Part I:
The grand council chamber of the Underworld was silent except for the quiet sobbing of Rias Gremory. She sat in a high-backed chair, still in her torn and burned battle attire, refusing to change. Her crimson hair was disheveled, ash-streaked, her face pale.
Beside her, Akeno stood with a hand on her King's shoulder, her own expression carefully neutral despite the fury burning in her eyes.
Around the circular table sat the power players of devil society:
Sirzechs Lucifer, looking unusually serious in his full Satan regalia, hands steepled in front of his face.
Lord Zeoticus Gremory, his expression grim, aged in a way that suggested he'd been arguing for hours.
Lady Venelana Gremory, her usual grace replaced with maternal worry as she watched her granddaughter fall apart.
Lord and Lady Phenex, Riser's parents, looking satisfied in that smug way that came from winning a political negotiation.
Riser Phenex himself, lounging in his chair with a wine glass, looking every inch the victorious groom.
And
Grayfia Lucifuge, standing behind Sirzechs as always, her maid uniform immaculate, her face an unreadable mask. But her hands, clasped behind her back, were trembling.
"The matter is settled," Lord Phenex said, his voice booming with finality.
"The Rating Game was completed. Riser won. The marriage contract stands. The wedding will proceed in three days as agreed."
"No."
Rias's voice was small but firm.
"No, I won't—I can't—"
"You agreed to the terms!" Lady Phenex snapped.
"You challenged for your freedom and lost! You can't back out now!"
"I don't care about the contract! I don't care about politics! I won't marry him!" Riser sipped his wine.
"Darling, this tantrum is unbecoming. You lost fairly. Accept it with grace."
"GRACE?!" Rias's head snapped up, tears streaming down her face.
"You want me to gracefully accept being sold like property?! To spend eternity with someone I don't love?!"
"Love?" Riser laughed.
"We're devils, darling. Love is a human concept. We deal in power, alliance, bloodline—"
"I don't CARE!" She stood, power crackling around her.
"I won't do it! I'll run away! I'll renounce my family! I'll—"
"You'll do no such thing," Zeoticus said heavily.
"Rias, please. Be reasonable. The contract—"
"Damn the contract!"
"RIAS!" Sirzechs's voice cracked like a whip. Everyone froze. The Crimson Satan stood, and for a moment, the playful mask he usually wore was completely gone. This was Sirzechs Lucifer—one of the Four Great Satans, the strongest devil alive.
"I understand you're upset," he said quietly. "I understand you feel trapped. But this is bigger than your feelings. This is about House Gremory's standing. About the alliance between our families. About—"
"About everything except me," Rias whispered.
"About everything except what I want. What I need. What I—" Her voice broke.
"I thought you'd understand. You married for love. You chose Grayfia despite the politics. Why can't I—"
"Because I was already a Satan," Sirzechs said, his voice pained.
"I had the power to make that choice. You don't. Not yet."
"So, I'm just... property? To be traded?" Silence.
Venelana stood, walked to her daughter, and pulled her into an embrace. Rias collapsed against her, sobbing.
"There has to be another way," Venelana said, looking at Sirzechs.
"Some loophole. Some—"
"There isn't," Lord Phenex said firmly.
"The contract is ironclad. Either Rias Gremory marries our son, or House Gremory pays a penalty so severe it would cripple your family for generations."
"How much?" Zeoticus asked quietly.
"Three hundred thousand Phoenix Tears. Fifty percent of your liquid assets. And the immediate cessation of all trade agreements between our houses."
The number was astronomical.
Devastating.
Venelana's face went pale.
"That's... that's economic warfare."
"That's the price of breaking a sacred contract," Lady Phenex replied coolly. Riser set down his wine glass.
"Or—" He smiled. "—my beautiful fiancée could simply accept reality and marry me. I promise I'll be a... generous husband." The way he said "generous" made Rias's skin crawl.
"Never," she whispered.
"I'd rather die."
"Don't be dramatic—"
"I MEAN IT!" She pulled away from Venelana, power surging.
"I'll do it! I'll kill myself before I marry you! At least then I'd have SOME control over my life!"
"Rias, no—" Sirzechs started. But she was already gathering the Power of Destruction, pointing it at her own chest— Grayfia moved. Faster than anyone could track, the Strongest Queen appeared beside Rias and struck her hand, dispersing the magic.
"Enough," Grayfia said quietly.
"This solves nothing."
"Then WHAT DOES?!" Rias screamed at her.
"What solution is there?! I lost the Rating Game! The contract stands! I have no power, no options, no—" The door to the council chamber burst open.
Everyone turned.
And standing in the doorway, looking like he'd just walked through hell, was someone who should NOT have been there. Lucien Gremory.
Part II:
Lucien looked terrible. The perfect golden boy of House Gremory was disheveled, his crimson hair messy, his expensive suit rumpled, dark circles under his eyes. He was breathing hard, like he'd run the entire way here. Behind him, looking equally exhausted, was Seekvaira Agares, his Queen and fiancée.
"Lucien?" Zeoticus stood.
"What are you doing here? You're supposed to be in the Rating Game tournament—"
"I forfeited," Lucien said bluntly.
Silence.
"You... forfeited?" Zeoticus's voice was dangerously quiet.
"Do you have ANY idea what that does to House Gremory's reputation? The embarrassment? The—"
"I don't care." Lucien walked into the room, his golden eyes—usually so confident—now filled with something like shame.
"I heard what happened. The Rating Game. Rias losing. The marriage."
He looked at his aunt—, younger, because devil family trees were weird—and his expression crumpled.
"I should have been there," he said quietly.
"I should have helped. But I was too focused on my own glory, my own tournament, my own—" He laughed bitterly. "I'm a terrible."
"Lucien—" Rias started.
"No, let me finish." He turned to face the Phoenix family.
"Lord and Lady Phenex. Riser. I formally challenge the marriage contract." Riser's eyebrows rose.
"On what grounds?"
"On the grounds that Rias Gremory is MY family, and I won't let her be sold to someone she despises."
"How touching," Riser drawled.
"But legally meaningless. You have no standing to challenge—"
"Then I'll challenge YOU," Lucien said, power beginning to gather around him.
"Another Rating Game. Me versus you. If I win, the contract is void."
"If you lose?"
"Then I'll pay the penalty myself. My personal fortune. My territory. Everything I own." Gasps around the table. Seekvaira put a hand on his arm.
"Lucien, that's—"
"Worth it," he said firmly.
"She's a child." Riser studied him for a long moment.
Then laughed.
"How noble! How heroic! The golden prince, sacrificing everything for his beloved aunt!" He stood, wings of flame manifesting.
"I accept. Let's schedule it for—"
"No," Lord Phenex interrupted. Everyone turned to stare at him.
"Father?" Riser looked confused.
"I said no." The elder Phenex's expression was cold.
"You've already won one Rating Game today, Riser. Your power is proven. The contract stands. We will NOT risk it on your arrogance again." "But—"
"ENOUGH." Lord Phenex's voice boomed.
"The matter is closed. Rias Gremory will marry you in three days. This discussion is over." Lucien looked like he'd been slapped.
"But I'm offering everything—"
"Your offer is refused. Sit down."
Part III:
The door opened again.
This time, no one was surprised. Because standing there, looking like winter personified, was Caelan Lucifuge.
He walked into the council chamber with that same detached calm he always wore, Hoarfrost padding beside him, frost forming on the marble floor where he stepped.
"Oh good," he said flatly.
"Everyone's here. This will be efficient." Sirzechs stood.
"Caelan. This is a private—"
"Family matter. Yes. I'm aware." Caelan's silver eyes swept the room. "I'm family. Technically. So, I'm involved."
"You have no standing in this negotiation—"
"I have a solution." That stopped everyone. Grayfia's eyes widened slightly. Rias looked up, hope flickering in her expression. Even Riser looked curious.
"What solution?" Zeoticus asked cautiously. Caelan walked to the center of the room, standing directly across from the Phoenix family.
"The contract states that Rias Gremory must marry into House Phoenix to solidify the alliance between your families. Correct?"
"Yes," Lord Phoenix confirmed.
"But it doesn't specify WHICH Phoenix she must marry." Silence.
"What are you saying?" Lady Phenex asked slowly.
"I'm saying—" Caelan looked directly at Riser. "—that Riser Phoenix isn't the only option. He has a sister."
All eyes turned to Ravel Phenex, the young blonde who'd been sitting quietly in the corner throughout this entire debacle.
She squeaked.
"M-me?!"
"You're a Phoenix. You're of marriageable age. And—" Caelan's expression didn't change. "—you're far less objectionable than your brother."
Riser shot to his feet.
"Are you suggesting my SISTER marry Rias?! That's—that's—"
"Politically sound. Devils don't care about gender in marriages. Alliances are alliances." Caelan tilted his head.
"Unless the Phoenix family is so traditionalist that they'd refuse a perfectly valid arrangement?" Lord Phoenix stroked his beard, looking thoughtful.
"An... interesting proposal. But Ravel is young. Inexperienced. The point of this marriage was to secure a strong alliance—"
"Then strengthen it differently," Caelan interrupted.
"House Phoenix gets a marriage into House Gremory. House Gremory gets to avoid forcing their daughter into a union she despises. Everyone wins."
"Except me," Riser said coldly.
"I won the Rating Game. Rias is MINE."
"The contract says she must marry a Phoenix. It doesn't say she must marry YOU." Caelan's smile was sharp.
"Read your own paperwork."
Lawyers were summoned. Ancient scrolls were unrolled. And after thirty minutes of intense legal review— "He's... he's correct," one of the lawyers admitted. "The contract specifies 'a union between House Gremory and House Phenex through marriage.' It doesn't name Riser specifically." Lord Phenex's eyes narrowed.
"You crafty little—"
"I prefer 'thorough,'" Caelan replied.
Riser's face was turning red. "This is RIDICULOUS! I won! I earned her! You can't just—"
"Actually," Grayfia spoke up, her voice cutting through the chaos,
"Lord Lucifuge's interpretation is legally sound. If House Phoenix agrees to substitute Ravel for Riser, the contract would still be fulfilled." Sirzechs was staring at Caelan with something like awe. "You... you actually found a loophole."
"I found the obvious solution that everyone else ignored because they were too focused on tradition." Caelan looked at Rias.
"Do you find Ravel objectionable?" Rias looked at the young blonde Phenex, who was currently resembling a deer in headlights.
"I... I don't even know her that well," Rias admitted.
"Then get to know her. You have three days before the wedding." Caelan's tone was matter-of-fact.
"Worst case, you're married to someone your own age who isn't an arrogant ass. Best case, you might actually get along." Ravel found her voice.
"I—I wouldn't be opposed! Rias-sama is beautiful and powerful and—and I've always admired her from afar and—" She turned bright red. "I mean, if she'd have me, I'd be honoured!" Rias blinked.
"You... you'd actually want to marry me?" "More than anything!"
"But we barely know each other—"
"Then let's fix that!" Ravel stood, her earlier nervousness replaced with determined enthusiasm.
"Three days! We can spend three days getting to know each other! And if—if at the end you still can't stand me, then... then we'll figure something else out. But please! Give me a chance!" Rias looked at this eager, genuine young woman who was looking at her like she hung the moon. Then looked at Riser, who was glaring with entitlement and possessiveness.
The choice was obvious.
"Okay," Rias said.
"Okay, let's try." Ravel's face lit up like Christmas morning.
Riser exploded.
"FATHER! You can't POSSIBLY be considering this! I WON! The contract is MINE—"
"The contract belongs to HOUSE PHENEX," Lord Phenex said sharply.
"Not to you personally. And Lord Lucifuge is correct—the wording allows for this substitution."
"But—"
"ENOUGH, Riser." Lady Phenex's voice was ice.
"You've embarrassed yourself enough today. Sit. Down." Riser looked like he wanted to argue.
Then he saw his father's expression. And sat. Fuming.
Lord Phenex turned to Caelan. "You're quite clever, Lord Lucifuge. I don't know if I should be impressed or insulted."
"Be impressed. It's more productive." The faintest smile crossed the elder Phoenix's face.
"Very well. We accept the substitution. Rias Gremory will marry Ravel Phoenix in three days. The alliance stands." Cheers erupted from the Gremory side of the table. Rias collapsed back into her chair, looking like a weight had been lifted from her shoulders.
Lucien grinned, genuine happiness on his face for the first time in the meeting. Venelana was openly crying with relief. And Sirzechs— Sirzechs was staring at Caelan like he'd just witnessed a miracle.
"You saved her," he said quietly.
"I applied logic to an illogical situation," Caelan replied.
"Nothing miraculous about it."
"Still. Thank you." Caelan didn't respond.
But Grayfia, standing behind Sirzechs, was watching her son with an expression that was complex and painful and something that might have been pride.
Part IV:
Later that evening, after the council chamber had cleared and contracts had been rewritten and Ravel had dragged Rias off to "get to know each other properly," Grayfia found Caelan standing on the balcony outside the chamber. He was looking out at the Underworld's crimson sky, Hoarfrost sitting beside him.
"That was well done," Grayfia said quietly.
"It was obvious."
"To you, perhaps. Not to the rest of us." She stepped closer.
"You saved Rias from a lifetime of misery."
"I saved her from a bad marriage. Whether her life will be miserable is up to her and Ravel."
"You know what I mean." He was quiet for a moment.
"Why are you here, Grayfia?" The use of her name—not "Mother," never "Mother"—stung. But she'd earned that distance.
"I wanted to thank you. Personally."
"You already did."
"And I wanted to—" She struggled for words.
"I wanted to apologize. For everything. For how we treated you. For the neglect. For—"
"Stop." She stopped.
Caelan turned to face her, his silver eyes unreadable.
"Apologies require intent to change," he said quietly.
"Do you intend to change? To suddenly become the mother, you never were? To welcome me back into the family like the past twenty-three years didn't happen?" Grayfia opened her mouth. Closed it.
"I thought not," Caelan said.
"So keep your apologies. They're worthless."
"Caelan—"
"I helped Rias because she didn't deserve to suffer for politics. Because she's a decent person who's been trapped by circumstances she didn't create. Not because she's 'family.'"
His voice was cold.
"Don't mistake my actions for forgiveness."
"I'm not asking for forgiveness—"
"Then what ARE you asking for?" Grayfia met his eyes. And for the first time in twenty-three years, she was completely honest.
"I don't know," she whispered.
"I just—I see you. I SEE you now. And I realize I never did before. And I want—" Her voice broke. "I want a chance to know my son. Even if it's too late. Even if you hate me. I just want to TRY." Caelan stared at her for a long moment.
"You're right," he said finally.
"It is too late." He turned and walked away, Hoarfrost following. Leaving Grayfia standing alone on the balcony, tears finally falling from the Strongest Queen's eyes.
Part V:
Back at Rias's mansion, the entire Occult Research Club was gathered in the living room.
Everyone was there: Akeno, Kiba, Koneko, Asia, and Issei (who'd woken up from his retirement with a splitting headache and a newfound respect for Balance Breaker's limitations).
And Rias, sitting in the center of the sofa, looking shell-shocked. "So," Akeno said slowly, "you're marrying Ravel Phenex."
"Apparently."
"And you're... okay with this?"
"I mean—" Rias laughed, slightly hysterical.
"It's better than Riser! SO much better than Riser! But also—I'm getting MARRIED! In THREE DAYS! To a girl I barely know!"
"At least she's cute," Issei offered.
"THAT'S NOT THE POINT!"
"What is the point?" Koneko asked, munching cookies. Rias flopped backward on the sofa.
"I don't know anymore. My life is insane. Two weeks ago I was a normal high school devil. Now I'm married to a Phoenix heiress I've spoken to maybe twice."
"It could be worse," Kiba said gently.
"Ravel seemed genuinely happy about the arrangement." "She looked like I'd offered her the world," Rias admitted.
"Which is—it's sweet! It's genuinely sweet! But also TERRIFYING because what if I can't live up to her expectations?!" Asia patted her hand.
"You're wonderful, President. Anyone would be lucky to marry you."
"Thanks, Asia." Rias smiled weakly.
Then sat up.
"Wait. Where's Caelan?"
"He left right after the council meeting," Akeno reported.
"Said something about 'avoiding the emotional fallout' and teleported back to the Eastern Marches."
"Of course he did." Rias laughed.
"He saves my life and then immediately runs away from any gratitude."
"That's Sensei for you," Issei said.
"Cold bastard with a secretly warm heart."
"He'd freeze your dick off for saying that," Koneko observed.
"PROBABLY! But I'm RIGHT!" There was a knock on the door. Akeno opened it to reveal Ravel Phenex, looking nervous and hopeful, holding a bouquet of flowers.
"Um," the blonde said.
"Hi. I know it's late, but I thought—maybe we could talk? Get to know each other? Since we're, um, getting married?" Rias stared at her.
Then started laughing. Not hysterical laughter. Just... genuine, relieved laughter.
"Yeah," she said, standing.
"Yeah, let's talk. Come in." Ravel's face lit up, and she practically skipped inside. The Occult Research Club watched as their President and her future wife disappeared into the study to "get to know each other."
"Ten bucks says they're making out within an hour," Akeno said.
"I'm not taking that bet," Kiba replied.
"Ara ara~"
Part VI:
Caelan was in his study, reviewing financial reports, when the teleportation circle flared. He looked up, mildly annoyed, expecting Rias or maybe Grayfia.
Instead, Lucien Gremory stepped through.
His brother. Or twin-brother. Or—whatever.
"What," Caelan said flatly. Lucien looked around the study—elegant, cold, lined with books and magical artifacts.
"Nice place."
"I'm busy."
"I can see that." Lucien walked closer.
"I won't take much of your time. I just wanted to say—" He took a breath. "Thank you. For saving Rias." "
I didn't save her. I applied contract law."
"You saved her," Lucien insisted.
"I tried to fight for her and got shut down. You found a legal loophole and got her out. That's—" He laughed.
"That's brilliant. I should have thought of it."
"You were too emotional. Emotion clouds judgment."
"Maybe. But at least I felt something." Lucien's voice was quiet.
"At least I cared enough to try." Caelan's eyes narrowed.
"What's that supposed to mean?"
"It means—" Lucien sat down uninvited.
"It means I've been a shit brother. whatever we are. I don't even remember you from when we were kids. How fucked up is that? We shared a womb, and I don't remember you existing."
"You were a kid."
"I was not when I finally learned you existed at all." Lucien's voice was bitter.
"I overheard servants talking about 'the other twin' and I thought they were joking. Then I asked Father and he got this—this LOOK on his face. Like I'd mentioned something embarrassing. And he just said 'your brother lives in the Eastern Marches' and changed the subject."
Caelan said nothing.
"I should have pushed," Lucien continued.
"I should have demanded answers. I should have—" He laughed bitterly.
"I should have been a better brother. But I didn't. Because it was easier not to. Easier to just focus on my training, my peerage, my glory. And you were just—this abstract concept. The 'other twin' who didn't matter."
"I didn't matter because I was weak," Caelan said.
"That's how devil society works. Power equals worth."
"That's BULLSHIT!" Lucien's power flared.
"You're not weak! You built a territory! An economic empire! You outsmarted everyone in that council chamber! You're—" He struggled for words.
"You're incredible. And I—I'm just the lucky asshole who was born with the Power of Destruction." Silence.
"Why are you here, Lucien?"
"Because—" Lucien met his eyes.
"Because I want to know my brother. Is that so wrong?"
"Yes."
"Why?"
"Because you're twenty-three years too late." The words hung in the air like a death sentence. Lucien flinched.
"I know. I know I fucked up. But—can't we start now? Can't we—"
"No."
"Why not?!"
"Because I don't need a brother," Caelan said quietly.
"I don't need family. I don't need any of you. I stopped needing you the day I realized I was invisible."
"You're not invisible—"
"I was. For years, I was a ghost in my own family. And I learned to live with that. I learned to thrive in isolation. And now you want to come back and—what? Play happy family? Pretend the past didn't happen?"
"I'm not asking you to forget—"
"Then what ARE you asking?" Lucien opened his mouth. Closed it.
"I don't know," he admitted.
"I just—I don't want to be strangers anymore." Caelan looked at him—really looked at him. Saw the genuine remorse. The hope. The desperate need for connection. And felt... nothing.
"We are strangers," he said finally.
"We always have been. And a five-minute conversation doesn't change that."
"But it's a start—"
"No. It's too late." He stood, walked to the door, and opened it.
"Leave." Lucien didn't move.
"Caelan—"
"I said leave." For a long moment, Lucien sat there. Then he stood, walked to the door, and paused.
"For what it's worth," he said quietly,
"I'm proud to be you brother. Even if you don't feel the same." He left.
Caelan closed the door. Stood there for a moment.
Then went back to his desk and returned to his financial reports. As if nothing had happened.
Part VII:
The Phoenix family estate was decorated for a wedding. Not the grand, ostentatious affair that had been planned for Riser and Rias.
But something smaller.
More intimate.
More... personal.
Rias stood in the bride's chamber, wearing a beautiful white dress that Venelana had insisted on, looking nervous and beautiful and terrified.
"I can't believe I'm doing this," she muttered.
Akeno adjusted her veil.
"You look stunning, President."
"I look like I'm about to throw up."
"That's normal for weddings!" Asia said cheerfully. Koneko handed her a cookie.
"Eat. You're shaking." Rias took it gratefully. There was a knock on the door. Grayfia entered, looking elegant in her formal attire.
"It's time," she said gently. Rias took a deep breath.
"Right. Time to get married. To a girl I've known for three days. This is fine. Everything is fine."
"You don't have to do this," Grayfia said quietly.
"Even now. If you truly can't—"
"No." Rias squared her shoulders.
"I made my choice. Ravel is—she's sweet. She's genuine. She looks at me like I'm amazing. And honestly?" She smiled.
"I could do a lot worse."
"You could have Riser," Akeno pointed out.
"EXACTLY. See? Perspective!" They walked to the ceremony hall. It was beautiful—decorated with flowers, magical lights, filled with devils from both families. And at the altar, wearing a stunning white suit, stood Ravel Phenex.
She looked up as Rias entered. And her face lit up with pure joy. Rias felt something in her chest warm.
Maybe this won't be so bad after all.
The ceremony was brief. Traditional devil vows.
Exchanging of rings. The binding of their magical signatures. And when the officiant said "you may kiss the bride"—
Ravel kissed Rias with such genuine happiness that the entire hall erupted in applause.
Rias kissed back. And thought: Yeah. This is going to be okay.
In the back of the hall, Caelan stood alone, watching.
He'd come because Rias had personally asked him to.
Because she'd looked at him with those hopeful eyes and said "please, you saved me, the least you can do is watch me get married." So here he was.
Watching his aunt marry a girl she barely knew to escape a worse fate.
"Beautiful ceremony," a voice said beside him.
He turned to find Grayfia, also watching from the back.
"It's adequate," he replied.
"You came."
"Rias asked."
"You could have said no."
"I could have."
They stood in silence.
"Thank you," Grayfia said quietly.
"For everything. For saving her. For—"
"Stop thanking me. I didn't do it for you."
"I know." She was quiet for a moment.
"Can I ask you something?"
"You will anyway."
"Do you think—" She struggled for words.
"Do you think there's any chance? For us? For our family? To ever be—"
"No."
The word was final. Absolute.
Grayfia's face crumpled, just slightly. "I see," she whispered. Caelan looked at her. Really looked at her.
"You want absolution," he said quietly.
"You want me to forgive you so you can stop feeling guilty. So you can tell yourself 'I tried' and move on with your life feeling like you did everything you could."
"That's not—"
"It is. And I won't give it to you. You abandoned me. You forgot I existed. And now you want me to make you feel better about it?" He shook his head.
"No. Live with the guilt. You earned it." He walked away. Leaving Grayfia standing alone in the back of the wedding hall, tears streaming down her face.
The reception was loud and joyful.
Rias and Ravel were dancing, laughing, looking genuinely happy.
The Occult Research Club was celebrating.
Even Riser, sulking in a corner, couldn't dampen the mood.
And Caelan Lucifuge stood on a balcony, watching it all from a distance.
Alone.
Always alone.
"You did good, little king," Khione whispered.
"I did what needed to be done."
"You saved her."
"I applied logic."
"You cared."
"I didn't."
"Liar."
He didn't respond.
Below, Rias looked up, caught his eye, and smiled. Mouthed: Thank you.
He nodded once.
Then teleported away.
Back to the Eastern Marches. Back to his cold, empty mansion.
Back to the life he'd built in isolation.
Because that's what he was.
The King of Winter.
Alone in his frozen kingdom.
And he told himself he preferred it that way.
