"Overthinking won't get you anywhere" Kakashi could hear Tomura's voice again but could don't know where it's coming from. "If you want to save the humans do much, I'll do you a favor and let you die with them!"
Suddenly, the fleshy walls started closing in on each other, making the prison smaller and smaller.
Kakashi stood in the middle of the walls which were slowly crawling towards, the place was becoming smaller, he had no choice but to move.
He took a step forward, expecting to be attacked by a spike but nothing happened. The wall kept getting closer till there was almost no room left.
Kakashi leaned his back on the first side and kicked the other side with force, trying to push it back. In other no to kill any of the transfigured humans, he didn't use karma in his attack but it was still effective.
The wall began to bleed as he kicked it again.
"Please, just kill me!" He could hear the poor souls begging for help.
