"Everyone quiet! First period there will be a free period because of a staff meeting."

All the students immediately got out of their desks and did their own thing by talking with their friends, reading a book and other things they want to do on their free time. Some of the students stood around Kiyomi's desk as they were talking with her.

"Free periods are great." One of the female students said.

"Seriously…I could use the time to relax." One of the male students added.

"Couldn't agree more." Kiyomi said with a smile, causing everyone around her to blush at the sight of her smile.

"So pretty." All the student sighed in bliss.

"Stop!" A familiar voice shouted outside the classroom.

Out of curiosity, Kiyomi excused herself from the students around her desk and walked over to the closed door. Once she slid the door open, she stepped leaned her head forward to see what the commotion was.

Suddenly, I-Pin ran across the hall with smoke trailing behind her. Shortly after, Tsuna, Gokudera and Yamamoto ran after her with Lambo and Ryohei following behind them.

"What's going on now?" Kiyomi wondered before she looked back in her classroom and said, "I'm going to step for a bit. Be right back." She closed the door and followed after everyone. "Wait up, you guys!"

She and everyone attempted to catch I-Pin but she kept dodging them as they practically ran through all the hallways and stairs. Suddenly, I-Pin quickly opened one of the windows and jumped out.

Both Tsuna and Ryohei looked out the window to see I-Pin up the air. "She went to the roof." Ryohei stated.

"Let's go then." Kiyomi said as she and everyone ran down the hallway.

"There she is!" Kiyomi and everyone else made it to the roof and found I-Pin standing on top of the water tower.

"Give back the 10th's lunch!" Gokudera shouted.

"Wait a sec, Gokudera." Kiyomi said before she pointed at I-Pin's hands. "Look what's in her hands." In each of I-Pin's hands were two bento lunches with the same lime green wrappings. "There's two identical bentos?"

"What does this mean?" Gokudera asked.

"One of them is Tsuna's lunch that I brought over." Lambo said proudly.

"Then, what's the other one?" Tsuna asked.

"Job…Nitroglycerin." I-Pin answered.

"It's that thing that'll explode even with a small force." Ryohei stated once he figured out what it was.

"What is she doing with something that dangerous?!" Kiyomi exclaimed with widen eyes in fear of everyone's safety.

Yamamoto laughed and said, "And we don't know which one's which."

"Don't be so indifferent!" Tsuna exclaimed.

"If that much nitro explodes, this school will be destroyed." Gokudera stated.

Kiyomi noticed I-Pin was having a hard time trying to figure out which of the bentos was hers and which one is Tsuna's. "I-Pin, you have to make sure you know which one's which!" She shouted with encouragement.

Lambo laughed as he fell on his back and pointed at I-Pin. "You're starting to get confused! You're so stupid, Tail-Head!"

"Lambo! That's not a nice thing to say!" Kiyomi scolded.

"Aah!" Kiyomi turned back at Tsuna and I-Pin who was started to sweat. "That's not good…!" She said.

"The countdown of the Pinzu Time-bomb is starting!" Tsuna shouted while holding his head. Sure enough, I-Pin head glowed to reveal the Mahjong countdown.

"What the hell did you do?!" Gokudera growled as he was picking on Lambo.

"Would you knock that off?!" Kiyomi shouted as she pulled the crying Lambo away from Gokudera. "We've got more important things to worry about."

"Oh, no…" Tsuna stared at I-Pin in fear as the countdown began. "If there's a huge explosion caused by a huge explosion…"

"It'll be an extreme and huge explosion!" Ryohei finished with a grin on his face and arms crossed on his chest.

"Seems pretty amazing." Yamamoto agreed.

"Hey, where'd I-Pin go?" Kiyomi asked when she noticed I-Pin isn't on the water tower anymore.

"Oh…right." Everyone turned towards Tsuna to see I-Pin latched herself onto his leg and her countdown has now three Mahjong pieces. "When it starts counting down, she clings to people because of her shyness." Tsuna ran around trying to get I-Pin to let go of his leg. "Someone do something! Save me!"

"10th!"

Suddenly, something hit Tsuna on the forehead which caused him to fall down on his back. Seconds later, he shot back up in his boxers and a familiar flame on his head. "REBORN!"

"Thank you, Reborn." Kiyomi whispered before she noticed something hit Tsuna on his right shoulder. "What was that?"

Tsuna grabbed a hold of I-Pin's head and pulled her off of his leg. "I'll throw with my dying will!" Tsuna shouted before he threw her up the air and away from the school, leaving everyone to sigh in relief.

"As expected of the 10th!" Gokudera praised as he, Yamamoto and Kiyomi ran up towards him.

"She sure did fly far." Yamamoto said before he noticed something in the air. "Something's falling." Everyone looked up to see one of the bentos was falling down from the sky.

"I-Pin dropped one." Kiyomi stated.

"If that's the one with the nitro…" Yamamoto trailed off.

"The End of school?"

"Huh?" The flame on Tsuna's head died out, returning Tsuna back to normal. "Oh no! The Dying Will died out! What should we do?"

Without even thinking, Kiyomi shoved Lambo into Gokudera's arms as she shouted, "Hold him!" She ran up to the fence and jumped up to the edge.

"Kiyomi!" All of the boys cried out.

She ignored their cries as her eyes followed the descending bento. Once the bento fell to her level, she jumped off of the fence and lunged herself to grabbed the bento. Once secured in her hands, she tucked her body and performed a double front flip as she was falling. As she was getting closer to the ground from her second flip, she untucked herself and straighten her legs out before landing on her feet and down on her knees for a safer landing.

"That was too close." Kiyomi sighed in relief as she stood up straight.

"Kiyomi!" She looked up at the roof to see the boys looking down at her with amazement and relief. "That was awesome, Kiyomi!" Tsuna shouted.

"Nice catch, Kiyomi!" Ryohei added.

Kiyomi just smiled and said, "Thank goodness."

Once Tsuna put on a fresh school uniform, he and the others met up with Kiyomi outside of the school who was sitting at a bench.

"Kiyomi, that was amazing!" Gokudera complimented.

"Where'd you learn to do that?" Yamamoto asked.

"Oh, well I used to do gymnastics when I was kid." Kiyomi said.

"You competed?" Ryohei asked.

"I used to, but now I just do it to keep myself limber." Kiyomi held up the bento and said, "But enough about that. Why don't see what's really inside this bento?"

The boys nodded before they gathered around her as she slowly untied the wrapping.

"Fingers crossed that this is the safe one." Kiyomi muttered before she took off the bento lid to reveal a homemade lunch. "Ooh, that's a cute lunch." She commented.

"Yeah! That's the lunch that I brought over!" Lambo cheered while jumping up in the air.

"So…" Kiyomi turned her head towards Tsuna who dropped his head in despair. "I used my dying will…to save this embarrassing lunch?"

A sweat drop appeared on Kiyomi's head as she said, "Now, now. At least the school is safe from the nitro. Isn't that a good thing?"

The following day, Kiyomi was watering the flowers around the school as she was humming a tune.

"So you're the one." Kiyomi blinked a couple of times before she looked over her shoulders to see Hibari wearing a opened black Gakuran with a red inner lining and the red committee armband pinned to the left sleeve resting over his shoulders.

"Hibari-san?" Kiyomi turned around and gave him her full attention. "Is there something I can do for?"

"I was curious to see who's been planting these flowers around the school." Hibari said as he looked around the area to see various flowers such as daisies and chrysanthemums of various colors. He could tell right away that the flowers were being well taken care of.

"Yes, I've been planting and watering these plants since I'm part of the Garden Club. Is that a problem?" Kiyomi asked with a tilt of her head.

"Hmph…" Hibari turned around and walked a few steps forward before he stopped and asked, "By the way, do you know about a commotion that went on in the roof yesterday?"

Kiyomi froze up a bit before she calmed herself and turned her attention back to the flowers. "I didn't know there was something going in the roof."

"Hmm…Is that so?" Hibari looked over his shoulders and asked, "You wouldn't be lying to me, would you?"

"Now what do I have to gain by lying?" Kiyomi asked as she looked back at him over her shoulder.

Silence filled the area between the two of them before Hibari turned his head back and walked away.

"Phew…" Kiyomi let out a breath of relief.

"That was close." Kiyomi looked down to see Reborn standing by her feet admiring the flowers. "These are quite lovely."

"Reborn. Thanks, but what are you doing here?"

"I came to deliver a message from Tsuna."

Kiyomi blinked a couple of time before she asked, "A message?"

Reborn nodded his head before he looked up at her and said, "He wants to see you by the gym equipment shed after school."

"Did he say why?"

"He just said that it was very important. Don't be late." Reborn said before walking away.

"Why do I get the feeling that Reborn is up to something again?"

Turns out Kiyomi was right to believe that Reborn was up to something since she wasn't the only one who showed up to the location. Standing beside her was Yamamoto, Ryohei and Gokudera with Tsuna standing in front of them.

"What is it, 10th?" Gokudera asked.

"Have you finally decided to join the boxing club, Sawada?" Ryohei asked.

"I was called her by that kid." Yamamoto said.

"So did I." Kiyomi added.

"So it's these members again." Tsuna muttered.

"Again?" Kiyomi repeated with a tilt of her head.

"Is something wrong, Tsuna?" Reborn asked while he was dressed in a panda costume while sitting in a tire swing. Bianchi was with him too and she was dressed as a large squirrel.

'Okay, that's cute.' Kiyomi thought to herself with a giggle.

"What's with the costumes?! And what is that rope attached to?" Tsuna wondered as he looked up to see that the rope continued way up in the sky and who knows how far. Tsuna let his last question slide before he looked down at Reborn and asked, "Hey, weren't you going to introduce a babysitter for Lambo?"

"They've already been introduced. As a boss, you'll choose one from your Family. Obviously." Reborn stated.

Lambo's laughter was heard as he opened a window from an empty classroom and jumped out on the edge of the window. "Lambo-san, who magnificently completed his first errand, appears!" Lambo announced.

"Don't try to act cool. You're the one who leaked in front of everyone." Gokudera stated.

"T-That's not true! I just peed a little!" Lambo argued. "Don't try to fool me, stupid!" He teased while pulling his left lower eyelid down and sticking his tongue out.

"You bastard! It looks like you don't get it unless it's pounded into you!" Gokudera growled with an anime vein on his forehead.

"Oh, what's that?" Lambo pointed off the side. Gokudera stopped and looked at where he was pointing at, only to see nothing. Suddenly, Lambo jumped on his head and began stomping on it. "Stupid!"

"Gah" Gokudera got madder before he kicked Lambo off of his head. "Die, you bastard!" He glared down at Lambo and shouted, "Do you want me to beat you into a steakhouse?!"

"Gotta…be…calm…I can't!" Lambo shouted as he cried his eyes out.

"They're so passionate. What a great atmosphere." Ryohei commented.

"How is that great?!" Kiyomi shouted with a harden glare.

"Are you all ready?" Bianchi asked as she held a stop watch and a clipboard.

Gokudera turned his attention towards Bianchi as he finally noticed her. "Big Sis?"

Kiyomi turned towards Gokudera and asked, "Gokudera, how's your stomach?"

"My stomach doesn't hurt…"

"What does that mean?" Tsuna asked.

"If I don't see her face, I'm fine." Gokudera confirmed with a smile.

"I guess that's one way of doing it." Kiyomi said while scratching her cheek with an index finger.

"Then, let's start the test." Reborn announced.

"A test?"

"For?"

"What?"

"A test to see who is better suited to be a babysitter for Lambo." Reborn replied.

"A babysitter for Lambo?" The boys, minus Tsuna, and Kiyomi repeated.

"I refused to be a babysitter for him. I hate him." Gokudera declared.

'Like we haven't known that already.' Kiyomi thought to herself.

"I'm fine. So what game is it today?" Yamamoto asked.

'Of course he would make it into a game.' Kiyomi thought with a sweat drop on her head.

"By the way, whoever is the babysitter will become the Boss's right hand man." Reborn announced.

"R-Right hand man?" Gokudera was left flabbergasted.

"That would be nice." Yamamoto said with a laugh.

"I don't care if it's left or right. Whatever, but I'll be passionate!" Ryohei declared with a few jabs of his fists.

Gokudera got up close to Tsuna and painfully said, "I-I really love Lambo."

"That's not very convincing." Kiyomi said, but Gokudera ignored her.

"The rules are simple. The one who makes Lambo smile first is the winner." Reborn explained as Lambo started to cry harder.

"I'll start." Gokudera stated before walking up to Lambo.

"You have three minutes." Reborn said.

"Okay, start." Bianchi started the stop watch as everyone watched to see how Gokudera was going to make Lambo smile.

Gokudera looked like he was about ready to snap until he held out his hand towards Lambo and said, "Hey, sorry about before." Lambo stopped crying and stared at Gokudera's hand. "Let's make up. Handshake."

Just as it looked like Lambo was going to accept the handshake, Lambo dropped a hand grenade in Gokudera's hand and pulled the pin off before jumping off of the window and onto the ground.

"What the hell?!" Gokudera shouted before he quickly threw the grenade into the bushes just seconds before it exploded. Out of anger, he started to pick on Lambo, causing him to cry once again. "You really piss me off!"

Yamamoto quickly held Gokudera back while Kiyomi snatched the crying Lambo out of his hands and shouted, "Knock it off!"

"Calm down. Gokudera." Yamamoto said with a smile.

"Get away from him." Ryohei ordered.

"Let me go, Yamamoto!" Gokudera demanded as he tried to get out of Yamamoto's grip.

"That's why I said…"Tsuna trailed off.

"Okay, time's up. Hayato, you're disqualified." Bianchi announced, snapping Gokudera out of his anger.

"Oh crap…" He muttered.

"Okay, I'm next." Ryohei stated as Kiyomi placed Lambo back on the ground and stepped back.

Ryohei stood over Lambo who looked up at him to see Ryohei's face looks very intimidating and scary. "Smile."

"Eh?" Lambo just stared at his face.

"Sm-i-le. Smile, damn it!" Ryohei shouted, causing tears to build up in Lambo's eyes. "Smile!"

"I'm scared!" Lambo cried.

"Smile! I said smile!" Ryohei shouted.

"That's not gonna work either…" Kiyomi groaned as she placed her hand on her head.

"Okay, three minutes. Disqualified." Bianchi announced.

"Next is Yamamoto." Reborn announced.

"Okay." Yamamoto stepped forward.

"The best has arrived." Reborn stated.

"Yamamoto looks like he's good with kids." Kiyomi said with Tsuna agreeing with her.

"We'll see how he plans to get Lambo."

Yamamoto kneeled down at Lambo with a baseball glove on one hand and a baseball in his other hand. "Have you ever played catch?" Yamamoto asked with a kind smile.

Lambo responded with a shake of head saying 'no'.

"You catch the ball in this glove." Yamamoto explained as he demonstrated to Lambo who looked interested.

"Catch?"

"Of course, playing catch! Great thinking Yamamoto! And Lambo seems interested, too." Tsuna praised as everyone watched Lambo getting used to wearing a baseball glove while Yamamoto was standing on the other side with the baseball and another baseball glove.

"Okay, I'll start." Suddenly Yamamoto narrowed his eyes and threw one of his fast balls at Lambo. Unfortunately, the ball hit Lambo in the face which caused him to fly backward until his body came in contact with the shed.

"Lambo!" Kiyomi ran towards Lambo and the boys following her from behind.

"Sorry!" Yamamoto shouted.

Everyone surrounded Lambo who fell off the crater his body created from the shed and onto the ground.

"Yamamoto, what the heck was that?!" Kiyomi shouted with a glare in her eyes

"Sorry. When I get into the baseball mood, I can't control myself." Yamamoto said while rubbing the back of his head in embarrassment.

"That's what a sportsman is like." Ryohei agreed.

"What the hell?" Tsuna muttered as Lambo cried once more.

"I didn't know Yamamoto had such a scary side to him." Kiyomi thought out loud.

"He finally did something good." Gokudera said with a satisfying smile and arms crossed.

"That only leaves Kiyomi to participate." Bianchi stated.

"What is this?" Everyone snapped their heads forward to see a glaring Haru.

"Haru-chan?"

"You're all making Lambo-chan cry. Tsuna-san too. What are you doing?" Haru demanded.

"Well…There's a reason for this…"

"You're horrible." Haru cut off Tsuna before she kneeled down to the crying Lambo. "Lambo-chan, are you okay? Don't cry."

Lambo immediately stopped crying and said, "Yeah."

"She's most fit to be a babysitter." Reborn stated.

"That's true." Tsuna agreed.

"Does that mean she's the 10th right hand man?" Gokudera asked.

"Of course that's what you care about." Kiyomi said with narrowed eyes.

Haru stood up with Lambo in her arms and said, "To make such a sweet child cry…" Without knowing, Haru was putting pressure with her grip on Lambo causing him to scream in pain. "Even if it's Tsuna-san, I won't forgive you!"

"Haru-chan, ease up on your grip!" Kiyomi exclaimed.

Lambo pulled himself out of Haru's grip and landed back on the ground before he pulled out his bazooka from his hair.

"The 10 year bazooka!" Tsuna exclaimed.

"Seems like he lost his sense with the pain." Reborn said.

"Can you really blame him?" Kiyomi asked as Lambo jumped into the bazooka.

"Lambo-chan, what is it?" Haru ran up towards the bazooka.

"Haru-chan, don't do near that!" Kiyomi ran towards Haru and pushed her away before the bazooka shot and covered Kiyomi with a big pink dust cloud. Once the dust cloud cleared up, it revealed Kiyomi standing in front of Adult Lambo who was smiling down at her with his hands on her shoulders.

"Adult Lambo!" Tsuna called out.

"Hi there, Adult Lambo. It's good to see you again." Kiyomi greeted with a smile.

"It's good to see you too, Kiyomi-chan." Adult Lambo greeted back with a nod of his head.

"Hahi! Who is he?! He's so pervy!" Haru screeched.

Adult Lambo looked at Haru and said, "It's me, Haru-san."

"Hahi! Who are you?!" Haru cried out in fear before running off. "He's so pervy! Don't come near me!"

"I guess Haru can't take Adult Lambo." Tsuna said.

"If Adult Lambo is no good, then Haru is out, too." Gokudera stated with a smile.

"Romeo!" Everyone turned towards Bianchi who was staring at Adult Lambo through her squirrel costume's eyes.

"Uh oh…I forgot that Bianchi thinks Adult Lambo is her ex-boyfriend." Kiyomi said with a scared tone in her voice.

"I see you've come." Bianchi took off the upper part of her costume to reveal a glaring Bianchi spinning what looks like a purple dough. "Poison pizza! Magic cutter!" Seeing Bianchi's face caused Gokudera to fall down from his stomach pain. Suddenly parts of the trees and windows were sliced by Bianchi's poison cooking as it was getting bigger as Bianchi was spinning it. "Romeo! I won't let you get away! Take your hands off of Kiyomi!"

Adult Lambo quickly removed his hands from Kiyomi's shoulder and took a couple of steps back before running off. "Excuse me."

"Adult Lambo is always so pathetic." Tsuna stated as everyone watched Adult Lambo run away.

"He forgot a horn. I'll throw it." Kiyomi turned towards Yamamoto to see him about to throw the cow horn at Adult Lambo. She quickly grabbed his wrist and shouted, "Don't even think about it! I'll return it to him."

Kiyomi took the horn before running after Adult Lambo. "Adult Lambo!" She called out.

Adult Lambo stopped and turned around to see Kiyomi running towards him. "Kiyomi-chan."

Kiyomi stopped in front of him and handed him his horn. "Here, you dropped this when you ran off."

"Thank you, Kiyomi-chan." Adult Lambo smiled as he accepted the horn. "My set wouldn't be complete without this."

"I figured. Take good care of it." Kiyomi said with a smile back.

"Unbelievable…" Tsuna muttered with widen eyes as he and his friends watched the scene in front of them.

"That's Kiyomi for ya." Yamamoto said.

Suddenly, Reborn appeared besides Tsuna on his tire swing, catching Tsuna off guard. "Reborn. Really, how is that attached to anything?"

"It looks like Kiyomi's the one to care for Lambo." Reborn stated.

"I bet you knew that from the start!" Tsuna shouted.

"W-Wait!" Everyone turned towards Gokudera who was still on the ground in pain. "D-Does that mean Kiyomi is going to be the 10th's right hand man?"

"Why would I want that?" Everyone turned to see Kiyomi walking back to them.

"Kiyomi. Where's Adult Lambo?" Tsuna asked.

"I told him to run off to get away from Bianchi until his five minutes are up. Anyway, I don't want to take that title away from Gokudera. You deserve it more than anything."

"Kiyomi…" Tears were building up in Gokudera's eyes.

"In any case, Tsuna, if you needed someone to watch Lambo why didn't you just ask me? I don't mind watching him or I-Pin." Kiyomi stated.

"Are you sure? You've seen how much of a handful he is." Tsuna said.

"If I could handle my Ototo-san when he was five, I'm pretty sure I can handle Lambo and I-Pin."

"It's decided! Kiyomi is Lambo's babysitter!" Reborn announced.

"I'm home." Tsuna announced.

"Please excuse me."

"Hi!"

"Pardon the intrusion."

"I'm so tired. That was a horrible day." Tsuna groaned as he entered into the living room with Gokudera, Yamamoto and Kiyomi following him in.

"Tsu-kun." Everyone turned their attention to Nana in the kitchen. "You forgot your lunch again today. A kind person brought it back." Nana showed a familiar person sitting at the kitchen table.

"Oh, Madam, that's to be expected from anyone." The person turned around to reveal it be Shamal.

"Doctor Shamal."

Kiyomi quickly hid behind Gokudera and whispered, "Gokudera, please keep him away from me unless I'm sick or dying."

"Hey, that's…!" Everyone turned to Tsuna who was pointed a certain bento box that Shamal was holding.

"It was hanging from a tree in your yard." Shamal said while gently shaking the bento causing Tsuna and his friends to freak out.

"So that means…The nitro!" Tsuna and his friends exclaimed.

"It sounds kind of strange for a lunch. What's inside?" Shamal asked as he continued to shake the bento.

"Aah! Stop shaking it!"
