You were just a normal student—until Day 0, when a serial killer ended your life in a dark alley. But your soul didn’t rest. On Day 1, beneath a crimson moon, you awoke inside a demonic summoning circle, reborn by Rias Gremory herself—noble, breathtaking, and terrifying—who claimed you as her Knight, binding your soul to her crimson magic. Through Weeks 1 to 4, you trained fiercely with the Gremory peerage: Issei, reckless and passionate, whose determination made him stronger every day; Akeno, sadistic but soft-hearted, guiding you through your power; Kiba, calm and graceful, who taught you the way of blades and loyalty; and Koneko, silent and sharp, whose neko instincts hid both pain and tenderness. You became part of something. A family. But by Month 2, everything shattered—your Sacred Gear, unstable and overflowing, evolved mid-battle, releasing a catastrophic surge of crimson and black energy. The team was decimated: Issei barely clung to life, Kiba was buried under rubble, Akeno collapsed and scorched, and Koneko, her neko blood flaring, lay trembling on the edge of death. Desperate to survive, Koneko instinctively latched onto Akeno’s chest, drawing demonic milk to heal her broken body. When Akeno weakened, Rias—elegant and commanding—stepped forward, offering herself without hesitation, letting Koneko feed. You reached out in horror and guilt—but glowing chains erupted beneath you. “You’re too dangerous,” Rias whispered, her voice cracking as she sealed you in a void of darkness, your power, memories, and will locked away. By Month 3, as you remained sealed, Diodora Astaroth struck. He kidnapped Asia Argento, declaring she had always belonged to him, mocking her kindness and twisting her memories. But the Gremory peerage would not let that stand. On the Day of Reckoning, the full team stood together—Issei, aura blazing with fury; Rias, regal and furious, her magic flaring like a queen’s wrath; Kiba, sword drawn with knightly vengeance; Akeno, recovered and deadly, electricity crackling at her fingertips; Xenovia, divine blade ready; Irina, righteous and fierce; and even Koneko, now stabilized, her golden eyes focused with silent rage. Asia cried for help… and Diodora turned to mock you, still sealed. That mockery broke something. Your name—Jono—ignited in the void, and the seal shattered. You descended like a meteor, clad in controlled chaos, standing between Asia and her captor. Just then, Riser Phenex appeared, wings of fire outstretched, still bitter about his defeat by Rias. “Let’s see if your knight can survive this,” he taunted. But before his flames struck, shadows swept the room—Cid Kagenō emerged, a figure from another world, smiling coolly. “I am the one who lurks in the shadows,” he whispered, nullifying Riser’s flames with a flick of his hand. As if summoned by fate itself, Sirzechs Lucifer descended, his power radiant and absolute. “Enough,” he commanded, red hair glowing with divine authority. “This ends now—or it becomes a war.” Chaos erupted. You clashed with Diodora in a storm of energy and vengeance. Issei faced Riser once more, evolved and unrelenting. Cid dismantled barriers and illusions as if they were paper. The rest of the Gremory team—Rias, Kiba, Akeno, Koneko, Xenovia, Irina—fought as one, a unit forged in loyalty and fire. And when the dust settled, Diodora was crushed, Riser humiliated again, and Asia safe in Rias’s arms. You stood tall, power controlled, no longer a threat—but their strongest shield. Rias met your eyes, not with fear, but pride. Sirzechs gave a solemn nod. Even Cid paused, intrigued. The Crimson Knight had returned—and the world of devils, angels, and shadows would never be the same.?
