Uncle from Another World: Our Secret Nights – An Adult IF Route
One day, Takafumi finds an old videotape in his uncle Yusuke's room while he's unconscious. Playing it back, he discovers it contains explicit records of his uncle's 'secret relationships' with three heroines from the other world of Gran Bahamul—relationships no one else knows about.
The first to appear is the tsundere elf. Initially cold, she is drawn to his love for the Sega Saturn. On a stormy night, alone with him at an inn, she clings to him with a sweet voice, saying, 'Just for tonight, l
Uncle from Another World: Our Secret Nights – An Adult IF Route - The Cave Confession – The Night Siena Undressed, and Takafumi’s Heart Completely Broke
The static on the TV stung his eyes.
Noel's face, which had been on the screen just moments ago, was still burned into his mind. The expressionless doll-like face that had crumpled into tears. The face that had clung to his uncle's chest, sobbing. And then — the face that had forgotten everything.
The air in the room hung heavy and still.
Takafumi stared at his palms. His fingers were still trembling. The jealousy that had flared up watching Elysia's footage, after hearing Noel's story, had now cooled and hardened like lead.
"That's quite the wrecked expression you've got there."
On the bed, Yusuke was smirking.
"Shut up."
His voice had no strength.
"Hey, it's not over yet."
Yusuke leaned forward and pulled one tape from the pile. The label read, in ink: *Cave Arc — Siena*. He casually dropped the tape onto Takafumi's lap.
"...There's more?"
"This is the last one. It says Cave Arc, doesn't it?"
Takafumi stared hard at the tape.
(*I can't take any more.*)
A voice spoke somewhere in his head. If he watched any more, he wouldn't be able to recover. But — his hand moved on its own, grabbing the tape. He shoved it into the deck. As he pressed play, a dry, self-mocking remark slipped out.
(*Seriously, I never learn.*)
The static cleared.
A dim, sprawling cave filled the screen.
Rock walls flickered orange in the torchlight. Stalactites hung from the ceiling like fangs, and water droplets made faint, echoing sounds. In the footage, Yusuke was crawling through a narrow passage.
"Oji-sama!"
A sudden voice.
From the edge of the screen, a small shadow leaped into view.
A girl with waist-length blonde hair tied in a ponytail. She was about a hundred and forty centimeters tall — clearly smaller than an adult. But the leather armor she wore was covered in scars, and a short sword hung at her hip. Her eyes — were as sharp as a bird of prey's.
She threw herself at the Yusuke in the footage.
"Oji-sama, this place is dangerous! I told you not to go off on your own!"
She was angry, yet her voice was bouncing with energy.
"...Oji-sama?"
Takafumi muttered, genuinely taken aback.
"She called me that from the very beginning,"
Yusuke said with a nostalgic smile.
"She decided it herself. Said since I was used to being called 'Oji-san,' she'd call me 'Oji-sama' out of respect."
A fresh wave of something hit Takafumi's chest.
*Oji-sama* — she called him *that*. And from a petite fifteen-year-old warrior, no less. Elysia had told him "for a mere human." Noel had forgotten him with a "who are you?" And now this.
(*One after another...*)
The irrational jealousy kept piling up, bit by bit.
The footage continued.
Siena pulled Yusuke by the hand, guiding him deeper and deeper into the cave. She had apparently been attempting her coming-of-age ritual — a solo monster hunt. Yusuke had wandered in by chance.
"This is the second stratum. Look, the patterns on the stalactites are beautiful, aren't they?"
She pointed at the wall.
At that moment —
*RUMBLE.*
The screen shook violently. A roar. Rocks fell from the ceiling. The torch went out, plunging everything into pitch blackness for an instant.
The dust was intense. The footage distorted, and only Siena's faint coughing could be heard.
Eventually, the dim torchlight flickered back on.
The entrance was completely buried in rubble.
"We're trapped,"
Siena's voice was surprisingly calm. She first turned back toward Yusuke.
"Oji-sama, are you unharmed? Are you injured anywhere?"
"Worry about yourself before me."
The Yusuke in the footage said.
Siena let out a soft laugh.
"As long as you're here, Oji-sama, I'll be fine."
On the sofa, Takafumi froze with his arms still crossed.
(*—She can just say that?*)
Those words just now. There wasn't a shred of hesitation. It was a voice that truly meant it from the bottom of her heart. He envied someone who could say something like that without wavering. He envied his uncle, who got to hear it. Both were so far removed from himself. That pain spread slowly through the center of his chest.
Time passed in the footage.
The two sat down near the rubble, waiting for rescue. Siena sat hugging her knees. Her small frame looked even smaller.
After a while —
She slowly stood up.
"...Siena?"
Yusuke's voice.
Siena didn't answer. Instead, she reached for the clasps of her armor. The faint sound of metal fasteners coming undone. Her breastplate came off, her shoulder guards falling to the floor.
"What are you doing?"
Siena silently unfastened the last of her leather armor.
What emerged from beneath the armor were shoulders thinner than expected, and the delicate lines of her collarbone. Her blonde hair clung to her forehead with sweat. She lifted her face. In the torchlight, he could see a film of tears over her eyes.
But — her voice did not waver.
"If this might be the end,"
She took a step closer to Yusuke.
"I don't want to have any regrets."
She knelt. Right in front of Yusuke, she reached out and touched his cheek. Her fingers were trembling.
"I've always loved you, Oji-sama."
Her voice went slightly hoarse.
"So —"
She wrapped her arms around Yusuke's neck herself.
"You can do whatever you want with me, okay?"
With those words, she pressed her lips against Yusuke's.
Takafumi had risen from the sofa.
In front of the TV, his feet wouldn't move. His face burned hot. His fingertips were cold. Deep in his ears, his heart pounded noisily.
In the footage, Siena clung to Yusuke's neck, kissing him desperately. Their tongues intertwined, and small sounds escaped between breaths. A fifteen-year-old girl — deciding everything herself, offering herself without hesitation. That purity shook Takafumi's chest painfully.
Elysia's possessiveness.
Noel's emotional explosion.
Siena's devotion tonight.
In Takafumi's mind, having watched all three tapes, the fact that all of these were directed at a single person — his uncle — pressed down on him anew with immense weight.
(*All three of them... every single one, only for Oji-san.*)
The footage was approaching its climax — just then.
*Click.*
Yusuke had manually stopped it.
"Wha —"
Takafumi spun around.
His uncle was leaning against the bed, grinning.
"I figured from here on, it'd be better if I explained it myself."
"Hah!?"
After showing him *that* much — he was stopping *now*?
But ignoring Takafumi's protest, Yusuke began to speak.
"Siena's hands at that moment, they were so surprisingly small it shocked me. Her body under the armor was thinner than I'd thought, and when I held her, she fit completely in my arms. Her body temperature was strangely high, and when I said she was hot —"
"...Stop."
Takafumi forced the word out.
But Yusuke didn't stop.
"—'It's your fault, Oji-sama,' she said. Apparently she could tell my heart was pounding like crazy, and Siena was laughing. Even in that situation, she looked so happy."
"I said stop!"
Takafumi's voice echoed through the room.
Yusuke fell silent.
"...That's enough."
Takafumi dropped onto the sofa with a thud. He covered his face. Elbows on his thighs, he stared at the pile of tapes on the floor through the gaps between his fingers.
Words wouldn't come.
It wasn't just jealousy or envy anymore — those mild emotions were gone. Something darker, colder, a more fundamental sense of defeat was spreading slowly through his entire body.
Elysia had directed a possessiveness at him that transcended the lifelong marriage vow. Noel had opened the door to her emotions for him. Siena had entrusted him with everything. Such experiences had happened to one person *three times*.
(*Oji-san is too special.*)
Takafumi stared at the pile of tapes on the floor, motionless.
Nearly a hundred VHS tapes. There were still so many labels he hadn't seen. On all of these, someone only his uncle knew, emotions directed only at his uncle, were recorded.
After a while —
"Only Oji-san is special."
Though it was his own voice, it sounded distant.
"I can't do it. That kind of world. That kind of life."
His voice trembled. The back of his eyes felt hot. No tears came, but something heavier clogged his chest.
Three women, all of them, had given everything to his uncle alone. He could never become that kind of person. Someone like him, who had never once been able to say "I love you," didn't even have the qualifications to begin with. He'd always blurred jealousy and admiration together — but he couldn't fool himself anymore.
(*There's absolutely no way I can.*)
A black self-loathing began to overwrite all the admiration he'd held until now.
Silence fell over the room.
Outside the window, the darkness of night spread across the apartment parking lot. A single streetlight flickered faintly orange.
"I see."
Yusuke said quietly. It wasn't anger or consolation — just a single word, like a confirmation.
Then —
His uncle's gaze shifted toward Takafumi's right hand.
In Takafumi's hand was the Sega Saturn keyholder he'd been gripping without realizing when he'd picked it up. A small, old plastic console, dirty with dust. He didn't even know when he'd grabbed it.
His uncle said nothing.
But — that gaze, for just a moment, brought back the scene in the footage where Siena had clutched the same-shaped keyholder like a treasure.
Takafumi noticed his uncle's gaze and looked up.
"...What?"
His voice was hoarse.
Yusuke didn't answer. He just raised the corner of his mouth slightly and shifted his gaze out the window. What he was looking at in the darkness visible through the gap in the curtains — Takafumi couldn't tell.
But.
(*Maybe.*)
At the bottom of his chest, filled to the brim with despair, a pinpoint of light pierced through. What it was — no one had put into words yet.
The deck ejected the fifth tape.
Only the small *whir* of the mechanism echoed through the quiet room.
