shotgun light

Bright sunlight poured down like it was midsummer, but the sky flickered like a sky full
of stars. Before Mikoto could figure out what it was, the downpour of destruction hit the
surface.
“!?”
Everything was swallowed up by the noise.
The one-sided roar stole all other information from Mikoto’s ears. The objects raining
down were over one thousand brilliantly white beams of light. With the opened
parabolic antenna in the center, an area with a diameter of ten kilometers was utterly
blown away.
Mikoto and Shirai were lucky that it had not been one giant bomb. The randomly
scattered attack was more like a shotgun blast, so Shirai could carefully teleport around
just barely managing to evade.
A huge amount of seawater was evaporated.
