Chapter : Growing Fang

Day 1

BAM!

Tsuna sitted with his butt on the hard ground and eyes widen in shock. Just a few inches from his separated feet, lay the infamous tonfa that have made a deep crack on the ground, being hold by it's owner that giving deathly glare to the brown haired boy. Tsuna can't thanked his hyper intuition enough for this outcome. He didn't even want to imagine the silver weapon landed in his head (because that's where he see him aimed before).

"Wha-?! Hi-Hibari-san?!"

Not caring with Tsuna's oblivious look, Hibari pull out his tonfa and then aim it straight to his face (again). Just barely in time, Tsuna rolling to his left side while shrieking at the sudden attack. But he couldn't react fast enough when Hibari maneuvered his attack to his right and hitting him right in the stomach, making him thrown a few feet away and hitting the nearest wall.

"Ouch….That hurt….Hi-Hibari-san! What did I do wrong?!" Tsuna ask with now bruised body as he looking at him with confused and fear.

Hibari straighten his back and making a stance while looking at him, "Nothing."

Tsuna gaped, "What?! So then wha- UAAA!" Tsuna escaped just barely again when Hibari suddenly attacked him without any warning and making big hole on the wall where he leaning just a second before.

"The baby said I must bite you to death before you reach school, so that's what I will do." He said while keep his attacks on his (supposed to be) boss.

"REBORN SAID WHAT?!" Now he see why Reborn forbid Yamamoto and Gokudera to walk with him to school!

Hibari smirking at Tsuna's horror face. "Oh, and if you late to class, I'll bite you to death."

"AREN'T YOU ALREADY DOING IT NOW?!"

Day 5

Tsuna running with unsteady breath as he keep glancing right and left in every intersection. He was already cornered by Hibari right after he went out of the house, but luck on his side as a very innocent looking cat suddenly passed by and Tsuna shove him(or her?) right to Hibari's face, making him stunned for a few second and enable Tsuna to ran away at that very moment.

Just 2 more blocks to go! Please please please please please God!

But Tsuna knew his pray is useless when something suddenly flew from his right and and pierced the wall beside right him, making him stop in his feet. He eyed the hanged tonfa with dread on his face and then turning REALLY slowly to his other side. Only to found a certain prefect with with dark eyes staring at him.

"I'll bite you to DEATH."

"HIIEEEEEEE!"

Day 10

Tsuna cross his arm in front of his face, trying to block the tonfa that kept attacking him nonstop while wincing in pain. Yes, TRYING. Because most his effort is useless as the steel weapon just smashed through his hand and making Tsuna hitted by both the tonfa and his own hand.

"Hi-Hibari-san! Can't we at least skip today?! I got test today!" He said with already bleeding face. Even the school nurse already giving up trying to heal his wounds everyday!

"No." was his short answer as he keep attacking the shorter brunet and maneuvering around while Tsuna keep trying to dodge and blocking his attack.

"Bu-but!" his plead cutted sharply as Hibari aim for his right head, and Tsuna have to use his right hand to block it even though knowing it would made a large bruise on it.

He didn't know what haunted him at that moment. Maybe because he didn't want Kyoko-chan to get even more worried over his bruised body everyday. Maybe he just getting tired of running around trying to escape from his own blood lusting cloud guardian. Or maybe he just didn't want to be scold for arrive late for the test.

Seeing the opened spot in front of him, his body suddenly move on its own as his free left hand making a clean hit on the prefect's stomach and resulting him to took a step back. Having just realized what he have done, Tsuna's face turned pale while as he skhrieking a fast forward speed of "Imsorry!Imsorry!Imsorry!Imsorry!"

But unseen by him, Hibari smirked instead.

"Took you long enough, herbivore."

Day 30

Tsuna running as fast as his leg could take him, not even care to glancing right or left anymore, as his only focus is the big school gate that he could already see in front of him. His joy cutted short when he felt deathly intent from his right side, but thankfully he reacted fast enough to block a pair of tonfa before it succed in hitting him right in the head.

The skylark smirked as he push himself forward and send a flying kick at his stomach. Tsuna flip around to evade it and then hit his attacker back using his fist. But Hibari still faster in his reaction as he use one of his tonfa to protect his back, and using another one to send another hit while whirling around to face him again.

They sparing in close range like that for another few seconds before Tsuna finally found a chance to tackle Hibari and making him fall on his feet, then marking his winning for the day as he stop his fist right in front of the skylark's face. Not even waiting for his opponent(?) to stand up on his feet again, Tsuna quickly dash away to reach the school ground before the bell rings. Leaving Hibari in that state alone. He would never choose the option to face the skylark's wrath, especially doubled if he's late to school.

Hibari smirking at the younger boy's back with amused face as he standing up again, suddenly being perked up at the resistance he have been receiving for the past few days. "Wao, so you COULD be an Omnivore if you want."
