FATE/STAY NIGHT IS A FUCKING AWESOME VISUAL NOVEL WITH PORN IN IT. AN ANIME AND MANGA BOTH EXIST, ONLY WITH A LOT LESS PORN.

IT CAN BE BEST SUMMARIZED AS:

I AM THE BONE OF MY SWORD
STEEL IS MY BODY AND FIRE IS MY BLOOD
I HAVE CREATED OVER A THOUSAND BLADES
UNKNOWN TO DEATH
NOR KNOWN TO LIFE
HAVE WITHSTOOD PAIN TO CREATE MANY WEAPONS
YET THOSE HANDS WILL NEVER HOLD ANYTHING
SO AS I PRAY, "UNLIMITED BLADE WORKS"

MAKE UP YOUR OWN UNLIMITED BLADE WORKS PARODY FOR INFINITE LULZ.

JUST GO PLAY THE GAME ALREADY. OR WATCH THE ANIME. WHATEVER WORKS FOR YOU.
