[Chat Group]
Miyuki Uchiha: "Hmm? What are you two up to, Your Highness Daemon and Senpai!?"
Yamamoto Mei: "…Don't tell me… it's exactly what I think it is."
Miyuki Uchiha: "Could it be... Senpai is about to overtake the rest of us and claim Daemon's virginity first!?"
Erina Nakiri: "Pfft—there's even a ranking system for this kind of thing? Is it a race now?"
Esdeath: "Of course it is. Love is a battlefield. If you hesitate, you lose."
Jibril: "Indeed. I usually have no interest in romantic matters, but if I were to fall for Daemon… I would never let someone else be the first to take him."
Miyuki Uchiha: "Oh? Then Jibril, what would you do if someone else did get to him first?"
Jibril: "I'd sever her head and place it at the head of our bed—so she can watch us for eternity."
Miyuki Uchiha: "...Uhh."
Sakura Tosaka: "T-Terrifying…"
Erina Nakiri: "Wait… could Jibril actually be one of those obsessive 'yandere' types?"
Jibril: "Love makes us all a little irrational. I'm just more honest about it."
Miyuki Uchiha: "...Anyway! Wait! We're getting off track! Isn't the real issue here that Senior Sister is still in her dragon form!? Shouldn't she, uh, at least shift back into a human before going to bed?"
Yamamoto Mei: "A dragon and a human...? Is that even physically possible?"
Miyuki Uchiha: "Hey! Why did the livestream shut off?! Don't end it there! We're all girls here—what's the harm in sharing? Show us!"
But just as Miyuki's voice grew louder, the group chat went dark.
Daemon had closed the feed.
Naturally, there was no way he was going to let the chat group—regardless of gender—watch what was happening in his bedroom.
More importantly, Kasumigaoka Utaha was far too embarrassed to allow that.
Daemon himself didn't mind being seen. But this wasn't just about him.
And so—regrettably for the group—the mythical scene of a man and a dragon joining as one would remain unseen.
Even in the age of gods and beasts, such a union would've been rare. A true moment lost to history.
Several hours later…
More than half a day had passed since the mission's deadline began ticking down.
If Daemon hadn't completely wiped out both the Zouken Matou family and that festering pile of filth called Dirty old man with a single strike, they might've actually failed due to timeout.
How indulgent.
The goal of traveling to other worlds was to grow stronger, not to drown in the warm embrace of temptation.
But truth be told, there wasn't much left to do right now. The Fourth War hadn't officially begun. No Heroic Spirits had been summoned yet.
Even that old worm Zouken hadn't released a single Noble Phantasm. Utterly pathetic.
Should he now go hunting vampire ancestors across the planet just to keep busy?
Sneering internally at the weaklings of this world, Daemon emerged from the bedroom, fully refreshed.
Just as he was stepping into the hallway, he ran into Aoi Tosaka coming up the stairs.
She wore a soft green dress and black stockings. Her long, dark hair shimmered faintly in the light—she was the picture of a gentle, elegant wife.
"Good afternoon, ma'am," Daemon greeted with his usual charming smile.
"Ah… G-Good afternoon, Mr. Daemon…" Aoi replied, eyes darting away shyly.
Her gaze flicked behind him—toward the closed bedroom door—and Daemon instantly understood.
Ah, she must've been startled by the sight of Kasumigaoka in her full dragon form…
He sighed inwardly and cursed Utaha's shameless boldness.
Still wearing a pleasant expression, he asked, "Was there something you needed, ma'am?"
"Yes… actually," Aoi hesitated, clasping her hands. "My husband… he wanted to speak with you about something rather important."
"Tokitomi Tosaka? Understood."
Daemon's curiosity was piqued.
Could it be that this man has already realized he'll lose the Holy Grail War and now wants to entrust me with his wife, daughter, and fortune ahead of time?
Amused by the thought, Daemon started heading downstairs—but paused.
"Oh, one more thing, ma'am."
"Y-Yes?"
Aoi flinched slightly at being addressed again, but stood attentively.
"Please take care of my girlfriend while I'm out. I'd appreciate it."
Aoi blinked in surprise, then visibly relaxed.
"O-Of course, Mr. Daemon! I'll take good care of Miss Kasumigaoka."
But even as she smiled and reassured him, a strange mix of disappointment and relief stirred in her chest.
Daemon was the kind of man who commanded dragons and summoned thunder.
In myth, such heroes often took wives, not asked for help with them.
Her cheeks flushed at the memory of something her husband had whispered to her the night before…
"If you truly wish to protect our daughters' future, then earn Daemon's favor. Even if it means…"
No, no. I'm overthinking it. This is all Tokitomi's fault for planting strange ideas in my head…
Aoi pushed open the bedroom door.
The moment she stepped inside, her expression froze.
"Ah—!"
A gasp slipped out before she clamped her hand over her mouth.
Before her lay the resting form of a massive pink dragon—Kasumigaoka Utaha, in her natural state, curled up in the sheets, utterly spent.
Aoi stood frozen. W-What in the world…!?
She had suspected Miss Kasumigaoka was a dragon, but she never imagined… they would remain like that after such an intimate battle.
Wait, was this always the way legendary heroes subdued monsters and divine beasts!?
Blushing furiously, Aoi stepped forward and began tending to the disheveled dragon-girl. As she wiped the scales clean with a warm towel, her fingers brushed a slick white stain across the dragon's body.
"…Seriously, Mr. Daemon. You're far too reckless… how does someone get milk on Miss Kasumigaoka like this?"
But even as she muttered the complaint, Aoi's hand stopped.
Wait. We didn't bring any milk for Daemon. Then… where did this come from?
Meanwhile, Daemon paced leisurely toward the Tosaka family's magic workshop.
"Come in, Mr. Daemon," a calm voice called out.
He pushed open the door with a faint creak—and paused.
Inside, Tosaka Tokitomi sat at the guest side of the room alongside his two daughters. The main seat had been left empty—clearly for Daemon.
"Brother Daemon!" Sakura's eyes lit up when she saw him.
But her joy lasted only a second before fading. Her smile dulled, and a shadow clouded her expression.
She wasn't a child anymore. Not completely. She understood what the group chat had hinted at.
And the fact that Daemon and Utaha had stayed locked in that room for over ten hours…
Her heart ached. Worse still, this was her home. Her parents had prepared that bedroom for them.
When she looked at her father—her biological father—resentment stirred in her chest.
Why did you allow this…?
As for Rin Tohsaka—
The little girl puffed her cheeks, glaring for a moment before skipping over with a mischievous grin.
"Good morning, Mr. Daemon—lover of high school girls!"
"Huh?"
Daemon blinked, taken off guard. Rin's strange greeting caught him mid-thought. A beat later, realization dawned.
"…You were eavesdropping on my conversation?"
His gaze shifted toward the young, pint-sized version of the famously tsundere Rin Tohsaka. Her sharp little eyes avoided his, and he raised an eyebrow in amusement.
"What do you mean eavesdropping?! This is my house! I was just... passing by! At night!"
Flustered and red-faced, seven-year-old Rin stomped her foot. Whether it was from embarrassment or anger, even she couldn't tell.
"S-Sister… Brother Daemon was just joking,"
Sakura murmured, tugging gently at Rin's sleeve and glancing up at Daemon timidly.
"Ahem…"
Tokiomi Tohsaka's deliberate cough broke through the awkward air, drawing all three pairs of eyes to the gentleman seated at the head of the room.
"It's good to see that Mr. Daemon gets along so naturally with my daughters. That alone puts my heart at ease."
He smiled faintly, warm but tired, and pulled a folder from beneath the table.
"This is a contract. Technically a scroll, but with no magical binding or legal power. In truth, it's just paper."
Daemon took it hesitantly, and as his eyes scanned the document, his expression slowly shifted from confusion to stunned disbelief.
It was simple and direct:
[Should Party A (Tohsaka Tokiomi) perish, become incapacitated, or otherwise unable to care for his family during the Fourth Holy Grail War, all his patents, properties, land, and wealth will transfer to Party B (Daemon).
Party B, in return, must take in and care for Party A's daughters, Rin Tohsaka and Sakura Tohsaka, as well as his wife, Aoi Tohsaka.]
Daemon's grip tightened slightly on the scroll. No magic. No coercion. No leverage.
It was trust.
Is this guy trying to push his entire family onto me…?
Even for someone like Daemon, who'd seen every sort of scheme and selfish ploy in this world, this was—
"…Isn't this a bit too much trust?"
Before he could say more, Rin snatched the scroll from his hands.
"Father! What kind of nonsense is this?!"
Her voice cracked, half from disbelief, half from rising emotion. Cheeks flushed bright red, Rin practically shouted at her father.
"You were going to give Sakura away before! I thought you changed after Brother Daemon destroyed the Matou family, but now you're handing all of us off like—like we're burdens?!"
Tokiomi said nothing. He kept his eyes down, lips pressed into a thin line. Silent guilt clung to him like a second coat.
Surprisingly, Sakura didn't look upset. In fact, the softest trace of hope shimmered in her eyes. She took a small step toward Daemon without realizing it, like a flower turning toward light.
To her, this wasn't abandonment. It was salvation.
Before Rin could explode further, the workshop door creaked open.
An elegant woman in a soft green dress entered with gentle footsteps. Her presence brought immediate calm, as if the wind itself had softened.
"Rin," Aoi Tohsaka said quietly, "this was your father's decision—and mine. It's not giving up… It's our last measure of safety, for you and Sakura."
She didn't look at Daemon. Not once. Her eyes remained on her daughter as she gently brushed a hand through Rin's hair.
"Please don't blame him. Try to understand."
Rin bit her lip. Her small fists clenched at her sides.
"…Do you really think… the Tohsaka family will fall that far?" she asked quietly, her voice wavering.
"It's not certain," Tokiomi said, finally lifting his eyes. "But it is a possibility. The Holy Grail War is far from predictable."
His tone became firmer as he continued.
"I'll be summoning a king—an ancient one. Even so, nothing is guaranteed. My duty as your father is to prepare for every outcome."
His eyes turned to Daemon, and his words slowed.
"And if I lose… I believe there is no better guardian for my daughters than you."
Daemon blinked. The hell is this? Is he… making me the heir of the Tohsaka family?
And this wasn't a trap. He could tell. No twisted magical clause, no underhanded scheme.
Just… blind trust.
"Even if I were a villain," he muttered to himself, "you'd still leave me your whole damn estate?"
Tokiomi's lips curled into a small smile.
"I've seen how you treat Sakura. You're no villain in her eyes. That's enough for me."
You old fool…
Then, without warning, Rin stepped forward.
"Fine. If that happens, then I'll be the head of the Tohsaka family."
Daemon looked down. The little girl's voice was small but proud, her eyes still shimmering with tears—but clear, determined.
"I'll protect my sister. I'll protect my mother. And if you'll help us, Mr. Daemon… please sign it."
She held the contract back up to him, arms stretched and hands slightly trembling.
"…Please."
Daemon stared at her for a long moment.
Then—he smiled.
