short backstory: Okay so this is my very first fanfiction and will probably be my only fanfiction for a while since i've invested so much time into this so far. In it you will see a well rounded mix of Vocaloids and UTAUs with Arikusandoria and Mitsumori being the two main characters(this is the story of how Mitsumori ultimately awakens Arikusandoria's slumbering heart system in short). I made Ariku and Mitsumori so yeah, this is kinda the story that explains their existence and stuff and how they just adjust to life in general with the other Vocaloids and UTAU's

I hope you enjoy it^^

Ch1- The Dawn of a New Day

Someday Ariku-chan, you'll be all mine. Someday.

Mitsumori adjusted his glasses as he turned the page in the novel he was reading as he sat in the library. "...so I'll see you in choir practice Ari-chan? I'm glad you decided to join!" It was not so much the voice that caught Mitsumori's attention as it was the name that was said.

"Ari..."

The name echoed in his head. A giggle was heard followed by a, "M-most definitely Len-kun!" Highly curious, Mitsumori had shut his book and looked about for the girl he hid his feelings from daily- a slender purple-haired girl with golden eyes that shined so brightly, even behind her studious glasses. Gosh, she's so pretty. He thought, looking over her outfit which consisted of the typical school girl uniform but for some reason, it just seemed more appealing on Ariku, her long legs made the skirt seem much shorter, though it was normal length, the way she walked with such cute shyness was irresistibly adorable. Though he did not look at her with perverted intentions, the thought did tease him a bit.

"Oh, um, hello Mitsu-san. I see you found a new book to read. Is it any good?"
Startled, Mitsumori jumped slightly. "Huh? Oh why yes Ariku-chan, I am pleased with this book so far. But I just started reading it like 16 minutes ago so... not an accurate assessment haha." The statement came out sounding oh so geeky and Mitsu was laughing nervously, hoping Ariku didn't think he was a nerd or loser. A smile gave him relief. "Well that's good! I was hoping you had found it, because I knew you had wanted to read the next part already." A small pause made Mitsu wonder what she was thinking about, as it appeared she was going to speak again. After a moment, she shook her head. "Um...uh anyway Mitsumori, this school is so nice huh? A lot different from my hometown that's for sure." She continued. "Yeah, it's a change from mine as well."

Ariku and Mitsumori had been childhood friends since the day he moved to her old school. Once they met at UTAU Academy, the pair became instant friends, but had now been transferred to the Vocaloid Institute for a reason neither knew.

A look of worry crossed Ariku's face.

"Hm? Everything okay Ari-chan?" "...I-I just hope the Vocaloids don't find out we're UTAU's... I-I don't want to be bullied again..." She said softly, rubbing her arm. Mitsumori's expression softened and he stood and place a hand on her shoulder. "Everyone seems nice here Ariku-chan, but if you're truly that worried, we'll just sing outside of school together. That way no one has to know our secret." A weak smile crossed her face. "Haha...If only I hadn't joined choir... They'll find out today Mitsu-san. I-I'm nervous." "Well that Len fellow seemed like an okay kind of guy, maybe it won't be too bad." Mitsumori replied, trying to reassure her. She seemed to accept this. "..Yeah that's true. Thanks Mitsumori!" Ariku hugged him, causing him to blush slightly. 'Arikusandoria smells sweet.' He thought. "Y-you're welcome Ari-chan. I h-hope you have a good day." He replied with pink cheeks. She let go and smiled. "Don't be late for class okay?" Once Ariku had left, Mitsumori went over what happened in his head.
Gosh, I sound like a teacher, always so dorky and junk... Why can't I use normal words around her? He thought to himself.

...Ariku hugged me so tightly...But I'm sure I'm just a friend to her.

"Do Re Mi Fa So La Ti Do!" The chorus of Vocaloid teens was warming up. "S-sorry I am late Sensei!" Ariku cried, bursting through the choir hall doors. Huffing, she slowly gathered herself and to her embarrassment, everyone was just staring at her.

"Is that the new Vocaloid girl we got? Hasn't she been here like a month already though?"

"Yeah I think."

"She's adorable."

"Hmph, she's late."

Uneasy by what was being whispered, Ariku became more nervous as she fidgeted. "Ah...um...-"
"Please, take a stand on the risers, Miss Sanaka." A silver haired woman said politely. "Yes mam." Ariku replied softly, taking a spot in what she guessed was the Alto1 section.
'To them, it really doesn't matter where they stand or what they sing... they can sing whatever they want and sound amazing. But me... No, I can't let them find out I'm not one of them. If only Mitsumori were here, he could help hide the notes I don't sing well...' Ariku thought with a sigh.
"Len... is that the girl you were telling me about?" A girl asked the blonde.
"Hmm? ...Oh YEAH! Hi Ariku-chan!" Len called out happily, waving to the girl.
"LEN, stop being disruptive! We are about to start!" The teacher snapped.
"Yes Yowane-sensei..." The boy pouted and looked down although Ariku had smiled over at him and mouthed "Hello.", making him smile again.
"Now, why don't we start off with reading new music, just to see how good we all are at sight reading on the spot?"
Music was passed around the choir and they commenced to sing on the spot the foreign piece in their hands. 'So far so good' Ariku thought. 'Nothing too high or low for anyone to notice.'

But her relief instantly vanished, for on the next page was a stream of significantly higher melodies and harmonies. 'Oh gosh, they're bound to hear my out of tune frequencies now!' She thought miserably. Little did she know the bell was going to ring soon. Sensing something was wrong, Len raised his hand right as the chorus was supposed to hit their high octaves. Haku sighed but stopped the choir. "What is it Kagamine?"

"Uh... um... what is this for exactly?"
"We are just reading it, I'm trying to see if we need to sight read more or move straight into vocal technique."
'Any second now...Come on and ring already you stupid bell!' Ariku thought, catching on to what Len was trying to do.
"And um... what do you think? Cause I sure as heck think we sound pretty awesome, right Rin?" Len said, addressing his twin sister to back him up.
"Um, yeah! We sound fantastic Yowane-sensei! Please don't make us sight read!"
It was visibly evident that Haku was getting quite frustrated as she just put a hand to her head.

DING!

An exasperated sigh. "Freaking' idiots..." she muttered. "Just ah...just get the heck outta here!"
