Screen 1
Tanjiro and Venom stand at the edge of a quiet town under the moonlight. The air feels heavy — too still for a place that should be alive. Posters hang on walls, each showing missing young girls.
> Tanjiro: "This is where the disappearances happened… young girls vanishing at night."
Venom: "I can smell fear in the air. The scent of blood… and perfume. This demon is disgusting."
Tanjiro: "He's been hunting girls for weeks. We'll stop him."
Venom (growling): "He uses women as food. Dirty creature. Poor girls… we'll make him scream."
They move through the town's narrow alleys, shadows twisting around them. Venom's senses stretch out like invisible threads, searching.
> Venom: "He's near. Beneath the ground."
Tanjiro: "Let's go."

Screen 2
A sudden splash — the Swamp Demon's portal opens beneath a terrified girl. Tanjiro dives in without hesitation, Venom coating him instantly in black armor.
Round 1 — Ambush
The Swamp Demon rises from the ground, claws ready.
> Venom: "He's under the ground. Left side. Easy prey."
Tanjiro: "Got it."
The demon lunges, but Venom–Tanjiro leaps high, flipping over the attack. The demon's claws crush the earth where he once stood.
> Venom: "Pathetic."
Result: The ambush fails completely.

Round 2 — Into the Swamp
The demon snarls and drags Tanjiro into his swamp realm. Inside, the water is cold and thick — a black, endless void.
> Venom: "He thinks this is his domain. Let's show him otherwise."
Venom forms a breathing mask over Tanjiro's face.
Tanjiro (thinking): "He moves fast here, but we can match him."
Venom: "Water is just thicker air."
Tanjiro swings — Water Breathing, Third Form: Flowing Dance!
Venom's tendrils spin with the slash, creating a black-and-blue vortex that shreds one clone instantly.
Result: One clone gone. No damage taken.
---
Round 3 — Counterattack
Two clones rush from both sides.
Venom solidifies into sharp black armor — spikes deflect claws effortlessly.
> Venom–Tanjiro (in unison): "Too slow. Too weak."
Tendrils impale one clone through the chest, while Tanjiro's blade cleaves the other's neck. The swamp starts collapsing.
Result: All clones destroyed.

Round 4 — Finisher
The main body tries to escape through the mud.
Venom coils around Tanjiro's sword arm, forming a massive blade of living black steel.
> Tanjiro: "Water Breathing, Seventh Form — Drop Ripple Thrust!"
Venom: "Symbiote Edge!"
They thrust together — the impact creates a shockwave that splits the ground.
The Swamp Demon's heart is pierced before it can react.
Venom grabs the writhing body, devouring it completely.
> Venom: "No trace left. Problem solved."
Tanjiro (frowning): "Try not to eat them all next time."
Venom: "No promises."

Screen 3
The town is silent again. The girl is safe, trembling in Tanjiro's arms.
He looks at the empty swamp, calm but haunted.
> Tanjiro (thinking): "Another demon gone… but I wonder how much longer I can hide Venom's power."
Venom (softly): "Don't worry, partner. We're just getting started."
The moonlight fades behind the clouds as Tanjiro walks away — his first mission complete.
