passed out from 3D explosion

“Ow...”
Kamijou Touma awoke with a dull pain in the area of his backbone.
He was inside an old car left in the mountains near the foundation of an old ruined
building. The car seemed foreign and was quite large making it look like it had bad gas
mileage. However, it wasn’t all too clear whether it was accurate to say he was “inside”
the car. It had no roof and its doors were missing. Kamijou was lying face up in what
was little more than the chassis.
Beyond where the door should have been was a dark forest. It was still the middle of the
night, but his eyes must have gotten used to the darkness because he no longer saw a
single shade of black. Instead, the darkness had its own type of light and darkness and
color allowing him to see objects’ silhouettes. For someone who lived in Tokyo like
Kamijou, truly experiencing starlight was a rare thing.
(What...happened...?)
Kamijou sat up on the sofa-like backseat and tried to sort out the information in his
head.
(...Wasn’t I not able to negate the second princess’s attack and then got blown away way
up in the sky?)
Common sense told him that there was no way he would have survived falling from a
height of a few hundred meters. That was well beyond the level where something
cushioning him on the ground would save him. Nevertheless, Kamijou was in one piece
and didn’t have any broken bones. In fact, he had nothing more than a few scratches.
And then...
“So you’ve finally decided to wake up? You certainly are carefree.”
Kamijou turned around in the direction of the low male voice.
“Ee!? Acqua of the Back!!”
