Summary: Tsuna has Earth Flames, and his attempt to save Yamamoto goes very differently. Beta'd by SableDreamer.
The information Iemitsu had given him on his student was wrong. Granted, Reborn hadn't expected the idiot to give him the most accurate information, but for it to be so very wrong was baffling. Tsuna was clumsy and shy, yes, but he seemed to do fine academically. Tsuna's grades were not stellar, but they were high enough to place him near the upper half of his class. His grades fluctuated from subject to subject, but overall, he was a good student Reborn could whip into academic-shape easily enough.
There was also the distinct lack of sky flames from the boy. Reborn had yet to shoot Tsuna with a Dying Will Bullet, but the hitman had been around other Skies before. Even when those Skies had not been using flames, there was a certain aura of peace and welcoming that surrounded them. Tsuna's aura was similar, but it was not the aura of a sky flame user, and Reborn had no idea what type of flame user Tsuna was.
For the first few days after his arrival, Reborn continued to contemplate Tsuna's possible flame types, but he had little luck. He had hoped that the fight between his student and the Smokin' Bomb might help clarify things, but no such luck. The only unusual part of the fight was how the Smokin' Bomb's dynamite never managed to hit Tsuna. It would fly to the side just enough to keep Tsuna out of the blast radius, but that could have been any number of other factors. Without any sort of proof, Reborn was hesitant to claim Tsuna to be the cause. Because of the constant misses, Reborn never had to shoot Tsuna with a Dying Will Bullet to deal with the dynamite.
It was the Takeshi Yamamoto incident that finally allowed Reborn to see the true nature of his student's flames. After the battle, Tsuna had earned Gokudera's respect and his loyalty, gaining his first subordinate, and by extension, friend. The next few days had been relatively peaceful, with Tsuna spending most of that time trying to convince Gokudera into being more informal around him. It had yet to work, but Reborn's student was determined. Then Tsuna was approached by Takeshi Yamamoto.
Reborn did not know the boy personally, but he'd heard of his father, Tsuyoshi Yamamoto. Yamamoto asked for advice about baseball, on how to improve his average that continued to drop, despite increased practicing. Tsuna was not sporty, Reborn knew, but Tsuna still had tried to offer the other boy advice. The given advice was fairly solid; Tsuna had suggested Yamamoto take a break and rest before practicing again.
Yamamoto had taken the advice with a smile, but Reborn could tell that the boy did not like the suggestion much. The next day, Yamamoto came to school with a broken arm. This didn't surprise Reborn, who had seen the signs of over-training, but what did surprise him was Yamamoto's decision afterward. Namimori's baseball ace had climbed up onto the roof, his smiley façade shattered. His features were blank as he neared the roof's edge, his hands pressing against the fence lining the roof.
Naturally, Reborn sent Tsuna to deal with it. It was his student's potential guardian after all. So Tsuna climbed up to the roof too, already doing more than many of Yamamoto's supposed friends, who all remained firmly on the ground and watched from below. The clumsy boy was attempting to talk the other boy down and guide them both away from the edge of the roof. Tsuna was doing well too, sympathizing with Yamamoto's struggles and perceived failures. Slowly, the boys edged away from the fence, but then Yamamoto had stumbled, sending himself and Tsuna tumbling over the edge of the roof, rusted fence giving way beneath them.
Reborn watched in horror as the two disappeared over the edge. He quickly hopped from his current position to the remains of the fence and looked down. Tsuna and Yamamoto had just passed the first row of windows, clinging to each other desperately, and were gaining speed. Cursing, the hitman pulled out his Leon-gun and loaded a Dying Will Bullet. Before he got the chance to shoot, something strange happened. Tsuna and Yamamoto reversed directions and began moving upwards with the same great speed. They rocketed up over the side of the roof and hovered there for a moment before beginning to crash down onto the roof.
Tsuna grabbed Yamamoto, pulling the other boy up and positioning himself to take the worst of the impact. He did, his left forearm taking the brunt of the fall. Tsuna screamed, and Reborn winced at the piercing crack as the boy's forearm broke and splintered. Yamamoto was fine, barely a scratch from the fall, but he looked ill, the terrible sound reverberating in his ears.
Tsuna was sobbing now, half-conscious and fading fast. Yamamoto had recovered enough to pull the injured boy into a sitting position and a gentle embrace. Reborn made his way over to them, still baffled by the blatant defiance of physics he'd just witnessed. 'No, now is not the time,' he thought, shoving all those thoughts to the back of his head in order to focus on his student.
"Yamamoto," he said, staring at the one holding Tsuna so gently.
Shock flashed across Yamamoto's eyes upon hearing the infant speak, but he responded nonetheless. "Yeah, kid?"
"Come with me. We must take Tsuna to a hospital." Reborn watched for a moment as Yamamoto pulled Tsuna into his arms and began to walk carefully, as to not jostle Tsuna's broken arm. Then Reborn started walking too as he mulls over what he'd just seen. Tsuna had done something to the dynamite. Reborn was sure now, and whatever he'd done in the fight had been done to an even larger extent saving Yamamoto. He was intrigued now; He'd figure out Tsuna's flame type because the boy most certainly was not a sky. Perhaps it's time for some research about flames…
