iron sand electric cage

As she said that, she let the iron sand that was accumulated from the surrounding dirt
and sand formed objects that were as large as golf balls, letting them float around in tens
or hundreds.
Like a disco ball rotating, the black figures danced about in the midst of the bluish-white
sparks. Standing in the midst of this amazing scene, Mikoto let out a fearless smile, and
the numerous balls flew towards the girl.
Nayuta could see the flow of the energy, but the electric discharge between the iron sand
balls couldn’t be seen. She most likely thought that the opponent wouldn’t use her full
power, as she used this chance not to escape but to enter the crowd of balls and close in
on Mikoto.
Next, she realized her stupidity and frantically tried to let her body escape.
But it was too late.
The iron sand balls collapsed into even smaller ones and expanded out, surrounding
Mikoto and Nayuta’s surroundings. They then emitted bluish-white sparks.
With the park as the center, Mikoto used the iron sand balls that were conducting
electricity to cover the entire place in a dome, letting electricity flow through them. The
gaps between the balls let out electricity, forming a large electric cage with Mikoto at its
center.

Looking at Nayuta who was trapped in this case, Mikoto let that “cage” slowly shrink
towards her.
“!”
Nayuta wanted to let a part of Mikoto’s power overload and expand the iron sand balls,
but Mikoto immediately repaired that and regenerated the damaged cage.
The girl’s ability could “overload”, but it couldn’t “stop”.
Well aware of that, Mikoto let the electric cage spin fast and close in.
“So now what? Do you still want to continue!?”
