The boy with light brown spikey hair quickly slid the door to the side.

"You're late Sawada!" The teacher scolded.

"S-Sumimasen[1]!" He stuttered. As he crossed into the classroom he tripped in thin air. Just as he was about to fall to the ground a hand shot out and caught him. He was pulled back to his feet by the back of his collar.

He turned around to thank the person but when he turned around he saw a girl with long very dark brown hair, which almost looked black. Her eyes were the color of the shadows with a tint of color to them. As everyone looked, she kept on a passive face, though Tsuna caught a flicker in her eyes as she stared back at him.

She opened her mouth as if to say something, though shut it after a moment of thought. She looked around the classroom and her eyes seemed to have scanned the classroom.

"Th-Thank you." He finally managed out.

She turned her head towards him and opened her mouth slightly, "Pr..." then shut it, and looked to the teacher who had finally stepped in.

"Sawada! Get to your seat!" The teacher shouted. Tsuna quickly made a beeline for his desk, and at the same time, the teacher walked towards the girl.

"I'm sorry for the trouble." She just silently shook her head. "Is there anything you need? I don't remember getting any new students in this class."

"Please excuse me for bothering your class, but I'm actually a third-year student and I got a little lost." She bowed a little in apology.

As the teacher gave her directions to her classroom, Gokudera leaned over to Tsuna. "Jyuudaime[2]. Do you know her?" He asked curiously.

Tsuna quickly shook his head. "No."

"How about before you leave, you at least introduce yourself to my class. That way if any of my students see you, they can help you around the school." The teacher said gathering most of the student's attention. He pushed her towards the front of the class room. After long pause and a gesture from the teacher she spoke. Her face and voice devoid of any emotion.

"I'm Rin. Nice to meet you." She bowed, and as she stood back up a girl raised her hand. Rin awkwardly stood there waiting for the girl to ask her question. She finally gave a small nod to the girl.

"Do you have a last name?"

"It's just Rin, please." Then she turned and left the classroom.

"Did you know that girl Tsuna?" This time it was Yamamoto who asked it. They were walking to the public pool together.

"If you can't swim 15 meters, you're going to be practicing kicks with the girls team!" The teacher threatened and then laughed.

Tsuna was horrified, but Yamamoto said they could practice at the public pool. Tsuna was instantly relived.

"No. I've never seen her in my life before… Well, maybe… She did kind of look familiar." Tsuna was in deep thought.

"What was that she said to you when she saw you? Pr?" Yamamoto thought about it.

"Yeah, it was Pr and then she stopped." Tsuna also thought about what she was going to say.

"Maybe she knew you couldn't swim and she was going to say practice!" Yamamoto said with a smile.

"No way! There's no way she could have known that!" Tsuna shouted, embarrassed.

"Prince of Vongola." A small voice came out of now where. Tsuna looked around but saw no one. Then up on Yamamoto's head.

"Reborn! I told you! I'm not a mafia boss!" Tsuna shouted at him. "And there's no way that she's involved with mafia!"

"And over here is the extreme boxing club." Ryohei pointed towards his boxing club. "Is there anything else you would like to see?" He asked the girl standing next to him.

"No, I think that's good enough." She shook her head.

"Oh! How about I show you the town of Namimori?" He asked Rin as the sudden thought came to him.

"No, I really do think that's enough." She really thought she had enough, though the boy was kind, he was too energetic for her.

"Sensei said to show you around so I will show you around to the extreme!" He pumped his fists into the air, at the same time his phone rang. Rin watched as he nodded to the person on the other end. "Right, I'll be right there." Then he quickly grabbed her hand and dragged her across to Namimori's public pool.

Throughout the whole way, Rin's face was impassive.

When they made it there, he threw Rin into the women's locker room as he went into the men's.

"Should I leave him…?" She thought to herself as she stood in the room. Instead she grabbed a towel and walked out into the pool area with her school uniform on. There she saw him waiting, and she followed him across to another area where she saw the three boys in the class she disrupted, along with another girl.

"Seems like it's my turn!" He shouted making his entrance. "Leave everything to me!"

"Kyoko-chans big brother!" Tsuna exclaimed, and then look to the girl standing next to him. "T-The girl from this morning!?"

"Oh! You already know her? Good! No need for introductions. Sawada!" He then went on explaining how to become good in sports and what not.

Tsuna started walking to the edge of the pool to get out, but all of a sudden got a cramp in his foot. Ryohei jumped in to 'save' him, though his swimming was a bit… off.

Rin couldn't help but stare and say one word. "Weird." She then dumped her towel on a nearby chair and left the public pool while no one was looking except for the beady black eyes of an Arcobaleno.

The next day at school. Rin heard kids talking about Tsuna in the girl's swimming pool.

It was lunch time and Rin was just stepping out of her class when she heard her name. She looked left to find a girl with brown hair running and waving to her. The girl was followed by another with darker hair, the one she saw at the pool yesterday. They stopped in front of Rin.

Rin stared them down. They didn't seem to know that she didn't recognize them.

Rin finally sighed. "What?"

"Ah. Sorry. I haven't introduced myself. I'm Sasagawa Kyoko. I'm Ryohei's sister. I was in the second-year class that you visited on your first day."

"Nice to meet you."

Kyoko then turned to the girl next to her. "And this is Miura Haru. She goes to Midori Middle School."

"I-I see." Rin was starting to wonder what business they had with her, as well as why a girl from another school came over. "I'm Rin…"

"Rin-san, after school today, we're going to the beach and then the festival tonight. We were just wondering if you could come with us."

"… Thank you, but no." She simply replied and was about to walk away.

"Hahi?! Why?" Haru spoke up.

Rin tried to come up with an excuse. "Well, I don't know you two very well."

"Yes, but my brother says you too are good friends." Kyoko said innocently. "And he asked us to invite you since you're new to the school."

"…" When Rin didn't say anything to that, Kyoko continued on.

"Are you sure you can't come?" When she asked that, Rin swore she saw the lights brighten and bubbles start to form around her. She didn't seem like she was begging, or that she didn't mind Rin couldn't come at all. But there was something else.

Rin sighed once more finally giving in. "No. I can come."

"Really?" Kyoko asked a little surprised. She turned to Haru and they both cheered.

Rin watched carefully at the guys who were focusing their attention on Kyoko and Haru as they walked by. The two girls were wearing their swimsuits as they walked across the beach towards Tsuna and his friends. Rin walked behind them in white capris along with a black T-shirt covered over with a black and white plaid shirt.

"Sorry to keep you waiting!" Kyoko announced. At the sound of her voice, Rin stopped and turned her head forwards so that she wouldn't run into the two.

"We're done changing!" Haru said.

Past the two, she could see the boy Sasagawa Ryohei had called Sawada yesterday and the other two who were also at the pool. Sawada was blushing as he saw Kyoko and Haru, and then quickly snapped out of it as he saw Rin behind them.

"R-Rin-san!" He was clearly surprised to see her there.

She just nodded her head. "Sawada-san…" Her voice trailed off and she looked towards Gokudera and Yamamoto.

Gokudera, who was mistaking it for a glare started to yell at her. "Well?! Are you going to say something or not?!"

Tsuna who was just starting to figure out the situation finally introduced them. "R-Rin-san, this is Gokudera and Yamamoto…" He gestured to the two. One was angrily glaring at her while the other just smiled and waved.

Yamamoto had gotten back to putting the umbrella up. "So, Sasagawa's brother works part-time here?"

Kyoko had nodded. "A senior who's a life guard asked him to help."

"Wow, a life guard! That's so cool!" Tsuna seemed greatly impressed. "Wait, so our part-time is being a life guard?"

Gokudera had turned his head in confusion. "Tenth, didn't you know?"

Tsuna just shook his head. "Reborn said we'd be working on the beach."

"There you guys are!" Ryohei's voice could be heard next to them. They turned their heads in the general direction. "With my lion-strength and fish-like agility, I'm going to become an apprentice lifeguard!" He had announced.

Gokudera was shocked. "You expect to save someone with your swimming abilities?!"

Ignoring the comment he turned his head towards Kyoko, Haru, and Rin. "Oh! Thanks Kyoko, for bringing Rin here!"

Rin's eye had twitched slightly. He had said her name informally.

"Let me introduce you to my co-workers, but first, here's Pao Pao-Sensei who is being beaten by the heat." Ryohei had announced too quickly. Rin looked over and quickly looked away. She could have sworn 'Pao Pao' was looking straight at her. The Arcobaleno though, had switched his eyes to Tsuna after she turned away. "And then…" Ryohei scouted for his co-workers.

"Hey! Don't litter! That only creates more work for us!" Everyone turned their heads to find three guys bullying a boy who had apparently thrown his trash on the ground. They held him up by his shirt.

Rin had taken a step forward, but stopped herself. The guy threw the kid down and started walking over towards them.

"These are my senior lifeguards!" Ryohei introduced. "They are former Namimori Middle School Boxing Club members.

The smug looking one in the middle walked towards Kyoko. "Are you Ryohei's little sister?"

"H-Hello." Kyoko had tried to be polite, though he moved his head down, and closer to her.

"You're just my type!"

Rin glanced at Ryohei, who apparently didn't mind that his sister was getting hit on by his senpai… It was either that, or he just couldn't tell.

The two other guys that were behind him went next to Haru.

"We'll keep these girls company." Said the one with Kyoko.

"You guys keep watch on the beach!" Said another.

The smug one was about to place his hand down on Kyoko's shoulder but another hand had smacked it away, grabbing Kyoko and pulling her back as well as Haru.

The two girls were pulled back by Rin.

The seniors stepped up to Rin and looked her up and down. Rin pushed the two girls behind her as they tried to intimidate her. "Who do you think you are?" He asked her. As he kept her busy, the other two went for Kyoko and Haru.

"You make crappy deals." Rin had said in a monotone voice. Just as the other two were going to get Kyoko and Haru, Gokudera and Yamamoto stepped up.

"She's right, why the hell do we have to work for you?" Gokudera had agreed with her.

"I invited them to have fun, not to be lifeguards." Ryohei had stepped in finally, defending his friends.

"You don't understand, we just want to teach you and your friends how wonderful it is to be a lifeguard."

Lies. Went through everyone's mind except for one.

"Oh, I see." Ryohei nodded.

Gokudera was shocked though. "Don't agree!"

Kyoko stepped out from behind Rin a little. "Then, I'll help my brother out."

Haru had also stepped out. "We're going to stay with Tsuna."

Rin looked at the two girls, and then looked back to the boy known as Sawada Tsunayoshi. What could Haru see in the small frightened boy in the back? She had just sighed and turned her attention back to the problem at hand.

"Three against three, swimming race. Losers will be slaves to the winners." The guy had challenged.

Everyone was very much shocked to this challenge and were about to protest, except it was muffled by a punch from Reborn, or 'Pao Pao'. Rin just manage to block the punch right in front of her face in time, though she saw him smirk before he answered for everyone else. "We accept the challenge."

"Then it's decided."

"What the hell are you doing?" Tsuna held his head in his hands as he messed up his hair.

The challenge consisted of swimming towards an island and looping around it and back. It was a 2 out of 3 match.

Yamamoto had volunteered to go first, and Gokudera decided for Tsuna that he should go last. So the order went as. Ryohei offered to take Tsuna's place, but as Rin and the rest had seen back in the public pool. There was no chance.

Though it seemed like Tsuna didn't want to swim either and without knowing it, turned to Rin.

She lightly shook her head and crossed her arms. Tsuna then looked to her attire and remembered she wasn't wearing any swim wear.

Kyoko and Haru appeared in his line of vision. "We'll cheer for you!" Kyoko smiled as Haru agreed.

Just as the race started, the two were even, though Yamamoto gained speed and was ahead. Looking from the corner of her eye, Rin couldn't help but notice that the two 'lifeguards' didn't seem fazed. As the two swimmers disappeared out of sight, only one came back and it sure wasn't Yamamoto.

As Gokudera went, the two were tied. Haru and Kyoko happily cheered him on. Though in the end, it was the same results as before.

Though they had lost, they were given one more chance with Tsuna. Who in the middle was going to save a child that had been washed away by the waves. Just as he made it, he started sinking and Rin ran into the salty ocean waters. Though stopped when the water was above her ankle and she saw Tsuna splashing up and out of the water with a dying will flame on his forehead. She turned her head in the direction on the lifeguards when she heard them talk about lowerclassmen.

"You mean these lowerclassmen?" She heard the familiar voice, and saw Gokudera and Yamamoto standing around a bunch of beat up students.

Tsuna punched the other lifeguard and safely brought back the little girl.

Haru turned her head around. "Hahi? Rin-san, you still haven't put your yukata on?"

"Don't tell me?! You don't know how to put a yukata on?" Kyoko looked a little shocked, though that wasn't the point. She didn't want to wear the yukata, she would rather wear what she was wearing now, which was what she wore not too long ago at the beach.

She looked down at the dark fabric. It was a nightly blue color with flowers at the bottom corner that weren't too bright except for one bright orange-yellow one. The obi was a deep dark blue but it had a different tint than the night color.

"Well, we can help you with that!" Haru mistook Rin's silence as a yes to Kyoko's question.

Rin quickly shook her head, embarrassed slightly to have been caught blanking off. "It's not that." She said almost silently. "I just haven't worn one in such a long time…" Her voice trailed off as she stared at the clothing with a look. Though it was not one of sadness, it was more of a reminiscing stare to Kyoko and Haru.

The two girls just looked at each other and smiled, then went over to the third-year student who was blanking off once more and started helping her dress up to her small mumbled protests.

The three walked to where they saw Tsuna and everyone else, with Rin taking up the rear.

"A choco banana please!" Haru and Kyoko had called out announcing, their arrival.

"Haru! Kyoko-chan! A-And Rin-san!" Tsuna had stuttered when he came to her name again. Was it so surprising?

"Wow! You have a stall?" Kyoko asked in an amazed voice.

Tsuna had blushed. "Yeah." He nodded his head.

Haru though had looked slightly disappointed. "We wanted to see the fireworks together with everyone." Kyoko's smile had fallen a little when her friend mentioned that.

The three walked past Tsuna who was muttering something about fireworks to get their chocolate bananas from Gokudera.

"Good luck!" Haru waved.

"See you." Kyoko smiled at them.

Rin took up the rear once more while eating her choco banana.

"Isn't this a little too much, even for Hibari-san!" Tsuna was surrounded by the robbers, who were actually the lowerclassmen and the lifeguards from before.

As the sound of a bullet went off, he fell as if he were dead. Then came back with the dying will flame on his head. "Reborn! Fight as if I were to die!" He shouted very loudly.

"They're only two junior high kids! Attack them!"

And just as they were about to make their moves, the sound of explosions could be heard and from the smoke came Yamamoto and Gokudera.

"Jyuudaime!" Gokudera held his dynamites at ready.

"Support has arrived!" While Yamamoto was holding a bat.

With that, the dangerous battle began with Tsuna, Hibari, Gokudera, and Yamamoto. Without anyone knowing though, a dark figure was watching from the shadows.

"Hey!" A voice called from the steps that lead up to the shrine they were at.

"Tsuna-san!" The voices were clearly Haru and Kyoko who were running up with Lambo and I-Pin, Rin was walking behind them.

Just as they made it to the top, fireworks exploded behind them. Quickly, they went to sit near Tsuna, Gokudera and Yamamoto. Rin watched standing behind the group. Though Tsuna turned around and caught her eye. He smiled kindly and gestured to the spot next to him. Rin hesitated for a long moment before sitting next to him and behind Haru.

She looked up and stared at the fireworks until there was none left. Then when they were over, she stood up and left without saying a word.

[1] - Excuse me

[2] - Tenth

Sorry if something doesn't make sense and the fact that it's rushed at the end...
