Regulus shakes island

What was emitted from Kojou’s arm was a dense mass of magical energy in solid form. In other words, one of the beings called a Beast Vassal. However, it was not even in the same dimension as the Beast Vassals people knew about.
This was a lightning storm destroying everything in its path.
The giant, out-of-control lightning strike mowed down the buildings aboveground; the shock waves thus created became wildly blowing windstorms. Kojou was fully enveloped by the light as lightning arrows indiscriminately scattered all around him.
It was like a vast storm cloud had suddenly appeared at ground level.
All of Itogami Island shook as if it were being bombed. The surrounding sea raged like a tsunami.
