Yuki barely had time to catch his breath.
Mea straddled him playfully, her bare skin warm against his chest, still glowing with the soft aftershock of their intense, passionate exchange. Her lips were swollen from kisses, her arms draped lazily around his neck.

On his other side, Nemesis stretched languidly, brushing hair from her face. Her mischievous smirk hadn't faded even now—her body slick with sweat, legs still trembling faintly from the overwhelming ecstasy Yuki had wrung from her over the last hour.
The room was heavy with the scent of sex and satisfaction.
"Master~" Nemesis purred, eyes half-lidded. "You play far too fair with both of us. But I suppose that's what makes you dangerous."
Mea giggled, nuzzling into Yuki's shoulder. "Mmh~ But I'm not satisfied yet… Not completely."
He chuckled softly, brushing his fingers along the line of her spine, making her shiver.
But before he could answer—the door burst open.
"Y-Yuki?!"
Tia stood there, panting. Her face instantly went scarlet as her wide, green eyes took in the scene.
Nemesis raised a brow. "Oh? Did you want to join us, Tia?"
"W-What are you saying?! I-I came to talk about the next gene batch! I didn't—!" Her words twisted into a yelp as she stumbled, tripped—and fell right into Yuki's lap.

The flustered scientist found herself pinned between Mea's body and Yuki's arm, her breath catching as she felt the warmth still lingering from their earlier play. Her glasses slipped, fogging slightly. Yuki leaned in, whispered something only she could hear, and her face flushed brighter than the sun.
It didn't take long before her protests softened.
And her lips met his.

But things didn't stop there.
Soon after, Sephie and Eve entered—curious at first, and then… enticed.
Their resistance didn't last.
Sephie's veil lay discarded somewhere across the room, her eyes half-closed, her body rising and falling with slow, satisfied breaths as she lay curled beside Yuki, her voice raw from moaning his name again and again.
Eve sat quietly against the wall, skin glistening with sweat, knees drawn up to her chest, trying and failing to hide her expression of dazed contentment. She'd never expected to feel something like this—pleasure and closeness, the warmth of Yuki's touch melting all her edges.

....
Two days later…
Rin Yuki had returned to Earth with Sephie and the rest.
After introducing them to Mio and the others, he began preparing to leave this timeline.
At first, Sephie and the others didn't understand what he meant.
But after Yuki explained it himself—that he was from thirty years in the future—the truth began to sink in.
Knowing they wouldn't see him again for decades left a heavy feeling in their hearts.
Still, none of them were selfish or unreasonable. They accepted it, even if it hurt.
Once everything was ready, Yuki gave each of them a necklace set with six Infinity Stones.
A final promise, from him to them.
As he vanished, Sephie reached for him—but her hand fell through empty air.
He was gone.
....
Later that evening, as Sawa walked home with Kurumi, her fingers brushed against the pendant resting on her collarbone.
"…Hey, Kurumi… do you really think we'll see Yuki-kun again in thirty years?" Sawa asked softly, looking up at the sky.
"Of course we will."
"Because… he's Yuki."
Kurumi turned to her with a gentle, confident smile.
"…Yeah. You're right."
Sawa let out a small breath and smiled too.
Thanks to the gift of eternal youth Rin Yuki had given her, even though she wasn't a Spirit, Sawa would stay the same for the next thirty years—unchanged by time.
....
Time Skip: Twenty-Five Years Later
Inside a quiet hospital room, a silver-haired girl clung to the edge of two hospital beds, tears streaming down her face.
"Mom! Dad!!"
The doctors and nurses around her could only watch in silence, the pain in her cries cutting deep.
"…Poor girl. Both her parents… in the same accident."
"The ambulance arrived quickly, but their injuries are critical…"
"If a miracle doesn't happen soon, they won't make it."
"All the top doctors are working on it, but… there's nothing else we can do."
Amid the whispers, someone entered the room.
A tall man, incredibly handsome, with a calm, powerful presence that seemed to quiet everything around him.
"Don't worry," he said in a quiet, steady voice. "Your parents can be saved."
The girl's sobs slowed as he handed her a small slip of paper.
"Call this number. Just say one word: 'Rin Yuki.' They'll take care of the rest. And they'll save your parents."
His voice was so kind, so steady, that the girl looked up, tears still in her eyes.
His face—sharp and gentle at the same time—etched itself into her heart.
"…Rin Yuki. Is that your name, big brother?" she asked, voice small and shaky.
"It is," he said with a smile.
Then he pulled something out of his pocket.
It was a beautiful, glowing crystal. The edges shimmered like glass under a rainbow.
The girl blinked.
"What's that? Is it a jewel?"
She tilted her head in wonder.
Yuki smiled and placed the crystal in her hands.
"This isn't just a jewel. It can turn someone into a Spirit."
"A… Spirit?!" she gasped. A light of hope broke through her sadness. "Really?! Origami wants to become a Spirit too!"
So this was her—Origami Tobiichi.
Rin Yuki hadn't forgotten.
Even after all this time, he had kept his promise. He always planned to give her the Spirit Seed.
"Good. Someone will come soon and teach you how to use it," he said, rising from his seat.
"Huh? Big brother Yuki… you're leaving already?!"
Origami reached out, grabbing onto the edge of his coat.
They had just met.
But with her parents between life and death, he was the only light in her world.
Yuki smiled again and gently let go of her hand. He ruffled her soft silver hair.
"Don't worry. We'll meet again in five years."
By the time Origami could react—
He was gone.
The doctors and nurses around her kept whispering about her "tragedy," still unaware of what had just happened.
Was it a dream?
No.
The crystal in her hand—cool and alive with energy—was real.
Her fingers shaking, Origami dialed the number Yuki had given her.
A woman's voice answered on the second ring, smooth and calm.
"…Hello?"
"Ri-Rin Yuki told me to call you," Origami said nervously.
There was a sharp breath on the other end. A short pause.
"…Where are you?"
A few minutes later, a giant starship appeared over the hospital, casting a shadow across the sky.
Beams of light shot out—and three beautiful women appeared in the hallway.
Origami barely had time to explain what happened before one of them scanned her parents with a device.
Their wounds healed.
Their heartbeats steadied.
Then Origami, still holding the Spirit Seed, showed it to them.
The three women looked at each other.
"Come with us," one of them said. "You'll be taught everything you need to know."
Without hesitating, Origami nodded and followed them.
....
Before leaving, Rin Yuki visited one last room.
Inside, a teenage girl lay in bed, her heart failing from end-stage cardiomyopathy.
No one was around. No words were spoken.
He placed a hand gently over her chest.
A moment later, her diseased heart was gone—replaced with a new, healthy one.
As her consciousness slowly returned, a soft voice echoed in her mind:
"Live."
And then, silence.
