throws concrete that could break a wall

With the roar of the air bursting, the lightning spear directly struck the steel claymore.
Not even Brunhild was able to ignore that. The high voltage current passed from the
blade to her wrists and then rushed throughout her entire body.
Meanwhile, Mikoto swung her left hand. It was the same motion as that used in a
sidearm throw in baseball.
Something large moved as if following her palm.
It was a giant mass of reinforced concrete. It flew straight for Brunhild to perform a
deadly body blow.
Brunhild forcibly recovered from the electric damage in an instant and used her
claymore and her physical strength to stop that mass that could likely destroy a building
wall.
