Flinching. Yeah. Jurojin was afraid of someone so afraid on his team. Can you flinch when you pile-drive the bad guys into the ground? Probably not. That's why he was about to show everyone what's what with his new assignment: the detriment of this rock.
Upon hearing his assignment, the titanium trainee jolted into the air, landing with legs spread and biceps anticipating the go-ahead. The words of his sensei's sentences drug on like the drugs he would never injure his body with, but finally it came to an end!
Jurojin was apparently supposed to perform some sort of rock jutsu on a boulder near him. This is fortunate for him, as he knew a good deal about rock jutsu. Technically it's not called "rock jutsu," though he supposed his sensei had a moment of thickness and meant either "earth jutsu" or "steel jutsu." Either way, Jurojin was in business-- the business of toughness!
"The Boom" slowly marched over to his opponent. Jurojin couldn't help but glance over at his allies, specifically the skin-and-bones boy, and their attempts. It looked like he just copied Kurokk's jutsu like some kind of Shariken-clan guy. This prompted a unhearty chuckle, Jurojin's breast rising and flexing in amusement. "I'LL SHOW THIS BOULDER WHAT A REAL BOULDER LOOKS LIKE! STEEL RELEASE: PLATING TECHNIQUE!"
With his announcement and two handsigns, Jurojin's body becomes covered in steel, much shinier and almost industrial-looking than the inferior natural stone before him. "YOU'RE DONE FOR NOW! ARHAT FIST!"
While the Kanaduchi wasn't exactly sure what kind of animal an "arhat" was, he assumed it was something that would be able to crack and demolish a simple rock. However, while the sound of the collision was grand, and the boulder suffered a fist-shaped indention with cracks protruding predictably, even his metal-plated face showed signs of disappointment. "GRR. MY PUNCH-HOLES ARE USUALLY BIGGER THAN THAT!"
He reasoned, as if anyone had asked. "GGGRRRRRAAAAAHHHHHH!" This made him angry! One would be able to tell by the way he growled! He wouldn't let this small indent be the mockery of him! With another forceful stirke, this time with his palm, the boulder would shard off into a dozen pieces.
