Author's Note: Hello, Beautiful People!

So, there's a funny story behind this fanfic, but before I tell it, I'm going to let y'all know this fanfic is actually a prequel to The Monster Club, a fanfic on Kate's account K. A. Farron. Now before you click away, you do NOT need to read The Monster Club to understand and enjoy Hyper Piper. This story here can be read independently - you will not need to read The Monster Club before or after reading Hyper Piper (but it'd be cool if you did, just throwing that out there).

Now that's out of the way, the funny story. For those of you who don't know, The Monster Club is cowritten by Kate and me. It's a fanfic we have been working on for years and have put so much love and effort into. The Monster Club is one of my favorite stories. Then one day I got an idea - what if there was more to a secondary character's story than initially thought?

When I wrote Hyper Piper two years ago (yes, there is a two-year gap between being written and published), I simply dubbed it a fanfic of Kate's and my fanfic. That's what it was, after all! I wrote it for fun without the intents on making it canon, and I did show it to Kate while I was writing it, but that was it.

However, eventually we started discussing making Hyper Piper canon to The Monster Club universe. We talked on and off about if for a long time (half the reason there was a two-year gap between writing and publishing), and we eventually agreed that Hyper Piper was canon. Good thing for you guys too, or else I wouldn't be publishing it!

Anyway, I asked my dear friend Kate to write the opening and closing chapters in Rin's perspective for this story (if you haven't read The Monster Club, her intro chapter will give you a good idea of the world the characters live in). My chapters will be in Nero's POV. Like The Monster Club, a lot of love and effort went into this story. It's our hope you love our characters half as much as we do!

Chapter 01: Introduction ~ Rin

Everyone's probably heard of my brother by now. He's that snarky, British kid with a bad temper who thinks he can get together with my current best friend. You know him? Of course you do, who doesn't know him?

I'm Rin, and I'm his twin sister.

You're not here to hear about his story, you're here to hear about mine. Or not mine, really. Actually, it is. It's confusing.

Basically, don't be under the impression that I'm going to be the one telling the story; I'm the one introducing it. The person who will be telling this story is going to be Nero, the bumbling idiot who somehow managed to become my friend. But it still is my story, really. I mean it's all about me, I'm just not the narrator.

Right, so enough fourth wall breaking, let's get down to business.

My brother and I used to live in Britain, which was awesome, and a lot of fun... For me at least.

I had everything I needed. My best friends, Dex and Daina, were absolutely awesome and we'd get up to mischief all the time. Never went a day we spent apart. My mum was awesome too. She was the person we'd inherited our Monster side. She was a single mum, always busy, but somehow managed to make time for me. I'll admit I was a pretty spoiled child. I had good friends, a good family, a good school, good everything. There was nothing for me to worry about.

But Len was a different story. I don't really understand how it works myself since I'm no biologist (Len's the smart one out of the two of us, I'm more creative), but there's this gene that gets passed down through our species, and it affects him in ways it doesn't affect me. He gets grouchy and has a really bad temper. Back in Britain he only ever got into fights, and he never had friends to back him up. Even Mum didn't get along with him. He insists she hates him, but I do try to tell him she still loves him, he's just a pain.

Of course he doesn't listen. It didn't help that Mum decided to send him off to America to live with our aunt.

"She's sending me away," Len grumbled as he sat on his bed, knees tucked up to his chest. I was sat next to him, doing my best to comfort him.

I really do love him more than anything in the world, and I'm like 85% sure he feels the same about me, but we'd never been the closest of siblings - even now - so comforting him was hard. It was the first time I'd seen him cry in years. Tears just kept rolling and rolling down his cheeks and I kept trying to dab them away, but more kept coming.

"I'll go with you," I told him, giving him my widest smile.

"You will?" He looked up, his eyes still red and poofy. It wasn't a good look for him, really. "But you can't come with me, you have a life here. You have your friends, and Mum, and everything else. I have nothing, I don't belong here."

"We're twins, we belong with each other," I told him. "I'll go anywhere with you."

Even now I'm not sure if I regret saying those words.

I had been convinced that America would be awesome, and that I'd make lots of friends like I had back in England. I was pretty popular back there, everyone loved my happy, bubbly personality. But in America it wasn't the same.

Len and I joined our new school a year after everyone else had started. By then everyone had set up their own friendship groups so it was hard to find somewhere to fit in. I tried to be my normal, happy self, but people just turned their nose up at me, as if being happy was a sin.

Thankfully, our uncle worked in the Monster business. Monsters, for those who don't know, are people who aren't human. Either they're another species entirely, like werewolves, or they have magical powers, like the ability to manipulate time. Whatever it is, we're all Monsters, and we have to live in secret. Our Uncle Al works with trying to make life for Monsters easier. It was through him we were introduced to this robot kid named Piko, so we at least knew someone at school who was like us.

Piko was a great guy, but I didn't hit off with him immediately. I was homesick, longing for Dex and Daina. Len, however, hit it off instantly with Piko, so much so you'd expect the two of them to start dating. I simply sat there and smiled, glad that my idiot brother had finally found a friend.

I tried to keep up to date with Len, but he always ignored me in favour of Piko. I didn't blame him, I didn't always pay attention to him back in Britain, but it did kinda hurt that I was constantly flooded over. Still, I told myself I'd find a friend and everything would be okay.

But it wasn't.

I'm not gonna lie; watching Len grow more and more popular was hard, and it hurt. He'd started off being friends with only Piko, and the robot girl Piko would hang out with called Miki. I didn't want to risk snatching his friends away so I simply stayed away. After our new after school club was set up, courtesy of Len himself, he started to hang out with the local vampire too. Kaito, the vampire, was surprisingly popular in his year, and so this got Len into the 'cool' crowd. It's funny, because Akaito, Kaito's older brother, was one of my bullies for some time.

Len will always have a 'bad' reputation at this school. Within the first week he'd gotten into a fight, and he was known as a trouble maker, but apparently the girls liked that. I tried even more to get his attention, now I had no fear of taking his friends away from him, but he was pretty much blind to me. We kept drifting further and further apart, and I couldn't help but wonder if I even had a brother.

And that was when I met Nero.

The first time I remember meeting him wasn't exactly graceful. I was tucked away in a janitor's closest, bawling my eyes out. See, I told you. Not graceful.

You see, half way through the year everything had gotten too much. I had no friends, practically no brother, and constantly had to deal with looks and displeasing stares from all the other kids at school. I hated it, absolutely hated it, and the thing I hated even more was that I knew Len had put up with this for nearly sixteen years, and for me it had only been a few months. His misery came out in temper tantrums and broken noses, mine came as floods of very unattractive tears.

Hyper Piper, that's what the kids called me. Apparently I had too much energy, and so they all teased me for it. No one ever called me by my proper name, they probably didn't even KNOW my proper name. I was only ever called Hyper Piper or the Kagamine Girl or Len's Sister.

So here I was, crying in the janitor's office, trying to get out all my biking up misery before I went back to class. It was best to cry and get it all over with. My knees were tucked up to my chest and my head was buried between them, and I hated how I was just another kid crying in the janitor's closet.

Suddenly the door opened and I looked up with wide eyes. A blond haired, gold eyed boy stood there, staring at me. Through my tears I at first thought it was Len, but I quickly realised it wasn't.

"Are you all right?" he asked, and he went a little rigid as I stared back.

I didn't say anything and just leapt to my feet. I shoved him out of the way and sprinted off down the hall, ignoring his calls for me to come back. I couldn't have anyone see me at my weakest. I couldn't have anyone know how I truly felt.

I'd say more, but I should probably leave it there. Nero has the rest of the story but that pretty much some's up our first meeting.

So I'm Rin and this is my story about how I met my new guy best friend. You may have heard about all my brother's hardships, but this is about mine, and the hardships of the bumbling idiot who thought it was a good idea to make friends with the least popular girl in school.
