3D explosion

“So allow me to show you how I deal with that.”
Carissa stabbed the end of Curtana Original into the ground.
The great noise of a shockwave pounded on Kamijou’s ears.
With the second princess in the center, a dome-shaped storm of destruction with a
radius of five hundred meters erupted.
She had most likely taken the flow of magic power focused on the all dimension severing
spell and changed it to a different route. Although the created destructive power was not
as high as the power needed to slice through other dimensions, shockwaves were
scattered evenly in all directions in the three-dimensional world.
It was basically an explosion.
The ground was torn up, trees were knocked down, and the large wall of destruction
reached Kamijou in an instant.
“Oooooooooooooooohhhhhh!?”
As he yelled, Kamijou held up his right hand.
However, that failed.
The power was both too great and too continuous, so Kamijou’s right hand was not
enough to completely negate it. He had lost his memories, so he only had the knowledge,
but he was forcibly reminded of Innocentius and Dragon Breath.
A terrible pressure attacked his right hand, he heard the unpleasant noise of his bones
creaking, and pain ran up his arm.
Pushed by that power, it took less than two seconds for his feet to be lifted from the
ground.
Once he was in the air, the rest was simple.
Kamijou’s body flew further up into the air.
The dome-shaped explosion had a radius of five hundred meters.
Kamijou’s body was fired diagonally up by its force until he was two hundred meters up
in the night sky. In the instant when the force pushing him up and gravity were in
equilibrium, Kamijou Touma floated motionless in the air and looked at the sparse night
view of Folkestone.
(What do I do...?)
The countdown for his fall began.
And Kamijou’s right hand did not have a convenient power that would allow him to land
safely from a fall of two hundred meters.
(What do I do!?)
The always present force of gravity bared its fangs towards Kamijou Touma.
