A Campione – a Godslayer – is calamity incarnate.
Where they tread, myths awaken, authorities clash, and the fragile masquerade that hides the supernatural from mortal eyes frays at the edges.
To the devils of the Underworld, they are walking apocalypses wrapped in human skin — tyrants who bow to no Satan, no Maou, no ancient pact. Their very existence mocks the Great War's fragile armistice, for what use are alliances between devils, angels, and fallen when a single mortal can slay divinities and claim their thrones?
Yet even calamity has patterns. The seven known Godslayers have territories, habits, whims that can be mapped, predicted, avoided. One does not lightly provoke the Hunter of the Balkans, the Martial Emperor of China, the Wandering Queen of Time, or the Sword King of Italy. To do so invites ruin not just upon oneself, but upon entire bloodlines.
Rias Gremory, heiress of the Gremory clan, knew this better than most. She had studied the sparse records her brother Sirzechs allowed her to see — the hushed reports from the Grigori, the wary missives from the Church, the grudging acknowledgments from the Youkai of Japan. A Campione was not an enemy one fought; they were a storm one survived.
So when the first alerts reached Kuoh — anomalous divine energy spiking over the Indian Ocean, then vanishing without trace near Japanese waters — Rias felt the familiar chill of impending chaos.
She stood alone on the rooftop of Kuoh Academy as dusk bled into night, crimson hair whipping in the wind. Below, the Occult Research Club room lights flickered; Akeno would be preparing tea, Kiba polishing his sword, Asia murmuring prayers, Issei… probably peeking at something he shouldn't. Normalcy. Precious, fleeting normalcy.
Her phone vibrated. A secure line from the Underworld.
"Report confirmed," Grayfia's voice stated, cool and precise. "The disturbance matches the signature of a Heretic God's manifestation. No residual energy, no divine corpse, no territorial claim staked. It simply… ceased."
Rias's grip tightened on the railing. "A Campione?"
"Unknown. But the location points to Japan. If one of the seven acted outside their domain — Luo Hao, perhaps, or Doni in one of his impulsive duels — the others will notice. If not… then we may be witnessing the birth of an eighth."
An eighth.
The word hung like a guillotine. The last new Campione — Kusanagi Godou — had appeared years ago, and even he had stabilized into a reluctant guardian of balance. A new one, untested, unchecked, rising in Japan of all places…
Rias thought of her peerage. Of Issei's growing power, Asia's innocence, Koneko's quiet scars. Of the Rating Games, the Khaos Brigade threats, the endless politics. They had enough enemies without adding an unpredictable Godslayer who could rewrite reality on a whim.
"Grayfia," she said quietly. "Inform Onii-sama. Discreetly. And… prepare the Phenex and Bael contacts. If this new force emerges here, Kuoh will be at the center."
A pause. Then, "Understood, Lady Rias. Be cautious. The birth of a Campione is rarely gentle."
The call ended. Rias exhaled, watching the city lights glitter below like fragile stars.
In the supernatural undercurrents of Japan, something ancient and terrible had stirred — and been silenced before it could fully awaken.
Whatever — or whoever — had done the silencing was now the unknown variable.
And variables, in Rias's experience, were rarely kind to devils.
She turned toward the stairs, resolve hardening in her violet eyes.
If a new Demon King had risen on her doorstep, she would meet them not as prey… but as a devil who bowed to no one.
Let the storm come.
She would be ready.
