Kyouya feels a tap on his shoulder. He slides the lock into place and puts down the semi-automatic gun. He doesn't know the name but he knows he loves it. Kyouya takes off the muffling headphones and turns to Reborn.

"Take a break," Reborn says. "Tsuna and Hayato are about to arrive."

"Why do I care?" Kyouya asks but he does step back from the makeshift firing range he had installed deep inside his backyard.

"I didn't have to let you try the auto as well as the handgun and sniper," Reborn replies, easily disassembling the gun.

Kyouya sighs. You let this man take an inch and he'll force you back a mile.

Hayato adjusts his feet for a more solid stance and tightens his left arm around Kyouya's neck. Not enough to make the other teen unable to breathe, but still keeps pressure to make the other uncomfortable. His right acts as a lock, bent with the elbow jutting out over the other boy's shoulder as the left hand grips the bicep.

"Okay, so to get out of it," Kyouya begins, leaning back into Hayato's chest as he speaks to the avidly watching Tsuna. "There are a few ways, but at your level its best to keep things simple."

Tsuna nods obediently and Hayato tenses in preparation.

"Turn your head towards the small gap where the elbow bends," Kyouya dictates as he demonstrates his words. "This will take some pressure off your trachea and carotid."

At Tsuna's blank look Kyouya rolls his eyes.

"Your windpipe and blood flow," he rewords. "Aim for the arch of the foot," Kyouya lectures, stepping back onto Hayato's bare foot gently. "If you stomp on the toes, that only irritates people. The arch can break if you do it hard enough."

Hayato gulps.

"Then its elbow to the side," Kyouya continues, pulling his arm up and pressing an elbow to Hayato's ribs. "It depends on how tall your attacker is, but try to aim for the floating ribs down the bottom, they tend to be thinner and weaker."

In an actual fight Kyouya generally aimed for ... anywhere because his strength made it rather unnecessary to pick and choose his targets. This little demonstration also isn't something a normal person can do by any stretch of the imagination, but Reborn really only needs Tsuna distracted for a little bit while he goes off to set up some chaos.

"This will generally make their grip slacken if not entirely release you," Kyouya says, shoving Hayato's arms out a bit to where he wants it.

Hayato complies obediently.

"Then the throw." Kyouya plants his foot outside Hayato's and twists as he pulls on the same side's arm to complete the hip throw.

Hayato trips over Kyouya's leg and hits the floor.

"Do you have that?" Kyouya asks.

"Foot, elbow and throw," Tsuna summarises happily.

"Alright, then we'll do this for real." Kyouya dictates.

At once, Hayato lurches up from the floor, his arms locking across Kyouya's neck and tightening painfully enough to cut off any breathing and block the blood flow. Kyouya turns, stomps down and slams an elbow deep into Hayato's soft tissue.

The other lets out an involuntary cough and twists to try and defend the hit area with his arms, despite them still choking Kyouya.

Then the chairman's head snaps back viciously before flipping Hayato to the floor.

Hayato clutches at his nose, a loud and very rude curse escaping him as he curls up on the floor.

"And that is how you get out of a headlock," Kyouya says simply.

"You broke my nose," Hayato snaps nasally. "What the fuck? That wasn't what we planned!"

"You're attacking me, why would I give you a full script?" Kyouya scoffs, not even facing Hayato. "And I hardly touched you. If I didn't break your foot and I didn't break your ribs, I most certainly didn't break your nose."

Tsuna, watching with wide eyes as blood seeps between Hayato's fingers as he holds his nose, isn't so sure.

"Yes you fucking did!" Hayato cries, getting to his feet. "Look how much I'm bleeding!"

Kyouya rolls his eyes and finally turns to face the other teen. "Come on," he says with a sigh, stepping forward and reaching up to take hold of Hayato's wrists. "Let me see."

Hayato glares but lowers his arms anyway.

Kyouya's eyes flicker across the wound and he gently presses the skin around the injury. He looks back at Hayato's eyes after a brief moment. "It's not broken, it just took a hard hit. Head wounds always bleed a lot because of the blood pressure."

Hayato frowns. "It feels like its broken."

"No, this is what broken feels like."

Hayato jerks back and gets halfway to raising his arms in defence when Kyouya's hand connects.

There's a crunch and Hayato is thrown back, hitting the ground five meters away head first. A scream of rage mixes with the groan of pain, and the hands that are covering his nose again get soaked with more blood. He curls up on his side, too focused on the throbbing pain radiating from his face to try and grab his dynamite.

Kyouya calmly pulls a pure white handkerchief from his pocket and wipes the smudge of blood from the heel of his hand as he turns to Tsuna. "Now I'll put you in a headlock and you'll try to get out," he plans, tossing the cloth over his shoulder.

It lands perfectly over the side of Hayato's face.

"You broke his nose!" Tsuna shrieks in horror.

Tsuna rushes past the unconcerned prefect and falls to his knees beside the downed teenager. He snatches up the handkerchief and starts trying to wipe blood off Hayato's hands and face without putting any pressure on the injury.

"Are you still focused on that?" comes Kyouya's exasperated sigh.

"It happened like three seconds ago!" Tsuna cries, incredulous.

Hayato takes the cloth and holds it under his nose with one hand to catch the steady flow of blood, while the other hand rips a few sticks of dynamite from his pocket. He scrambles up to his feet, practically spitting fire even as his eyes water from the injury being so close. "I'm sick of your shit, asshole!"

"I like watching you cry," Kyouya muses.

The hand holding the white cloth raises its middle finger pointedly.
