Mikoto Misaka - Lightspeed Lightning #1

Her lightning moves at lightspeed.

> The sparks poured out and connected to the railing of the bridge where they vanished. The cat moved away from Mikoto because of the noise of the sparks.

> There were only 7 meters between Kamijou and Mikoto.

> That distance was too great for Kamijou to reach her in one step, but it was well within the range of Mikoto’s electrical attacks that moved at the speed of light.
