smacked between a mech and floor

The three meter mass of steel ran and then jumped toward him. Kamijou was not sure
whether it weighed several hundred kilograms or a full ton, but he knew what would
happen if it crushed him.
(I’ll be killed instantly!!)
He desperately rolled to the side and managed to evade.
As a roar burst out, Hamazura swung the two joysticks around. The arms followed the
same motions and a giant press-like palm savagely swung down.
Hamazura had predicted his action.
With his torso held between the palm and the floor, the flow of Kamijou’s blood was
thrown out of whack.
“Bghueh!?”
The arm opened like an alligator mouth, grabbed the boy’s torso, and lifted him up.
