Location Underworld Phenex estate
The grand ballroom of the Phenex estate glittered like a thousand stars had been plucked from the sky and mounted onto the chandeliers. Nobility from across the Underworld filled the massive hall, voices low with forced excitement, each person pretending not to notice the stiff posture of the bride-to-be.
Rias Gremory stood adorned in an elegant white wedding gown, her crimson hair flowing like wildfire down her back. Her eyes, though painted and poised, betrayed a storm. She smiled, but it didn't reach her soul.
Riser Phenex smirked beside her, basking in the praise of his peers. Dressed in white and gold, the heir of House Phenex exuded confidence, arrogance, and self-importance. He looked at Rias not as a bride, but as a prize already won.
The priest raised the ceremonial script. "If there are any objections—"
The doors burst open.
A bright red magic circle flared across the floor, sending shockwaves through the chamber. From its center emerged Hyoudou Issei, dressed in his school uniform, out of breath and shaking with emotion.
"I OBJECT!"
Gasps filled the ballroom. The murmurs of nobles turned to scandalized whispers.
"Issei…" Rias whispered, stunned.
"I'm here to take Rias back!" he shouted, fists clenched, fire in his eyes. "You can't marry her, not like this! She doesn't want this!"
Riser stepped forward, laughing dismissively. "This pathetic human again? Didn't I already beat you? Stay down, you insect."
As gaurds began to charge over to him the rest of the gremory peerage arrived to his aid.
Ara~ Ise-kun so manly...
You're late Ise kun...
Dramatic pervert sempai…..
"Why you, you ungrateful little pricks….
Grayfia passed a knowing smile to Sirzechs and as they started to follow with their plan to have issei challenge Riser it happened.
Everything changed.
The temperature dropped.
The lights above flickered. The laughter and gasps died into silence. An unnatural pressure settled over the ballroom like a boulder crushing every chest.
Even Issei staggered.
A dark mist began to curl in from the far edges of the hall. Not black—but a deep, royal purple. It crawled across the floor like a living thing, climbing the marble pillars and swallowing the light.
From that mist came footsteps. Measured. Heavy. Each one echoed louder than the last.
The nobles backed away. A few even activated protective spells on instinct.
Sirzechs turned his head slowly, eyes widening, lips parting in disbelief. For the first time in centuries, the Crimson Satan looked shaken.
From the heart of the fog stepped a man.
He wore a black two-piece suit, pristine and sharp. A crimson undershirt peeked from beneath the jacket, blood-red and defiant. A black tie sat neatly against his chest. But what drew all eyes was the sword-shaped badge—glowing faintly in royal purple—pinned to his right breast pocket.
His hair was slicked back, and his eyes—gods, those eyes—were cold and sharp enough to pierce diamonds. They swept across the room like a scythe searching for a harvest.
He walked forward slowly, confidently, ignoring the chaos around him. Like he owned the place. Like he'd been waiting for this moment for far too long.
The mist dissipated behind him, revealing a path no one dared block.
But when they saw who it was Instead of awe, laughter followed.
"Isn't that... the Gremory's failure?"
"He disappeared twenty years ago. Must've crawled out of whatever hole he was hiding in."
"Why is he here?"
The nobles mocked openly, their jeers cutting into the stillness. A few chuckled behind jeweled goblets, unaware of the man's silence—that deadly calm reserved only for storms.
Sirzechs stood slowly. His eyes, initially wide with recognition, narrowed with a mix of frustration and relief.
"Atis... You're late."
Atis Gremory stopped before the altar, his gaze flicking over to Rias, who stared at him like a woman drowning had glimpsed a hand reaching from the water.
He smiled softly and hugged her whispering "You look beautiful, Rias. Too beautiful for this ocassion."
"You could've told me when you were arriving," Sirzechs muttered under his breath.
"You invited me. And if I had told you the dramatic flair wouldn't be there ," Atis replied casually. Hugging his brother and giving Grafiya a two finger salute which she surprisingly returned.
Sirzechs sighed and rubbed the bridge of his nose.
Atis turned to the crowd. "A toast to the future lord and lady Phenex! I am glad to have you as my Brother in law." Atis said shaking Riser's hand.
"I heard about you Atis a genius born once in a lifetime but still gave up on your position, you're someone I deeply respect." Riser said surprisingly diplomacy in his tone.
Murmurs rose.
He smirked at Riser. "Lord Phenex, you radiate such strength. Your aura, your flame—it's intoxicating. To stand here in your presence, I feel honored. Surely, a devil of your prowess would relish the chance to showcase his power in a rating match."
Riser puffed up instantly, his ego ballooning. "You recognize true power. That's what I expected from a genius of your caliber."
Atis tilted his head politely. "Then perhaps you would indulge me. A proper match—me , against you."
"Wouldn't that be a bit unfair to Riser, although a dropout you are an ultimate class devil nevertheless."
"Then how about me vs your entire peerage" Riser smirked at this. Atis was an Ultimate class but he was a mage not a fighter like riser his talents lay in academics not fists.
Outrage swept the hall.
"This is madness!"
"An insult!"
Sirzechs raised a hand. "Enough. Atis you really wish to go through this" He asked a bit worried about his brother. Atis noded.
Sirzechs nodded toward Azuka, who gave a sigh.
"I'll set the stage," Azuka said. A snap of his fingers and a complex magic circle opened beneath the ballroom. The floor warped and twisted, bending reality. —Riser his peerage and Atis,—were transported to a pocket dimension, crafted for one purpose: battle.
"Ok the rule of this game are simple If the king is defeated the game is over there is no time limit and the participants may began in five minutes." The voice of Grafiya transpoted through the speakers a bit of anticipation in her voice.
In midst of all Issei was left standing his thunder stolen but was consoled by Rias who gave him a little headpat for his bravery.
