A deafening sound reached his ears.

A moment later, a pointy-haired boy fell from directly above, poured his full weight into a flying kick at the back-worn unit of the Power Lifter, and finally tore Hamazura’s steel arm from the elevator shaft wall.

He did not even have time to cry out.

In no time, he was bound by gravity and the two boys fell together.

[...]

They fell together into the dark, dark elevator shaft.

They fell about three stories’ worth.

Fortunately, the elevator car was stopped partway down.

Even so, they produced a great roar much like the sound of a metal pot dropped to the ground amplified dozens of times over. The gyro adjustments of the Power Lifter and the assistance of Aneri allowed Hamazura to make a fairly clean landing.
