They were all monsters!!!
Some had twisted bull horns growing from their heads, and skin as rough as tree bark.
Some were covered from head to toe in ghastly white bone spikes, like deformed hedgehogs.
Some had no fixed shape, slowly writhing across the ground like mollusks, leaving behind a sticky trail.
Others had twisted, deformed limbs and extra organs or appendages, their appearances bizarre beyond compare.
These "things" had retained some of their human consciousness.
The moment they saw Yo and the others, the entire prison erupted. The monsters howled and lunged at them.
"Eat... eat you! Meat! Fresh meat!"
"Help... help me..."
"It hurts... kill me... please, kill me!"
"Die... everyone dies... hahaha! Let me out! I'll make you all just like me!"

The hellish, terrifying scene made Naruto's teeth chatter, and he instinctively took half a step back.
Even Sasuke, with his steely resolve, looked ghastly pale as he gripped the kunai in his hand.
"W-what... what are these things?" Naruto stammered, his voice wavering.
Yo furrowed his brow. "Failed Products of the Human Body Modification Experiment!"
"Human body modification?"
Naruto and Sasuke stared at him in surprise.
"Remember Tsurugi Misumi, who could absorb chakra, and Akado Yoroi from the Chunin Ninja Exams?"
Yo explained, "They were also products of human body modification, but... relatively successful ones!"
"And these... are what happens when the experiments fail, or when the subjects are discarded as expendable or useless."
"Damn it!!"
At Yo's words, a surge of anger swept away some of Naruto's fear. He clenched his fists and gritted his teeth.
"Who could be so cruel as to turn them into this?!"
Just then.
"Well, well~~ I wonder who barged into my laboratory... I never expected it to be someone I knew!"
Just then, a hoarse, resonant voice
