Crossbow arrows

In the end, the world was her crossbow.

As soon as Kamijou Touma realized that, ten pieces of destruction rained down from the
heavenly dome above.

What exactly could this be compared to?

Perhaps a super-long railgun that targeted someone on the planet's surface after eternal
acceleration using straight guiderails stretching from one end of the universe to the other.

Perhaps a singularity weapon that created destruction unexplainable with Newtonian
physics by directly messing with the smallest particles dealing with mass and motion such
as the bosons and the Higgs particle.

In all likelihood, expressing it with words was meaningless.

Even if one gathered everything that could be expressed with words, it was unlikely one
could shoot down that crossbow.

It merely hit.

"...!!!???"

Kamijou Touma leaped to the side with all his strength.

...The first shot fell vertically from the heavens.

It held the destructive power needed to easily wipe out a planet or two, but it was beyond
the point of creating anything like a crater. This was no different from a rifle bullet fired
with the initial velocity of a sniper rifle piercing glass without breaking it. The arrow had
been fired with such great speed that it pierced the pitch black ground without waiting for
the impact to propagate.

[...]

Time stopped.

He was too slow to react.

By the time he heard a dull sound, the final arrow had already been absorbed into his
chest and accurately targeted his heart.

This was nothing as kind as piercing or breaking him.

In the instant of impact, Kamijou Touma's body was smashed to pieces from the chest
down. As his heart continued to writhe in midair, the tip of the arrow caught it and blasted
it to the farthest reaches of that world.
