Recalling Liena-senpai's words, I pulled back the chain with force
and right before it extended completely, I made a full swing with a
yell.

“Sei!”

The end of the chain that rushed through the air like a dark grey
snake attacked where the three centimeters thick iron rods
intersected without miss, scattering dazzling sparks in the darkness.

Blang! Along with the loud noise that rang out, the bars were blown
off from their frames above and below them, vehemently striking
the grid of the opposite cell before they fell onto the floor. If there
were any prisoners there, they must have thought it was a divine
punishment from Solus or something.
