iron sand wave

The independent unit seemed to have given up on the bombings, but they had brought
out a tank unit that had been hidden behind a hill. Even if they were prepared to be hit a
few times, they would be completely blown away if dozens of tanks focused their fire on
them.
“By Misaka’s estimations, we will be hit by the blasts twenty times before we can travel
five hundred meters, says Misa—”
“Then we’ll finish this before that!!”
A black shadow squirmed around Mikoto’s tank.
No.
It was a large amount of iron sand that had been sleeping below the snow. She
thoroughly gathered it from approximately two hundred meters around her and brought
it together using magnetism.
It must have looked like a wall to her enemies.
That wall of despair was like a giant tsunami about to strike the land.

That was the #3 Level 5.
She was not just a cannon.
There were only two people she knew who she could not handle even with skillful
application of her power. Those two were the espers who stood at the extremes. One at
the extreme of justice and one at the extreme of evil.
“Goooooooooooooooooooooooooooooooooooo!!”
As she yelled, the huge mass of iron sand passed by overhead and crashed into the
enemy forces ahead. Like an undulating tsunami or like a living snake, that mountain of
iron sand swept across while vibrating at high speed. The independent Russian unit was
unable to deal with it.
Of course they weren’t.
No matter how many times they shot it, the swirling iron sand did not slow down in the
slightest.
The tank being controlled by the Sister leisurely drove into the center of the confused
enemy lines. Mikoto pulled herself out of the hatch completely and looked forward.
