electrocute building frame

A few of the flustered men tried to withdraw farther inward, but Mikoto’s electricity put
a stop to that. Pale blue light flew from her bangs, striking a portion of the steel
framework, then immediately ran through the entire building. Anyone touching the
framework was instantly blown backward, and even those who weren’t were sent to the
ground, electricity piercing them from all sides as they tried to make their way deeper
into the metal coffin.
Some of the flabbergasted men tried to back away, but Mikoto’s lightning wouldn’t let
them off so easily. The blue and white sparks that were emitting from her forehead hit a
steel pillar, and the electricity instantly flowed through the entire building. All the men
who touched the pillars jumped in shock. The tower had seemingly become a steel cage,
as some of the electricity shot inwards from every steel pillar, electrocuting some people
who weren’t touching the pillars as well and causing them to collapse to the ground.
