Kiritsugu had been around almost half of New York an hour ago and finally brought a military surface-to-air portable missile launcher from the black market.

Right now, Kiritsugu was standing in a motor boat floating on the sea, waiting for Natalia’s plane to appear in his sight. The giant airline needs to circle a while before landing at the New York International Airport; Kiritsugu’s current position can roughly get the plane into the range of his missile.

While he was purchasing the weapon and choosing the spot to fire, Kiritsugu once again doubted the construction of his own mentality.

Viewing from the perspective of avoiding a larger tragedy, it is a correct response for him to calmly face Natalia’s death.

However, what is he who gives up on the final ‘miracle’ that would make the woman he loves survive, and instead kill her with his own hands?

It would be good if everything was only an assumption, but right now Emiya Kiritsugu was facing the cruel truth. Soon, he would erase Natalia by his own hands. Now, A300 had appeared at the sky at the break of dawn with sparkling silver wings.

“… Perhaps I, have really lost it.”

Natalia still believed without a doubt that Kiritsugu, on the other side of the radio, was in a hotel in New York, so she said leisurely with no caution.

“Maybe I would never end up saying those things if such a big mistake didn’t occur. It seems my time is up, too. Should I be retiring…”

“– If you retire, then what do you plan on doing after?”

Kiritsugu still faked an even voice. Meanwhile, his two hands have started to set the missile launcher onto his shoulder, and aimed the missile at the airliner.

“If I lose my job… haha, then I may really become your mother.”

Even with his eyes running full of tears, he was still able to accurately decide the distance to the target… it was within 1500 meters. A certain hit.

“You… really are my family.”

Kiritsugu said softly, then he released the missile.

In the few seconds that the missile had to be manually directed, Kiritsugu had to keep the aim on the airliner that Natalia was on and all his memories about her resurfaced in Kiritsugu’s mind.

But that torture did not last long. Soon the missile locked onto the heat radiation the giant commercial airliner emitted out. The missile left Kiritsugu’s control, and rushed mercilessly towards the target like a hungry shark.

The missile hit squarely on the gas tank beneath the wings; Kiritsugu watched the plane tilt and fall downwards.

The collapse afterwards was like a sand picture blown apart by a stormy wind – the masses of iron that lost its thrust was dismembered like rotten wood, and became a cloud of fine dust that silently fell onto the surface of the sea. The carcass of the plane that fell in the rising morning glow danced like confetti at a gala.

The first sliver of the dawn’s light that shone out from the other side of the horizon didn’t touch Natalia’s face even at the end. Basked in the morning sun all alone, Emiya Kiritsugu started crying soundlessly.
