Hibari Katana: The Second Skylark

Prologue

Yamamoto Takeshi was quietly humming as he sprinted to school. It was a normal day as usual, and Yamamoto had left the shop early so he could practice his batting before school. As he turned a corner he ran into a raven-haired girl.

"Look out!" But it was too late. They tumbled into each other, the girl hitting her head hard on a nearby wall.

"That—" She winced "—really hurt." She rubbed her head where it was hurt.

"Ah, my bad. Are you okay?" He asked as he helped her up. "Oh, by the way, I'm Yamamoto Takeshi. You are?"

"Hibari—"She stumbled. "—Katana."

"Hibari Katana? Sounds a lot like Hibari-san's name. Then, can I call you Katana?" He gave her a once over. She wore a black dress shirt, the sleeves folded up to her elbows, and a white button up vest over it. The upturned collar revealed a black and white chess pattern on the inside, a white skirt, and knee-high heeled boots, one black one white. She also had a black dog tag around her neck."I haven't seen you before. Are you new? What school are you from?"

She nodded, her head throbbing immensely. "I'm a transfer student…to Namimori Middle." At that she fainted from the pain of her throbbing head.

"Oi! Are you okay? Katana? Tch. I guess it can't be helped." He picked up their bags and carried her princess style as he hurried down to the school. Guess I won't be able to practice this morning. Ah well. He looked down at her sleeping face. She's cute… He thought, smiling warmly at the thought. He held up one of her hands. Her fingers were long and thin. A ring on her ring finger. Such a pretty face.

Chapter 1

"Yo! Tsuna!" A tall male would holler at a shorter male with spiky brunet hair, who was walking through the front gates of Namimori Middle.

"Oh, hey Yamamoto-san." Tsuna would reply, turning around to wait for his friend. He and Yamamoto had become friends through Tsuna's tutor, Reborn. Yamamoto was the star athlete of Namimori. Tall, friendly, smart, and good-looking, Yamamoto Takeshi was popular with both the girls and guys at school.

A lot unlike me. he thought.

"What's up Tsuna? Oh," Yamamoto said as he neared his friend. "Where's Gokuderra?"

"Who knows? He didn't come this morning. By the way Yamamoto when did you get here?" Tsuna asked.

Gokuderra was both his and Tsuna's friend, even though he often denied to being Yamamoto's friend. A transfer student from Italy, Gokuderra came to Namimori Middle on Reborn's word. The silver haired teen often considered himself to be Tsuna's "right hand", and also was the bearer of the Storm Vongola ring, like Yamamoto, who bore the Rain Vongola ring, and Tsuna, who had the Sky ring in check.

"Oh, well you see when I was walking this morning—" He started.

Gokuderra approached the two from the crowd. "Boss!" he yelled.

Grinning at their friend, the dark haired boy would pat Gokuderra on his back, as a greeting, as the silver haired boy shot him a look a combination of dislike and disapproval.

"Good morning, Gokuderra-kun." Tsuna'd say, at the exact moment that a small man dressed in a black suit and hat, a green chameleon sitting at the rim, hopped up onto Yamamoto's shoulder.

"Ciao-su." He said.

"Morning Reborn." The threesome chorused as they entered their classroom, just in time for the bell to ring.

"Everybody sit down!" The teacher faced the class as everyone sat down. "I'd like to announce that we've gotten a transfer student today." He paused as everyone in the room looked at the opening door. "Class, this Hibari Katana. She will be joining this class as of now."

Eh? Hibari…Don't tell me, she's related to Hibari-san! Tsuna thought as they watched the door with anticipation. A young female with waist-long, raven black hair appeared and stood at the front of the class. She had dark almond-shaped eyes, but they were the same as Hibari Kyoya. Slit-like and piercing. Yamamoto's eyes widened at the sight of the new student as he recognized her face.

She woke up as he carried her through the gate. "Eh, what the—Oi Yamamoto! Why are you carrying me like this?" She flushed as she noticed several students watching them.

He stopped walking. "Well because you fainted. I couldn't leave you lying on the ground outside." He said with an innocent look on his face.

"Still you didn't have to carry me like…like this! Let me down I'm fine! Honest!"

"You shouldn't lie about being hurt you know."

"I got it I got it but still can you let me down now?"

"Hahaha, no way~."

"Hey!" She struggled out of Yamamoto's grip, but caused both of them to fall. "Ah, sorry. I, uh, have to go now!" She grabbed her bag and left without another word.

"Nice to meet you all. I'm Hibari Katana. I was currently studying abroad in Italy and just recently came back. I hope we'll get along fabulously.

Yamamoto jumped out of his seat. "Katana-san! You're in this class?"

She looked over at him. "You're….Ah! Yamamoto Takeshi!"

The door slammed open. "H-Hi-Hibari-san!" This time it was Tsuna who jumped in surprise.

Hibari walked towards Katana. And held out an item in his hand. It was a chess checkered cell phone, with a small, purple shaped cloud bell hooked at the top. "Katana, you forgot this at home."

"Ah, oh yeah. Sorry, Aniki." With that she took It and placed it in her back pocket."Thanks." He nodded and left the room. As the class burst into conversation. She's Hibari Kyoya's sister? How scary.

Katana faltered slightly as Yamamoto came to her rescue. "Oi oi! Just because she's Hibari's sister, doesn't mean she's like him, right?" He said with a smile as his fellow classmates nodded in agreement amongst themselves. Katana thanked him, and sat down in her seat. She sat near the window side, next to Yamamoto's seat. The class seemed to go by in just a few minutes. By the time she realized the time, it was lunch. She picked up her bento and dropped a small folded note on Yamamoto's desk as she headed up to the roof.
