Third chapter and only a little bit more about Shiyo is going to be revealed. Please review.

Diclaimer: I don't own Katekyo Hitman Reborn.

Chapter 3

Shiyo's smile was filled with confidence, but also with a sliver of steel in it. Hibari, always relishing a fight, went for her with his tonfas. She blocked them with her own, which had appeared seemingly from nowhere and were a sparkling silver. Her skill and speed matched his own, and it was close to impossible to see them as they went at it. But the frightening thing about the fight was not the skill or the speed or even the danger both of them were facing, but the wild ecstasy with which they both fought.

From Tsuna's point of view, this whole twin sister situation was still pretty hard to believe. How could he possibly come to believe that he had a twin sister he had never known about, and furthermore, she was and had always been part of the mafia. It bothered him, too, that his so-called sister was living on her own. She had seemed pretty dangerous at first, but the more he saw her, the more he felt like she was just a normal girl. She couldn't possibly have been in the mafia, she hadn't shown any skills like Bianchi, Reborn, or even Dr. Shamal.

But then again, she had also undergone the strange personality transformation. Had their initial meeting been all dreamt? Tsuna had gotten used to the unusual after meeting Reborn, but this was going a little too far. He shook his head hard, then laughed a little to himself. Why was he bothering about this? He would have to just ask Reborn about it later. Reborn seemed to understand everything and had seemed to know Shiyo when she had turned up. But there definitely was no way that Shiyo had been in the mafia, she seemed just as normal as Kyoko and Haru, in fact, a little more normal than Haru.

Back up at the roof, the battle's participants were moving so fast that no normal eye could perceive their specific movements. All that could be seen were small glints of light: the glint of their tonfas and their hair, the shining of the sun as it witnessed their battle. As they moved forward and bounced back again, they left afterimages. Shiyo's golden hair whipped through the air, wrapping around her face temporarily whenever she stopped moving. Hibari's dark eyes were sharp and cold, gleaming malignantly whenever they clashed.

Without skipping a beat, Shiyo gave a small laugh and told the skylark, "If this keeps going we'll destroy the whole of Namimori, never mind the school. It's only been 5 minutes and we've already left our mark all over the roof."

It was true. Small nicks and burn marks were spattered across the roof. The thought seemed to stay Hibari's frenzy for just a moment. They landed nimbly on their feet on either side of the roof, watching each other warily.

"You're strong." Hibari said, sounding slightly excited, though he showed no sign of it.

"Why thank you." Shiyo said cockily, "I think a falcon should be able to match a skylark."

Hibari's eyes narrowed, "Falcon?"

She smiled and nodded, "Mmhmm. A falcon. I know you're still new to the mafia and won't even acknowledge the fact that you are part of one, but in the mafia, I'm known as the freelancer assassin..."

In one of his many secret hideouts in the school, Reborn said, musingly, "Falco d'Argento. The Silver Falcon."
