Tsuna threw back Orrin's sword, and threw a hard uppercut. Orrin stepped back, Tsuna's fist just barely missing as he spun in place, bringing his heel up for a kick. Tsuna ducked under it as Orrin brought his sword down. Tsuna expelled flames from his gloves, pushing him out of the way of the black sword. Orrin was quick to chase as he spread his wings and flew after him, swinging his sword. Tsuna could block Orrin's weapon with a combination of his gloves and his own flames protecting him, but the constant attacks put Tsuna at a dissadvantage with no room to counter attack. It wasn't long before Tsuna's back was to a wall as Orrin swung his sword at Tsuna's head. Tsuna reached up to catch it only to see Orrin open his mouth and expell a stream of black flames. Tsuna found out quickly that these were no normal flames, but Dying Will Flames. Tsuna reached up and pushed back with his own flames, wich only worked to some degree. Tsuna took a chance and let go of Orrin's sword to push back with a blast of flames from both hands. The burst took Orrin by suprise and knocked him into back.
Orrin smiled, "How do you like my Dying Will Flames?" Orrin asked, though not waiting for an answer. "Do you know why my flames are black? Surely you've noticed the different colors of Dying Will Flames. There's a reason for that, just like the seven rings of Vongola, there are seven classes of flame. Each with their own attributes, and then there is mine. My flame absorbs all those it comes into contact with. My guardians give me a small portion of their flames daily. Just wanted to let you know about the instument of your own demise."
Tsuna still didn't respond, "Fine," Orrin said, "Be that way and ruin my fun!" Orrin lunged forward, sword first. He was suprised to see Tsuna stop the blade between his hands as his flames began to pulse. Orrin watched as ice began to form on his blade, creeping down the sword and over his hands and arms.
"Zero Point Breakthrough," Tsuna said, "Revised."
Orrin mearly smirked as black flamse burst from his sword, shattering Tsuna's ice. This suprised Tsuna as Orrin ripped his sword from Tsuna's grip. Spinning around Orrin smashed his tail into the side of Tsuna's head, knocking him quite a ways. Tsuna was quick to get up though and flew back at Orrin, taking the offensive, but Orrin was faster. He parried every one of Tsuna's attacks, to make matters worse, Orrin wasn't lying about his black flame absorbing others. Every time Tsuna's flame touched Orrin's, Tsuna could feel his own energy being sapped away. Suddenly, Orrin dissapeared from sight, appearing behind Tsuna, slicing him across the back. Tsuna fell to the ground in pain.
Orrin laughed as he rose up into the air, "I had hoped you to prove yourself more than this," he said as he raised his sword over his head. "That being said, you fared decently... for a human." Orrin swung his sword downward, a giant wave of black flames expelling from the tip. Tsuna lifted his hand in an attempt to block it, but the force was too great, coming down on him with a loud crash.
Orrin landed next to Tsuna's body, to his suprise, not only was he still alive, but concious, his Dying Will Flame still burning. He smirked as Tsuna tried to get up, but Orrin kicked him in the side, pushing Tsuna onto his back. "I comend you, Vongola," Orrin said, "You live up to the tales of yoru resiliance." Orrin knelt down and pressed his palm to Tusna's forehead, "And now it will be mine." Black flames appeared on Orrin's hand as he began to suck out Tsuna's own flames. As Orrin's flames continued to suck Tsuna dry, Orrin lifted Tsuna into the air as Orrin's wings lifted the two of them higher and higher. Once they were at a fairly decent hight, Orrin left Tsuna with just enough Dying Will Flames to stay alive as he reached for the Vongola Sky Ring around Tsuna's neck. "You don't deserve this," he said as he ripped the chain from Tsuna's neck, letting go of Tsuna and letting him fall helplessly to the ground where he hit, hard.
"If you think you can take this back from me, Vongola," Orrin taunted, "you're welcome to try. That is if you're still alive." Orrin laughed as he flew away from the battlefeild.
