Part one :
It was a normal day.
… Perhaps normal was an understatement.
It was a boring day. It started boring, with usual actions, and usual bugging from his sisters, and as expected it stayed boring until the very end.
Like usual, the black haired middle schooler named Orihara Izaya went home after school, of course after doing his usual habit of finding people's data. Unfortunately nothing interesting happened that day, and so he went home in a quite bad mood.
Human had always been unpredictable.
Things like heart, love, emotion, and other silly what-nots interfered too much to their judgments, and so for him who (at some level) always think objectively, other people had always been intriguing. Always different, always unexpected, and that's why he loved people.
Other people but his family members.
They were all boring, in his opinion. His mother, father and two sisters for some odd reason always did what he expected. Not only that, the reasons behind them were also predictable. It got into his nerves how they never faltered. They're so human, yet somehow inhuman in his eyes.
Unfortunately that day, the rest of human beings seemed to resemble his family so.
He entered his house like usual, both of his parents were out somewhere. His sisters were supposed to be in the house, but they weren't at the living room playing games, or at the backyard and judging from the lack of light on their room, they were most definitely not in there too.
The lack of noise certainly mean they were not in the bathroom.
… That means…
Izaya sighed at the revelation.
The only place left they could be at that moment was none other than his room.
He rushed upstairs and opened the door with a bang, surprising the two children that were reading on his bed. The long haired one, Mairu, fell from the bed while Kururi merely jolted and stared wide eyed at her brother.
"What are you girls doing here?"
"Reading."
Both answered in unison.
Izaya sighed once more, his hands on his hips and his head shaken. "I wonder why you decided to do it in my room… Even though here I'm envying you who have the widest most comfortable room in this house. Ha, should we trade then?" he said with a hint of sarcasm as he unbuttoned his black uniform, revealing red t-shirt underneath. After that he proceeded to put his bag on the table and sat on the swivel chair.
Mairu grinned as she climbed to the bed, while Kururi smiled.
It was then that Izaya realized the book on Mairu's hand.
"… Mairu… what's that on your hand?"
Her grin got wider as she said proudly, "Porn magazine!"
Kururi nodded. On her hand was also porn magazine.
After a heartbeat, Kururi added, "Brother's... bed... (Izaya Onii-sama's. We found them under your bed)"
"It's nothing to be ashamed of, Iza-nii! I always think that normal boy should have at least one of these! Why, if you find a boy who doesn't have one you can be almost sure that he's gay! Though I certainly don't have problem with gay people. I myself had this revelation today at school after I accidentally on purpose pinned Kuru-nee and kissed her on the lips! I love Kuru-nee!"
"… naughty…"
Izaya certainly couldn't believe his ears. That morning the two of them were still normal first grader. Too normal that they were almost invisible. Kururi still talked normally with voice loud enough to hear, and Mairu certainly did not speak that much.
And he was sure that in the morning they had no interest at all in porn. It's even questionable if they knew what porn was then.
"Okay. As much as I'm glad with your revelation and your amusing opinion about me and porn, who are you and what have you done to my sisters?"
Even though he said this, it's hard to hide the Cheshire like grin that was now plastered on his face.
Kururi was the one who answered, "… Evil… family (How rude. We're really your sisters.)"
"True true! How rude, Iza-nii! It was you who said that we're boring because we're too quiet and invisible, and honestly I don't get why you called us invisible when we're certainly not transparent!" Mairu puffed her cheeks in annoyance.
That morning, Izaya had said to the two twin girls the following statement.
"You two are too boring."
And really, for Kururi and Mairu, it was as if thunder had stroke in broad day light. It was too shocking to hear.
"O... Onii-chan... what do you mean?" Mairu trembled slightly, and it was felt by Kururi. The elder sister's grip on the others hand got tightened.
"Didn't you hear me? You too are boring. You have the same personality, same figure, same ability. How freaking boring!" The older boy turned and grinned. His eyes were narrowed, and to the two girls he looked somewhat like a demon.
Yes, the way his red eyes seemed to be twinkling was very demonic.
"You're worthless. There are thousands, no, millions of twins like you in Japan alone! And yet, you use the boring fact that you're twins as 'cute-factor'? Don't make me laugh."
What the two girls did was normal. They wore their newly bought matching jackets and ran hand in hand to their beloved brother. The hoodies had cat ears on them, and people all said that they're so cute in it.
Izaya's reaction was unexpected, to say the least.
"What? Can't say anything in response? See? This is why you two are..."
"Tell us what we should do."
Perhaps because she realized that her twin was already crying, Kururi braved herself to ask her brother. Izaya folded his hands, ooh-ed as he's a bit impressed with Kururi.
"What you should do? Why do I have to tell you girls that? What's in it for me?"
"..."
"As I thought."
Little did Izaya know that his action then would change their very lives.
That morning, this conversation happened as the two children walked together to their school.
"Kururi Onee-chan... Onii-chan hates us, doesn't he?"
The older twin shook her head. "No. Of course not. Onii-chan is just in a bad mood today."
"But, Onee-chan... Isn't that because we're boring as he said?"
"... No. I don't think so."
Kururi only said that to calm her sister, and Mairu knew it.
They then walked in silence until the school became visible. Mairu kept her head down, managing to walk without run into anything because Kururi held her hand and walked on the side closer to the street.
Kururi couldn't take it.
She stopped suddenly and said...
"Mairu-chan. If you're still bothered, I have an idea. It'll be hard to do, but I'm sure Onii-chan will be happy if we do it."
"We just have to be different. Right now, our hairstyle is the only thing that makes us different. So, we just have to accentuate our contrast even more. If we're different, I'm sure Onii-chan would not call us boring anymore."
Mairu blinked and tilted her head to the side. "A... accentuate?"
"... to make clear."
Her mouth then formed a plump O as she nodded in understanding. "I see... I understand. Let's do it, Onee-chan! So, what should we do?"
Looking her sister already full of spirit once more, Kururi walked again, a contented smile plastered on her pretty face. Mairu followed her like a lost puppy.
"Mairu-chan, why do you like that pair from RPG game we played?"
"Well, they're funny and interesting."
"And why are they funny and interesting?"
"Because they're so synced, they could be one person. Even though their personalities are..."
Kururi smiled when Mairu paused. It seemed like she understood.
"The complete opposite... Onee-chan, you're a genius!"
Mairu jumped and hugged her sister as she laughed in delight. People around them gave them odd looks, but the two were too focused on their plan to please their brother to pay attention. They ran to their class and sat on their usual spot at the back near the window.
"Nice jacket, Orihara!"
One boy shouted from across the room. Indeed, for some odd reason they had their hoodies on, and the matching cat ears managed to make them look cuter than usual, just as everyone said the day before. They flashed identical smiles to the boy and said thank you.
No one knew who the boy was praising.
None cared. They both looked equally eye-catching.
The twins didn't care too. They sat down and started to plan out their transformation. Even if the whole world said they were cute and lovely, it wasn't enough until their brother said so.
Izaya was... their beloved.
"Okay, first, let's list the traits out. I think our look shouldn't be our priority, though put it down as reminder."
"Right! We must fix our act first!"
"... and besides... I like being called your twin. I don't want to forget that."
"Hehe, Onee-chan, what are you saying? We're not twins, right?"
Mairu laughed as she wrote the traits of her favorite hero with her sloppy handwriting. Her sister had already forgotten something important that she said earlier.
"We're going to be so different, we can't live without each other."
"And so, we're going to become one... No, we're already one."
Kururi blinked in surprise and averted her gaze from her sister. Her cheeks had turned red from embarrassment. Mairu was quoting the character from the game they played, more specifically his proposing dialogue.
"What are you saying, so embarrassing..."
Mairu merely laughed hearing that. She kept on writing until she couldn't think of anything anymore. Looking to her side, Kururi's list was even longer than hers.
"... Now what?"
"We divide these. And swear we'll do things differently starting now."
"For Onii-chan."
"Yeah. For Onii-chan."
They linked their pinkies together and smiled.
And then, as they all say, the rest was history.
Yeah, I've been wanting to write this.
Just realized some error. Fixed.
