Katsuki's quirk was nothing short of amazing. It's potential massive, and with someone like him wielding, practically unstoppable.

The amount of control he had to constantly be putting in...he prided himself on his efforts. Training vigorously to set off just the right amount of damage. Not enough to kill or seriously damage someone, but to knock em right on their ass.

But...even he couldn't control this.

Katsuki sat on one of the dorm couches, eyebrows furrowed and teeth clenched as he stared at his hand. Hand cramps. There was only so much output he could handle before his body began to turn on him. And they could get ugly.
