hundreds of drills

In contrast, Mikoto used the iron sand to create several hundred drills and run them
through with electricity, readying them to pierce Sogiita from all over the place, and shot
them out. Manipulating the iron sand at such a speed that there was no time to breathe,
she also let the empty cans ionize into plasma to distract the enemy’s eyes before
running into him, displaying all sorts of attacks.
