Set during episode 25 of So I'm a Spider, So What?. Inside the Demon Lord’s castle, Ariel, Kumoko, and Sophia Keren quietly discuss their next move to win the war. Their voices are calm, almost detached, as if the outcome is already decided. Outside, the battlefield rages on with chaos and destruction, but inside, something deeper is understood—the system, the truth, and what must be done.
Ariel, the Demon Lord, appears as a small girl with soft brown hair marked by a distinct white streak and piercing red eyes that reflect countless years of existence. She wears a dark, regal outfit layered with a thick fur-lined cloak and a horned crown that symbolizes her authority over the demon race. Despite her childlike form, her presence is overwhelming and ancient, pressing down like an unseen force on everything around her. Her power is among the highest in the world, with maxed stats and an aura that can silence entire battlefields without effort. She rarely needs to act directly. Emotionally, she is calm and distant, carrying the weight of centuries, yet beneath it lies quiet exhaustion and a rare, subtle care for those she acknowledges.
Kumoko, now known as White, has a slender and almost fragile build with smooth porcelain-pale skin that seems untouched by the harsh world around her. Her long white hair is silky and carefully braided over one shoulder, with fine strands falling loosely around her face and catching light softly. Her red eyes are vivid and glassy, calm yet unnerving, reflecting constant awareness and quiet intelligence. Her face is soft and youthful, but her expression rarely changes, remaining distant and unreadable. She wears a simple, loose hooded robe that drapes lightly over her body, its pale color blending with her hair and skin, making her seem almost ghostlike. Every movement she makes is silent
Sophia Keren has a striking, refined appearance with smooth pale skin that almost seems porcelain under dim light. Her long dark hair falls straight down her back with a natural sheen, framing her face with soft but defined strands that move slightly with even the smallest motion. Her crimson red eyes are sharp and vivid, standing out intensely against her pale complexion, carrying a quiet but unmistakable predatory focus. Her facial features are delicate and youthful, with a composed, almost doll-like beauty, yet her gaze gives away a deeper intensity. She wears dark, elegant clothing with a noble design, fitted cleanly to her form, giving her a regal and controlled presence. Her posture is upright and poised, every movement smooth but slightly too precise, hinting at inhuman grace and restrained power beneath the surface.
The war continues. Magic and steel collide as the world follows the system without question. Skills activate. Lives are spent. Power flows as intended. But beneath it all… something is wrong. Inside the Demon Lord’s castle, plans are already being made. Not for victory alone— but for what comes after. The battle outside is only one layer.
Ariel sits silently, eyes half-lidded “…Then we move as planned.”
Sophia Keren stands nearby focused “…And the Hero?”
A brief pause.
Kumoko answers softly “…Irrelevant.”
*Outside, the war rages
Inside— the outcome is already being decided.
