Today, Katsuki and his class, along with his teacher, went to a laboratory, they were looking around at the experiments, most were animals with mutations or modifications

Katsuki, at one moment, got separated from his class, he looked around, until he spotted a suspicious experiment cell, it was covered, like if it was secret

He told his class and the teacher, and they all went to check what's in that cell

What the heck is in that cell? I swear if it's an illegal experiment..
