rapid fires railgun

That giant dragon gained an extra burst of speed as if crossing the final line.
That dragon had cost seventy jewels. Even if it ran headlong into a ten-car linear motor
train, it would smash the train without taking any damage itself.
However…
Something happened just before the dragon struck.
“Shut up!!!!!”
Mikoto jumped back as if performing a backflip.
Powerful magnetism pulled her forcefully toward the back of the train. It looked like she
was throwing a dropkick with the force of a shell. That short and slender girl would be
smashed to a pulp the instant she touched any spot on the tunnel, but she did not hesitate
to jump from the safe zone and toward Níðhöggr Vol. 02.
The greatest roar yet burst out.
And that roar was followed by many more.
As Mikoto launched herself horizontally toward the dragon, she could be seen pulling
several arcade coins from her skirt.
She fired repeatedly at point blank range.
This was the attack that gave her the nickname of Railgun and she fired it again and again
to her heart’s content.
The entire tunnel shook ominously and small fragments fell from the ceiling.
“It…can’t be…”
The giant dragon’s advance was stopped in an instant.
Freyja and the others’ on the moving train saw what could only be called its remnants
disappearing. Their minds had numbed to the point that they could understand nothing
more than that.
