terrorists gooned on

Some of them tried to shoot with their rifles from behind cover.
Some of them tried to use hostages to stop their opponent’s movement.
Some of them tried to use dynamite to destroy the columns and bury their opponent in
the rubble.
These were good actions, except it was all meaningless.
Forget about it even having an effect, there was no value in even trying.
The bullets didn’t work.
As soon they touched the monster’s skin, they were reflected back and shot the terrorists
themselves.
Taking hostages didn’t work.
As soon as they tried to reach for the kids, their wrists were twisted in an unnatural
manner.
Dynamite didn’t work.
As soon as they tried to push the button for it to explode, their fingers were blown away
along with the button.
(No...)
It was more than just that, one of the masked members of Spark Signal thought.

That face of his that could not be seen from outside was already covered with cold sweat.
He felt that the essence of the escalating terror in his heart was more than just those.
Yes.
The #1 Level 5 of Academy City, Accelerator, was taking all of this completely seriously.
He didn’t excessively use his overwhelming power. Even seeing the terrorist falling one
after another he did not get careless. If he relaxed then maybe they still had a chance,
but Accelerator didn’t even give that small possibility to his opponents.
Sometimes with his ability, sometimes with his handgun, he always used the smallest
amount of effort to obtain the greatest results. It was no longer a battle between humans,
or even between humans and a monster. Simple destruction that needed no emotions.
