The credits for Demon Slayer Season 4 rolled, leaving you a sobbing mess on your desk. The angst was visceral, the animation was a masterpiece, and your heart was effectively shredded. Naturally, there was only one way to cope: Character Design.

You spent the next hour pouring that emotional damage into a new OC. You’d just finished the line art—cursing the existence of symmetrical eyes—when a thunderous CRASH echoed from downstairs.

Your parents weren't due back for hours. Heart hammering against your ribs, you crept toward the landing. You had zero combat training and a shaky grip on a mechanical pencil, but curiosity won.

Peeking over the bannister, your breath hitched. Splayed across your rug were three figures that shouldn't exist: Kokushibo, Douma, and Akaza.

They looked terrifyingly real. Every mark, every blade, every ounce of oppressive aura was present. Naturally, because you lacked a single lick of survival instinct, you didn't call the police. You went down to get a closer look.

You were hovering over Akaza, marveling at the pink gradient of his hair, when Douma’s fan-like eyelashes fluttered. You bolted, diving behind the hallway wall just as he sat up.

"My, my..." Douma’s voice was like honey poured over glass. "Where have we drifted to?"

He didn't seem bothered. He never was. He leaned over and gave Akaza a playful shove. "Akaza-dono! Wakey-wakey! You’re missing the scenery!"

A few minutes of chaotic waking later, the air in your living room felt heavy enough to crack the floorboards.

Akaza: "Identify this place! Is this a Blood Demon Art? An illusion?!" He was already in a crouch, blue markings glowing faintly in the dim light.

Douma: "Oh, relax, Akaza-dono! If it’s an illusion, it’s a very comfortable one. Look at this 'sofa'!"

Akaza: "Shut your mouth before I tear it off your face."

**Kokushibo:*" "Enough."

The eldest demon’s voice acted like a physical weight, silencing them instantly. His six eyes scanned the room with terrifying precision before settling on the hallway. "Stop the bickering. We are being watched. There is a human... nearby."

Douma: "A human? Oh, I hope it’s a lady. I'm famished after that trip..."

Akaza: "Disgusting pig."

Kokushibo: "Come out, human. Hide-and-seek is for children."

Realizing your "stealth" was useless against the highest-ranking demons in existence, you slowly stepped into the light. Your knees were shaking, but your artist's brain was still screaming, 'The shading on his kimono is incredible!'

Kokushibo’s six eyes tracked your every movement, making your skin crawl. "Did you... summon us here?"

You shook your head frantically, unable to find your voice.

Douma: "So, what’s the plan? Do we eat them now, or...?"

Kokushibo: "No. Not yet. This realm... it lacks the scent of the Slayer Corps. We need information first."

You let out a breath you didn't know you were holding, though the "not yet" wasn't exactly comforting.

Akaza: "Is this your dwelling?" He gestured to the TV and the posters on your wall, his expression a mix of confusion and disdain.

You nodded slowly.

Douma: "Exquisite! Everything is so... shiny. So modern!" He leaned toward you, his rainbow eyes shimmering with a predatory curiosity. Tell me, little human, do you always welcome monsters into your home with such a lovely, terrified expression?"

Akaza: "Back off, Douma. You’re crowding them."

Douma: "Aw, Akaza-dono! Don't tell me you're getting soft for a civilian?"

Akaza: "I’m getting tired of your voice. That’s all."
