door car hook explosion

The second wave arrived before Saigou and Sugiyama could determine what was causing
that roar of rage.
The second wave took the form of a thick metal door.
The metal door flew at horrific speed while rotating vertically. It came so close that it
almost grazed across Saigou and Sugiyama’s skin and then slammed into the center of
the parked Anti-Skill patrol vehicle like a gigantic circular saw.
Sparks flew and the vehicle was bent into an L-shape.
It was as if that completely normal vehicle had suddenly been struck from the side by an
artillery shell. The back half of the vehicle stayed the same while the front half was
smashed up and bent directly to the side. The vehicle did not even slide to the side. The
blow contained such force that the area struck by the “shell” opened up like a blooming
flower of destroyed metal. The metal door that destroyed the vehicle had enough
momentum to continue on. Only after smashing the asphalt to pieces did it finally come
to a stop. The gasoline pipe that had been torn apart touched an electric cable that had
been disconnected. A small spark formed.
And that was all it took.
After that single blow from the side, the vehicle exploded. Flames and smoke were
scattered around the area.
