As Mikoto’s thoughts floated up into the air, Accelerator sneered as he spread his arms
wide up into the night sky. In the next instant, the wind flowing through the city focused
on one point. It was a point a hundred meters above Accelerator’s head. When the
raging wind gathered there, a bright white light appeared as if from welding.

It was plasma.

Compressing the air created heat. Internal combustion engines used that fact. By
compressing the city’s air with a ridiculous compression ratio, it had turned into a mass
of heat exceeding ten thousand degrees Celsius. This forcibly caused the atoms in the
nearby air to split into cations and electrons which turned them to plasma.

That point of light swallowed up the surrounding air and instantaneously grew to have a
radius of 20 meters.

The surrounding darkness was annihilated by the pure white light.

The heat of ten thousand degrees caused a burning pain on Mikoto’s skin.

“...!”

A chill ran down Mikoto’s back that seemed to freeze her spine.

That was not an attack that humanity could defend against. That mass of heat could dig
up a nuclear shelter from the ground, so there was no way a flesh-and-blood body could
do anything about it.

Misaka Mikoto was certainly Academy City’s strongest in the category of Electromaster.

Plasma was created from the atoms separating into cations and electrons, so she may
have been able to return the plasma to the original atoms by putting the electrons back
together with the cations.

But how would that help?

Even if she did manage to return the plasma to its original state, Accelerator would just
gather the wind again to recreate the plasma. To seal Accelerator’s attack, electricity did
not cut it. One needed the ability to control wind like he could. But Mikoto could not
control wind with her electricity techniques. Mikoto gritted her teeth at the uselessness
of her power in that situation.
