...
Reiji laughed heartily along with Reina, although Reina's laughter were more lighter compared to Reiji's middle-aged man laughter.
"I see!! I'm surprised that you never told me that you have a sister! No wonder she's infamous in school as well!"
Rirota squinted at Reiji's words, "Oh? So you were snooping around in school looking for babes, huh?"
Reiji waved his hand, shaking his head at the same time, "No, no!"
Reina wiped down her laughing tear to look at her friend, Riro, "Riro-chan, you could've told me that you had a twin brother. I didn't expect him to look so closely as you though."
The two Rirota sighed heavily.
Reiji stopped his laughter before speaking to Rirota's 'twin sister', "Where's my manners? I'm Reiji Kirigaya, Reina's older brother."
Rirota narrowed his eyes at him, "Don't you have an older brother, Kaeden-san?"
Reiji nodded, "Yep, so do Reina!"
Rirota had his fingers against his chin, "Hm."
Riro blushed slightly staring at Rirota's serious expression. She wasn't sure why she's feeling like this but ignored her own thoughts to introduce herself to Reiji.
"We, I mean, the both of us have the same name, Rirota Xalysia. It's nice to finally... see another annoying person aside from your sister, Reiji-san."
Reina laughed inwardly as Reiji had a shocked expression, "You're just like Rirota, Rirota-chan!"
"Ew, don't call me Rirota-chan.", Riro felt gross hearing him call her that. Reina noticed the blood still leaking out of her brother's nose, "Reiji, wipe your nose. Also, only I can call Riro, Riro-chan."
Riro sighed at these two antics, her mind also pondered about these two's relationship, [They say that they're siblings... but, Reina, you never told me that you have two brothers. Something feels odd and I really don't like it.]
She tugged on Rirota's sleeves, making him stop thinking deeply, "Rirota, that nosy girl's name is Reina Kirigaya."
Reina blushed in embarrassment, "Nosy?!"
Rirora sighed heavily as he intro himself, "You've heard from Riro, right? I'm Rirota Xalysia, just call me Rirota. I'm sorry to hear that you're living with such an annoying brother of yours, Reina-san."
Reina waved her hands shyly, "It's okay! I'm pretty much act the same like my brother, although he's more like a brute than a lady like me---"
Riro casted a doubt check on Reina, "I doubt it, you're just as a brute like your... monkey brother."
Reiji made a sad face, he was hurt from the twin Rirota to call him by the same nickname he didn't like, "I'm... not a monkey..."
The two Rirota sighed.
Reina patted her monkey brother gently, "There, there. At least Riro-chan didn't call you silly goose. She kept calling me that."
"Now that... nevermind."
Reina tilted her head, confused for a moment before going back to tending to her brother's bleeding nose.
Rirota almost outright call Reina a silly goose after noticing an odd resemblance between Reina and a dummy goose. He closed his lips tight as he didn't want to hurt their feelings.
[If I said it, it's going to be deja vu.]
Riro noticed his actions and sighed inwardly, [At least he didn't say it. I almost felt a deja vu moment there.]
...
The Kirigaya stayed over until having lunch at Rirota's house.
After sending them off to their way to home. Riro closed the door tight and faced Rirota with a serious glare.
Rirota sighed inwardly at the sight of her beautiful face with an interesting glare at him.
"So, you thinking what I'm thinking?"
Riro gave him a smirk which he finds attractive. She know how to get young men fall in love for her, he inwardly shook his head to rid himself of those thoughts to answer her question.
"No need to ask me for confirmation, but yes. I think that we might be in a completely different world which merged our own parallel worlds into one."
She nodded, agreeing fully on his assessment, "I had my doubts the moment Reiji-san said that he was her brother. As far as I know from Reina, she never spoke about her monkey brother. She only talked about her famous celebrity brother named Kaeden or-"
He finished her words brilliantly, "Kero KC, his stage name."
"But yeah, I had my doubts as well. I've been to that idiot's place a couple of times and never have I met this Reina."
She had her finger against her chin, "How about tomorrow's school then? Will we meet more of our friends genderbent as they acted as siblings?"
Rirota had a dark expression on his face, he had forgotten about school and the rest of the world. A sigh escaped him as he nodded lightly, "Hopefully we can return back to our own worlds... say, Riro."
A question popped in his mind, he felt it was important enough for him to ask her, "Your mother... is she alive or dead?"
"Are yours?", she asked a question instead. He sighed sadly, "My mother died in an accident during Winter, yours?"
"Alive, well... I'm sorry to hear that, Rirota.", she felt bad for him. This was something different in their similar lives till now, Riro's father died to lung cancer while she learned of Rirota's mother dying in an accident involving a car in the slippery snowy road.
However, those little differences meant something similar to both of them as they grow up, both Rirota were delinquents due to their rough attitude and other related reasons behind it.
Little did they two know that tomorrow, most students would call them the power couple.
