, King Hassan, suddenly, dropped dead!
This is the tale of an idealist who saves the world through pragmatic actions.

Alaya: Starting today, you'll be learning assassination techniques under King Hassan. Good luck! I believe in you!
Kiritsugu: All right.
King Hassan: There isn't enough time in this world for you to assassinate everyone. Here, take this greatsword and do your best. You'll earn the title of the Twentieth Hassan sooner or later.
Kiritsugu: …
Years later
Gaia: What exactly are you trying to say, Emiya?!
Kiritsugu: I'm done being an ally of justice! Gaia! Take this, my RPG of humanitarianism!
