Miku and Yotsuba secretly watch as Futaro plays a stall game with a girl.

"Now he's on a date with another girl, after what he said to us yesterday," Miku mutters, her voice tinged with jealousy.

Yotsuba laughs dryly. "Uesugi-san's surprisingly popular, huh?"

The girl takes Futaro's hand, and Miku and Yotsuba go pale.

A voice from behind them startles the two.

"Mama? You okay?"

"Gaaahhh!" Miku and Yotsuba jump, turning to face their sons.

"Ren?!"

"Sora?!"

"BONK!"

"Ow, ow, ow! Mama!" Sora whines, rubbing his head.

"Ow, ow, ow! Auntie Miku!" Ren echoes, nursing his own bump.

"You almost gave us a heart attack!" Both women scold their sons in unison.

Meanwhile, Aiko and Haru sit down in the designated resting area, both letting out tired sighs.

"Man, I'm so done! Acting all day is exhausting," Aiko groans, stretching her arms.

"My hands are cramping!" Haru whines, massaging her fingers.

Rina rushes over with drinks and an ice pack for Haru. "Aiko! Haru!" she calls out.

"Huh?" Haru asks numbly.

Aiko groans, annoyed. "I'm too tired for your craziness."

"Papa's getting hit on!" Rina exclaims breathlessly.

That makes the other two perk up immediately, and they rush to Futaro together.

Aiko, taking the lead, orders, "Formation B!"

"Roger!" Haru and Rina respond in unison.

They find Futaro with the girl, and Haru grabs onto his left arm while Rina takes his right. "Papa!" they whine.

"Who is that woman?!" they ask, acting heartbroken.

"Was it all a lie when you said your time with us was the most enjoyable?" Haru adds, pouting.

"That night! That night!" Rina echoes, tears welling up dramatically.

"What? Seriously, what?" Futaro thinks, utterly perplexed.

Aiko steps up, practically sparkling with determination. "Could you not touch him so casually, please, you homewrecker?! Papa has acting practice with me now. Let's go home, Papa."

Futaro sighs and turns to the girl. "It was nice catching up. I better deal with this."

The girl nods, a bit bewildered, and bids him farewell.

Futaro turns to his three daughters, blushing from either embarrassment or anger—it's hard to tell. Steam seems to be hissing from his ears.

"Oh no—"

"Papa's pissed—"

"Run!"

"You three!! Get back here!" Futaro chases after them. "Don't just cause such a scene! What the hell were you thinking?!"

From their hiding place, Miku and Yotsuba burst into giggles.

"I guess there was no need for us to worry after all," Yotsuba says, wiping tears of laughter from her eyes.

"Yeah, our girls are the best," Miku agrees, smiling proudly.

Complaints come from their two sons, but Miku and Yotsuba ignore them, getting back to their tasks with light hearts.

As the sun sets on the final day of the festival, the air is filled with a mix of joy and melancholy. The quintuplets and Futaro gather with their future children, cherishing their remaining moments together. The school grounds are quieter now, the festival winding down, and a gentle breeze rustles the decorations.

Only these eleven individuals are left.

Suddenly, a shimmering light appears in the center of the courtyard. Everyone turns to see a portal forming, its edges glowing with a soft, ethereal light. From it, older versions of the quintuplets and Futaro step out, looking both familiar and different. They carry an aura of wisdom and experience, their eyes filled with love and gratitude.

"Mama!" Aiko cries, running to her mother, tears streaming down her face.

The future parents embrace their children, tears in their eyes. "It's time to go home," future Miku says gently, her voice soothing and calm.

Future Nino turns to her younger self, her expression serious yet tender. "Take care of them, and believe in your strength. You’re stronger than you think," she says, placing a hand on her younger self’s shoulder.

"You've got this, sis," future Ichika adds, giving a reassuring smile to her younger version.

The children cling to their parents, not wanting to let go. "We’ll miss you so much," Haru whispers, her voice choked with emotion.

Future Futaro steps forward, looking at his younger self with a knowing smile. "You’ve done well. Keep doing what you’re doing, and everything will turn out fine," he says, his words filled with a sense of destiny and reassurance.

As the portal begins to close, the children wave goodbye. "We'll always remember you!" Rina calls out, her voice breaking.

The younger quintuplets and Futaro watch with a mixture of sadness and hope as the portal slowly starts to fade. The future parents hold their children close, sharing one last moment of love and warmth.

"Take care, and we’ll see you again," future Yotsuba says, her eyes sparkling with unshed tears.

"Remember, we’re always with you, in your hearts," future Itsuki adds, her voice gentle and comforting.

With one final wave, the portal closes, and the future parents and their children are gone. The courtyard is silent, the only sound the gentle rustling of the leaves in the breeze.

Futaro and the quintuplets stand there, feeling a profound connection to their future. They know they have been given a precious gift—a glimpse of the love and strength that will carry them forward.

"We’ll make them proud," Ichika says softly, breaking the silence.

Nino nods, wiping away her tears. "Yeah, we will. Together." Then a grin forms on her face. "We'll do everything in our power to ensure our kids' existence." She turns to Futaro with a knowing glint in her eyes. Her sisters catch on and do the same.

Futaro blushes bright red.

The quintuplets and Futaro embrace, their bond stronger than ever. They know the future holds many challenges, but they also know they have the love and support of their family to guide them through.

As they walk away from the courtyard, the sun sets on the school festival, marking the end of one chapter and the beginning of another. The memories of their future children will stay with them, a reminder of the love and strength that bind them together.

And in their hearts, they know that no matter what the future holds, they will face it together, as a family.
