The plane engines slowly died down, the air of Japan entering the lungs of a certain sister that spent a lot of her time overseas for the past five years. She put on a pair of shades as well as a large sunhat to hide her face. "I'm finally back. This country is the same as always."

"You said it..." Another voice caught her attention, the origin of which approached behind her. "Onee-chan, how was first class?" Hair flowing down to her back, tied into a ponytail with six segments; hexagonal earrings and a bracelet with a similar design, black, and gold-colored accents. Wearing a slim, thin, black coat over her white blouse that was buttoned up to the collar. A mini skirt with a simple striped pattern covered the top of her black thigh highs. Simple black heels clicking against the tile floor of the airport. A pair of black-rimmed glasses covered her eyes as she smiled towards the eldest Nakano.

"Onee-san, huh? It's been a while since I've been called that." Ichika chuckled, turning around to walk beside the youngest of her siblings.

"It's been a while since I've had to say it. After all, we've nearly dropped all our honorifics in the states. And we also don't get together often" Mutsumi double-checked the contents of her bags, at least the ones she could check easily while on the move. She checked her phone quickly before pocketing it, smiling at whatever she saw.

"Aw, does Mutsumi-chan miss onee-san's teasing?" Ichika leaned forward, gently patting Mutsumi on her head.

"Let's go..." Mutsumi brushed her hand away, walking ahead of the actress. "They're waiting for us." She pulled out an invitation from the pocket of her coat. "Itsuki's waiting outside." She dragged her own luggage out, walking onto the street to find a small minivan waiting for them.

"Hi! Did you lose weight?" Mutsumi joked as she met up with the fifth sister. "I kid, I kid."

"Honestly, would it kill you to stop bringing that up?" Itsuki sighed, unable to get flustered by her body as easily. The three of them entered the vehicle after they packed their bags. "Wait...how did you know I was here? I wanted to surprise you." The fifth sister wondered as she drove the three of them through the city. Mutsumi pulled out her phone, opening up an old app she made a few years ago.

"They look good on you. I worked hard to make them" Mutsumi joked, noticing the blip of red that moved on the map of her screen. She leaned over and picked one of Itsuki's stars out of her head, pulling out a small compartment that blended in that it was unnoticeable to everyone except the one that made it.

"Oh, we're heading to where Nino and Miku are," Ichika said, leaning over to glance at the screen as a purple and blue dots appeared on the edge. The map was zoomed out, meaning that they were quite a ways away from the second and third sisters; it took an hour and a half for them to arrive due to the traffic that slowed cars down to a crawl.

"Hmm... this place is..." Mutsumi muttered, looking away from her screen as they drove on familiar streets, up to a familiar house in the more rundown part of the city. A large sign spelled out their name in lights, though it didn't always say that.

"Woah! Look at this!" Ichika blurted out, instantly captivated by the interior of a tiny cafe that felt very homey. A small bell signaled their arrival as they swung open the door. Inside, waiting for both of them

"Long time no see, you two." Miku smiled, pouring a pair of drinks out for her sisters. The interior was furnished with the basics of a restaurant bar. Containers with labels that were written in either her or Nino's handwriting, bottles of alcohol, pots, and pans that were put out for decoration.

"It's nice to see you two doing well..." Mutsumi looked around, pacing around absentmindedly as she took in the atmosphere. "I can't believe that this was the old Uesugi cafe..."

"It's very...lively." Ichika teased, waving her arms around to gesture towards the empty chairs. The two restaurant owners looked back at her with irate expressions, narrowing their eyes as they made a quick meal for their guests.

"Oh, it looks like someone got more sarcastic with their time overseas." Nino narrowed her eyes in annoyance as Mutsumi went behind the counter. The second sister tilted her head, watching curiously as her younger sibling returned to the car to get something from one of her multiple bags. "What are you...Mutsumi!?" She shrieked as the sixth sister returned with a small drill and toolbox in her hands.

"Ah, sorry...it just seemed like this would help." Mutsumi pulled out a few small sensors. "It would keep track of the amount of foot traffic you guys get."

"I see..." Miku looked around, scanning the sensors before shaking her head. "Thanks, but I think we'll refuse for now." She walked around the counter, holding multiple plates of food.

"What?" Mutsumi asked as she set her things on a table. Miku set a plate of food down for everyone, and some extra made especially for the sister with a large cowlick.

"I want to rely on our strength," Nino said, smirking wide as a disappointed Mutsumi returned the things to the car. "After all, we've been getting popular recently. We might even overtake Ichika soon."

"Overtake me?" Ichika sat down, glancing at the food placed before her. "Have you been spying on me?" She teased once more, leading to the second sister's eyes widening in embarrassment as Nino whined.

"I don't!" She cried out, though her face didn't exactly reinforce her words. Nino had turned as red as her hair, which was now tied into two pigtails. She huffed, vulnerable to Ichika's shenanigans due to her lack of exposure deteriorating the resistance she had back when they were living together.

"She does..." Miku said bluntly as Mutsumi sipped the drink the third sister provided. "How do you like it?"

"It tastes familiar." The sixth sister smacked her lips, trying to isolate the notes that danced on her tongue.

"It should, it's your recipe." Nino crossed her arms, pulling out a jug from a refrigerator hidden behind the counter. A very inviting sight to the sixth sister, perhaps five mugs worth of her cold brew coffee that fueled her for much of her life.

"Aw, I missed these." Ichika smiled as the sound of Itsuki clearing her throat drew all their attention towards her. "Us just hanging out together."

"That would be your fault, no? You need to visit more often, you and Mutsumi both." The fifth sister spoke succinctly, leaving no room for objection as she pushed up her glasses.

"Hai, hai. Sensei~ I'm sorry that I don't have many days off." Mutsumi joked in her most American-sounding accent. "Oh, by the way. Ichika's recent movie..."

"Heh, still the first one to die." Nino chuckled, taking a seat with her own plate of snacks that she intended to share. "Some things never change. If you get sick of the spotlights, you can always work here." Pouting as she jerked her head away from the crowd, unintentionally making her hair smack into Mutsumi's face as she opened her mouth to steal some food away from Itsuki's plate.

"Just say that you miss her." Mutsumi sneered, sneaking a couple of cookies away to munch on while she drank the coffee. She blew away the wayward strands of her sister's hair. The youngest's annoyed tone brought some more levity to the room, much of which was at her expense as her elder sisters teased and taunted her.

"Sorry, I'm late!" A voice interrupted the chorus of laughter that came from each of the girls, indicating the arrival of the missing sister.

"What the fuck happened to you!?" Mutsumi yelled, glancing at Yotsuba's soaked clothes and sweat-covered face.

"Hehehe! I was so excited...I couldn't sit still so I rode my bike all the way here instead of taking the train." The fourth sister, ever the athlete, puffed up her chest with a bit of pride. She panted as she walked over to the group, collapsing into a chair as Miku got her some water.

"I'm disappointed. Our apartment isn't even that far by bike. I thought you'd be able to get here faster." Mutsumi sighed, crossing her arms as she gazed at Yotsuba. It was true that the luxury highrise they resided in during their teen years wasn't that far if Fuutarou could walk to it in a timely manner every time they studied together.

"Oh, nobody told you," Miku muttered, smiling at both ends of the sextuplet spectrum.

"Yotsuba recently moved in with Uesugi-kun." Itsuki chimed in, setting down her sandwich and wiping away the crumbs that stuck to her lips. Ichika and Mutsumi both turned to lean in closer to Yotsuba, who, at this point, shrank down under the pressure of their stares.

"Ara~ Is that right? How is it? You seem happy?" Surprisingly, Ichika's question was the more innocent one.

"Yeah, how is it? How is he?" Mutsumi teased, nudging her sister with an elbow. Yotsuba turned red, hiding her face in her hands.

"There are some things that are hard to get used to. But it's nice. And Fuutarou..."

The five other redheads began smiling as Nino cleared her throat. "Well, let's not get distracted. We called you out here for a reason." The most straightforward sister declared as Mutsumi and Ichika maneuvered around the bride-to-be. "Here's a memento from mom: her earrings."

"But that also means..." Mutsumi smirked as her hands gripped around Yotsuba's arms to fasten her in place. "Don't struggle."

"I won't. I'm ready!" The fourth sister said stoically, letting Ichika hold her head steady.

"Everyone, on three. One...two..." Nino said as Ichika handed her a device to give Yotsuba a piercing.

"Yotsuba! Congratulations on getting married!"

"Ow!"

The process repeated itself for Yotsuba's other ear, though the pain quickly subsided. The fourth sister's ribbon flopped down as she took a few steps towards the extra plates of food. She drowned the residual sensation with the joy of stuffing her mouth, washing it all down with a sip of water.

"I-It feels like not all of those feelings were congratulatory!" She looked at Nino, who was holding the piercer, who shook her head in denial. The fourth sister looked at the earrings, holding them carefully as the six of them headed for the venue.

"My makeup artist said she'll be coming a bit late," Ichika said, looking at her phone as she received a text from Mutsumi.

"And my...our old photographer friend would be documenting everything. It's going to be fun messing with him again." The sixth sister pocketed her phone after sending a text to a certain group of people. "You guys remember Tsubaki-san, right?" She asked though the others weren't really paying attention to what she was saying.

"Are we really going through with this?" Yotsuba spoke hesitantly, now having second thoughts on what was to come.

"It was your idea though. Don't give up now that we're so close."

"We have to evaluate Uesugi-kun, after all." With that, the six of them entered the car after they closed down the cafe for the day.

"Thank you for your patience. Please rest for a moment. There are a few minutes before the start of the reception, so please relax. We will be sure to call you once the bride is finished changing." The ceremony had concluded just a few minutes prior, and the man of the hour was currently slouched in a chair secluded from any of the guests. He tugged at his collar, releasing heat as well as the pressure that built up due to his stress.

"Umm, excuse me. Have you seen the bride's sisters by any chance?" Fuutarou asked one of the organizers that checked on him.

"Yes. They were the first to arrive today."

"Is that right?" He felt a bead of sweat trickle down his neck. He sighed, already mentally preparing to deal with the Nakano siblings' antics. Fuutarou already grew concerned when he didn't see them during the ceremony, and his concerns were now justified.

"Excuse me, Mr. groom. A relative of the bride has arrived."

"Oh great! I wasn't sure if he'd arrive. I'm curious as to why you didn't attend the ceremony." He smiled as the black-haired doctor entered his room and scanned the area.

"My apologies, I had only made up my mind recently." Marou walked around slowly, glancing into the mirror as he adjusted his tie.

"Hello, dad."

"Please refrain from calling me that." Maruo requested and Fuutarou had no reason to refuse.

"Thank you for coming. I was worried that you wouldn't come to see me." Fuutarou bowed to his father-in-law. "I apologize for all the disrespectful things I did in my youth."

"Uesugi-kun. There's something I'd like to ask you. Would you say that Yotsuba is happy? Truly happy without a shadow of a doubt." He looked through the former tutor with his soul-piercing stare.

"Yes. And I feel the same way." Fuutarou replied quickly as Maruo glanced at a bottle of wine that was given to him. "Would you like some?"

"Yes, thank you." The doctor sat down, holding a glass in one hand to allow Fuutarou to pour enough for him to enjoy.

"My mother passed away over ten years ago..." Fuutarou muttered as he set the bottle down. "She passed in an accident right after we took out a loan to achieve her dream: our old restaurant. That was the cause of our debt." He took in another deep breath. "It might be half of the reason why my pops gave the space to Nino and Miku. Not only does she want to help them, but, in a sense, he wanted to see mom's dream come true; entrusting her dream to those two was probably why." He shut his eyes as he thought about his next words carefully. "Someone who's committed to loving one woman for the rest of his life. I'd like to be a man like that; like the two fathers I know."

"I told you to refrain from calling me that," Maruo said coldly, sipping the wine as he turned his head. "I'm not used to being called father."

"Mr. Groom, the bride is requesting your presence." Fuutarou gave a short bow before he left the room.

"Maruo, your tsundere is showing again." The second father entered the room, teasing the doctor as he grabbed the other wine glass. "Ah, we've gotten old."

"Don't lump me in with you. I look far younger than my actual age."

"My skin's still supple and smooth." Isanari took a seat, taking the bottle with his other hand. "I thought you only drink when there's a special occasion?"

"And this is one of them." Maruo forced himself to drink, hiding the smile that he had by fixing his lips to the glass.

"You think things will go well for them?"

"That isn't something a parent can tell. However, I'm sure that it will not go smoothly. He is marrying my daughter, after all." Maruo said, chuckling to himself silently.

"Yotsuba, I'm here."

"Alright! Sorry for making you wait. I'm almost done getting dressed, so please be patient."

"It seems like everyone's here," Fuutarou said, looking at the wide curtain that covered half of the room. "I don't know what you're planning, but you six never change. Even now, you cause me trouble."

"Does that include me too?"

"You were the most troublesome."

"Quit flirting, it's so gross."

"You know, now that I think about it, you never really did this kind of thing while we were in high school, right Mutsumi?"

"You're right...I guess the situation never arose."

"My, my. Mutsumi-chan is finally joining in on the family tradition."

"It's not a tradition if we don't do it on a consistent basis."

"Good grief..." Fuutarou said as one of the Nakano sisters pulled the curtain to the side, revealing six women all wearing the same dress, with the same hair, with the same face. "What a nightmare."

"Well, it's time for your first sextuplet game with all six of us. And probably the last one too."

"As long as there's love, you'll be able to tell us apart, right?"
