blocks lightning

Bluish-white sparks flew from the girl’s bangs like a horn and a spear-like line of
lightning flew towards Kamijou.
There was no way to evade. After all, he was against a bluish-white lightning spear shot
from a Level 5’s hair. It was an experience like watching a thundercloud fire a bolt at
light speed and then trying to dodge it.
An explosive noise followed after a slight delay.
Kamijou immediately held up his right hand to protect his face and the lightning spear
struck it. It rampaged through Kamijou’s body and sparks scattered in every direction
and into the bridge's steel framework.
…Or so it had seemed.
“So, why are you completely unhurt?”

Her words seemed lighthearted enough, but the girl baring her canines was glaring at
Kamijou.
The high voltage current that had scattered into the surroundings had been powerful
enough to burn the steel framework of the bridge, yet, Kamijou’s right hand had not
been blown off by the direct hit. …In fact, it lacked even a single burn.
Kamijou’s right hand had erased the girl’s electrical strike that numbered a few hundred
million volts.
