takes down a mech with skill

Kamijou Touma held an oxygen tank the size of a hair spray can. It was the spare for the
diving mask.
And he shoved it into the metal arm’s elbow joint.
The biting pressure of the joint was enough for the metal tank to burst like a balloon.
With a dry popping sound, the arm holding Kamijou stopped moving and he slipped from
its grasp. The machine itself had not broken, but the sudden internal shock must have
triggered a safety.
“Aneri? Respond, Aneri!! Damn!!”
Once he realized the one arm would not move in the slightest, Hamazura swung the other
one.
However, Kamijou already knew what to do next.
He removed his jacket and, like a bullfighter, dodged to the side at the last possible second.
The coat remained behind and got caught on the steel arm. Specifically, the moving parts
of the unprotected elbow bit into it.
This stopped the other arm.
A human body would lose its sense of balance if the arms stopped moving. A common
experiment had people run for fifty meters with their hands tied behind their back. That
alone was enough for people to lose their balance. So what would happen when it was a
heavy Power Lifter that had thrown off its center of gravity by swinging its fists with all
its might?
A tremendous crash reached Kamijou’s ears.
Hamazura and the Power Lifter had fallen to the floor as if from a martial arts throw. The
machine lay on its side and Kamijou quickly circled to the stomach-side where Hamazura
was visible.
