The next day, Kiyomi's mother dropped Kiyomi off in front of the school just like yesterday. After Kiyomi closed the door, she walked up to the driver's seat and looked at her mother who rolled down her window.

"Now, Kiyomi, are you sure that you want to walk to school from now on?" She asked.

Kiyomi smiled and nodded. "Yeah. I just want you to take Hatsuharu to school. I'm a big girl now, mother."

Saiyuri smiled back and said, "All right. If that is what you wish, Koneko. I love you."

Kiyomi leaned down and kissed her mother on the cheek. "Love you too. But sometimes I wish you and dad would stop calling me 'Koneko'. I'm too old for that."

"No matter how old you or your siblings get, you four will always be our little boys and girls." She said before she drove away.

Hatsuharu rolled down his window and stuck his head out. "See ya later, sis!" He shouted with a wave. Kiyomi waved back before walking inside the school.

When she arrived in the schools' shoe locker, she noticed Tsuna and Kyoko. "Good morning, Tsuna." She greeted, causing Tsuna and Kyoko to turn and see Kioymi standing behind Kyoko.

"Good morning, Kiyomi." Tsuna greeted.

"Hello, my name is Kyoko Sasagawa. Please to meet you." Kyoko introduced herself with a bow.

Kiyomi bowed and said, "My name is Kiyomi Nakamura. Nice to meet you."

Kyoko smiled before she turned to Tsuna and asked, "Did you know that our class is getting a transfer student today?"

"Th-That's right…It was in Reborn's notebook." Tsuna said.

'Reborn?' Kiyomi thought with one of her eyebrows risen up. 'Is he a friend of Tsuna?'

"I wonder what they're like. Think it'll be a boy? Or a girl?" Kyoko wondered.

"N-no clue…" Tsuna stuttered, catching Kiyomi's attention.

'Well, well, looks like Tsuna got a thing Kyoko.' She thought with a grin that could rival the Cheshire Cat's smile.

After the bell rang for class to go on a lunch break, Kiyomi decided to go visit Tsuna in his class. She asked a couple of students and they were kind enough to show her where it was, even though they were shocked that she wanted to see him.

She arrived to see a boy with tanned skin, spiky black hair, and light brown eyes talking to Tsuna. "We're counting on you today, Tsuna." The boy said with a smile.

"Counting on me?" Tsuna wondered.

"In the volleyball match." A different boy said.

"You're on the volleyball team?" Tsuna asked the tanned boy.

"He's on the baseball team, but he's good at other sports too."

"You've been so amazing recently, you've caught everyone's eye. We're counting on you today. Use some of that last-ditch power." Yamamoto said.

"Well, but that was…" Tsuna tried to explain what happened with yesterday's situation.

"Yeah. You were really cool back there, Tsuna-kun." Kyoko said, grabbing Tsuna's attention.

"People stopped calling you 'No good Tsuna' after that." A girl beside Kyoko stated.

"Now that you mention it…" Tsuna agreed.

"Do your best. I'll be cheering for you." Kyoko said with a smile.

"As will I." Kiyomi said as she walked up to the group, grabbing the blushing boys' attention in the process. "I know you're gonna do great, Tsuna."

Tsuna nodded. "Y-Yeah, you can count on me."

Kiyomi smiled before she felt someone staring at her direction. She turned her eyes to her left and saw a boy with silver hair glaring at Tsuna.

'Is that the new transfer student?' Kiyomi wondered.

"So, who are you?" The tanned boy asked Kiyomi, grabbing her attention away from the transfer student.

"I'm Kiyomi Nakamura. It's nice to meet you." She introduced herself.

"I'm Takashi Yamamoto. Nice to meet you too."

Kiyomi was waiting inside the gym where the volleyball tournament was being held. She was amongst the many students that were waiting for Tsuna.

The door opened to reveal Tsuna in his gym clothes. He was surprised to see everyone cheering him on to win the tournament. They were even calling him the 'team's secret weapon'.

Kiyomi walked up to where Kyoko and her friend, Hana, were at to see Tsuna. "Tsuna-kun, do your best!" Kyoko cheered.

"You're gonna do great, Tsuna!" Kiyomi cheered as Tsuna walked past them.

Kiyomi couldn't help but notice that Tsuna was acting a bit nervous and also noticed that the silver haired boy was in the team.

"We will now begin the match against Class 1-A and Class 1-C!" An instructor announced. Everyone who was playing in the tournament got in their place as everyone else stood to side.

As soon as the whistle went off, the volleyball was the throwing the air and they game began.

While the game was progressing, Kiyomi was amazed to see Yamamoto playing very well in volleyball. 'I'm impressed. I bet he's really good at baseball just like everyone said.' She thought to herself.

Tsuna, however, wasn't doing so well. Whenever the ball was coming his way, he would either miss it or get hit by it.

After the first set had ended, Kiyomi heard some shouting coming from Tsuna's team.

"Are you really trying, Tsuna?"

"If you're just playing around, then leave!"

"We're playing, seriously!"

Tsuna rubbed the back of his head as he said, "U-Uh…I-I actually sprained my ankle in the match with Mochida-senpai…"

Just when Kiyomi was about to walk towards them, she noticed that Tsuna had a serious look on his face as he walked back to the game.

"Something's different about him." Kiyomi mumbled to herself before she heard a gun go off. She turned to the sound of the gun and was surprised to see a baby wearing a suit and a fedora while holding a gun. 'What the…'

"Here!" A shout broke Kiyomi's train of thought and brought her attention back to the game.

The ball was heading towards Tsuna again. He jumped up so high in the air that he shocked everyone, he even surprised everyone when he blocked the ball with his…um…where the sun don't shine.

Kiyomi hissed. "That really gotta hurt."

From then on, Tsuna's team had won three sets in a row with everyone cheering Tsuna on.

"Wow, thanks to Tsuna's enthusiasm, the team is working together!" Kyoko exclaimed.

A whistle went off again. "Game set! Class 1-A wins!" Everyone cheered for Tsuna for his and the team's victory.

Kiyomi smiled and said to herself, "I knew you could do it, Tsuna." She noticed that the silver haired boy and Tsuna walked out of the building, which got her curious and decided to follow them.

Kiyomi followed the boys to the back of the school and stood at the corner of the building.

"Wh-What do you want, Gokudera-kun?" Tsuna asked.

"It'll be the end of the Vongola Family if they name scum like you the new boss." The boy, Gokudera, said.

"The 10th? Vongola family?" Kiyomi wondered.

"W-Why do you know about the family?" Tsuna asked.

"You're an eyesore." Gokudera pulled out two pairs of dynamite. "Die."

"D-Dynamite?!" Tsuna shouted as Kiyomi's eyes widen.

"That was sooner than I expected." A voice said. Everyone looked around until a part of the tree opened up to reveal the same baby Kiyomi saw inside the tree.

"Reborn! In a place like that…" Tsuna said.

"That's Reborn?!" Kiyomi whispered.

"It's another one of my hideaways." Reborn said before jumping on top of Tsuna's head. "Gokudera Hayato."

"What?! You know him?" Tsuna asked.

"Yup, he's a family member that I called over from Italy." Reborn said.

"You're in the Mafia, Gokudera-kun?" Tsuna asked.

"Mafia? What in the world is Tsuna up to?" Kiyomi wondered.

"It's our first time meeting though." Reborn added.

"So you're the hitman that the 9th has the most trust in, Reborn. I've heard stories about you." Gokudera said.

'There's just one surprise after the next.' Kiyomi thought to herself with a sweat drop on the side of her head.

"It better be true that I'm becoming the 10th if I get rid of this guy." Gokudera stated.

"Wh-What are you-" Tsuna was cut off by Reborn. "Yup, it's true."

"What?! Can you even do that? Was it a lie that I'm destined to be the 10th?!" Tsuna shouted.

"If you don't want to die, fight."

"F-Fight? You're kidding. I can't fight against a Mafia guy!" Tsuna shouted before running away with Reborn jumping off of his head.

However, Tsuna was stopped by a dynamite which blew up and stopped Tsuna on his tracks. He was on his knees, whimpering in fear with Gokudera standing behind with a few more dynamites in his hands. "Stop right there."

Tsuna turned towards him. "W-Where did that…?"

"It's said that Gokudera Hayato can hide bombs in any part of his body, in other words he's a human bomb." Reborn explained.

"My other name is Hurricane Bomb Hayato." Gokudera added. "Prepare yourself."

Kiyomi's eyes widen with the dynamites were suddenly lit on their own. "Wow…is that possible…" But she stopped herself as she followed Tsuna and Gokudera.

Kiyomi followed them until they stopped at the other side of the school and she stood to the side.

"I'll finish you with the next one." Gokudera got his dynamites ready.

"Hey, Tsuna." A voice called. Tsuna turned to see Yamamoto walking towards him and Kiyomi. "Y-Yamamoto, Kiyomi?!"

Yamamoto noticed Kiyomi and asked, "Kiyomi, what are you doing over here?" Before she could say anything, Gokudera threw the dynamites at their direction.

Tsuna screeched and jumped, "I have to extinguish them!" He tried to put them out with his bare hands but got slightly burned in the process. "T-This won't work!" Tsuna exclaimed.

"What game is this?" Yamamoto wondered with a lite dynamite in his hand. "It looks like fun! Let me in too!"

Kiyomi gasped and shouted, "Yamamoto, get rid of that!"

"REBORN!" Tsuna shouted. Kiyomi turned to see Tsuna in his boxers and a flame on his head. 'Talk about déjà vu.' She thought with a sweat drop on her head.

"Extinguishing fires with my dying will!" Tsuna shouted before he put out the fire with his bare hands again, this time he was moving fast and wasn't complaining about his hands being burnt.

"Double bombs!" Gokudera shouted as more of his dynamites were thrown. But that didn't stop Tsuna from putting them out.

"Triple bombs." Gokudera said before one of his dynamites fell from his hands and landed by his feet. "Oh, crap."

Kiyomi gasped when all of Gokudera's dynamites fell to the ground around him. Without a second thought, she ran towards him. "Look out!" She pushed Gokudera and herself away from the dynamites as Tsuna put them out in the nick of time.

Tsuna was back to his normal self as Kiyomi got off of Gokudera. "Thank goodness…" Kiyomi sighed in relief.

Suddenly, Gokudera was on his hands and knees and kneeled before Tsuna, surprising him and Kiyomi. "I apologize! You are indeed worthy as the next boss." Gokudera looked up with a different look on his face. He was smiling. "10th, I will follow you to the ends of the earth. Your wish is my command"

"The loser serves the winner. It's our family code." Reborn explained.

"Code?" Kiyomi and Tsuna wondered.

"Actually, I never had any intention to become the 10th. I just wanted to test your abilities to see if you're strong enough." Gokudera explained.

"Gokudera-kun."

"But I was a fool! You've exceeded my expectations." Gokudera turned to Kiyomi." You even risked your life to save me, even though I was yours' and the 10th enemy!" He turned back to Tsuna. "I, Hayato Gokudera, place my life in your hands!"

"Hold on, I can't handle that! Can't we just be classmates?" Tsuna asked.

"I won't let you do that." Gokudera said with a glare.

"Well done, Tsuna." Everyone turned to Reborn. "It's because of your strength that Gokudera became your subordinate. You've passed for today." He said before he pulled out a book and wrote something inside. "And you didn't need the Dying Will Bullet."

Yamamoto laughed as he put an arm around Tsuna's shoulders, causing Gokudera to have an angry vein on the back of his head. "Tsuna, you're really such a funny guy! Let me into the group too." Yamamoto said, causing Tsuna to look at him confused. "You're the boss, right?"

"Hey you!" Everyone turned towards Gokudera who stood up on feet. "Don't get so friendly with the 10th!"

"Huh, what's up with him?" A voice asked. Everyone turned to the side to see three school punks standing off to the side.

"That underwear guy is such a loser!" Another one said before all three of them laughed.

"T-The third year delinquents…!" Tsuna said,

"I'll take care of them." Kiyomi said as she stood up with a glare on her face.

"What?!" She slowly started to walk towards them while cracking her knuckles.

"Wait! You'll get hurt, Kiyomi!" Tsuna exclaimed but she didn't listen.

"Don't worry about her, Tsuna." Reborn said. "She knows what she is doing."

Tsuna was confused. "Huh?"

The three delinquents stopped laughing when Kiyomi was getting closer to them. "Well, well, if it isn't Princess Kiyomi. What, you came to play with us, doll?"

Kiyomi's eyes widen. "Doll?!"

The delinquents started to laugh again before one of them was punched in the stomach, knocking him unconscious in the process. The other two stopped laughing and glared at her.

"So, you want to play rough, huh?" Before the other two could do anything, Kiyomi punched one of them in the face while elbowing the other one in the stomach.

The one that was punched in the face fell on his back, grabbing his face in pain and groaned while his friend was on his stomach unconscious.

The boy moved his hands from his face as Kiyomi stood over him with her hands on her hips. She smiled and said, "Here's a little tip for the future: Don't ever call me doll." She blew her bangs away from her eyes before stomping her foot on his stomach, making him go unconscious as well.

She turned around and walked back towards her friends and laughed when everyone but Reborn had their eyes widen and their mouths wide open.

"You might want to close those mouths, boys. It might attract flies." She joked before they did what she said.

"Kiyomi, that was amazing!" Tsuna exclaimed.

"Yeah, where did you learn how to fight like that?" Yamamoto asked.

"I went to an All-Girls Karate class after school back in my home town. My parents thought that it would be best if I learned how to defend myself. Glad it came in handy." Kiyomi explained.

"We could use someone like you in the family." Reborn said.

Kiyomi looked down at Reborn and asked, "Why would you want me in your family? What is the Vongola family anyway?"

"The Vongola family is a mafia family from Italy. Tsuna is going to be the next boss of the family when he is done with his tutoring with me." Reborn explained.

"Reborn, don't bring Kiyomi into this!" Tsuna exclaimed. "Besides, she's not interesting in this, are you Kiyomi?" He asked.

"Actually, I am." Kiyomi said, shocking Tsuna. "HUH?!"

"I think it would be fun and it's the kind of excitement that I've been looking for ever since I moved here." Kiyomi said with a smile.

"HUH?! WHAT KIND OF ANSWER IS THAT?!"
