When the Emiya family of the previous generation determined the "Origin" of their son and heir, at a loss they named him "Kiritsugu" due to the strange results.
Basically, he possesses the dual attributes of "Fire" and "Earth". To be specific, they were composite attributes, "Severing" and "Binding". That is the form of his soul that was born with him, and the true form of his "Origin".
Sever, and bind – it’s not exactly the same as being called "destruction and rebirth", because Kiritsugu’s Origin has no meaning of "recovery". For example, a string that is cut and then connected again would have change of thickness at the point where the knot is tied. That is, the action of 'severing and binding' would cause irreversible "corruption" in the target.
Kiritsugu became particularly aware of his Origin when he was asked to complete some hands-on work. His hands weren’t very skilled. If a normal contraption breaks down, he could fix it. But if it comes to delicate machinery then everything would suddenly become the opposite. The more he wanted to fix it, the worse the damage would become for the machine.
As a matter of fact, Kiritsugu’s handcraft isn’t extraordinary. If a normal metal wire snapped, the original function can be restored by just connecting it back together. However, if he were to fix a delicate electric circuit using the same principles, the result would be fatal. It wasn’t something that would work as long as everything is connected. If the connections become out of order, the circuit would lose its function. This wasn't something created by Kiritsugu’s personality or temperament; from magecraft’s point of view, it is the true essence of the root deep within his soul.
Emiya Kiritsugu utilized his extraordinary "Origin" to its fullest extent when he created his Mystic Code. The first and second ribs on both sides were cut off and taken out of his body. The extracted ribs were grinded into dust, condensed with a craft to preserve the soul, and sealed within sixty-six bullets as their core.
These bullets would actualize Kiritsugu’s "Origin" on the target when it hits. If it were to hit a living creature then there would be no wounds or bleeding, but the place where it was hit would appear to be suffering necrosis. The surface may seem to have healed, but the nerves and capillaries wouldn’t be regenerated properly and the original function would be lost.
Moreover, as a Conceptual Weapon, this bullet poses an even graver threat to magi in particular.
