Screen 1
Night falls over the mountains. The forest is quiet except for the soft rustle of leaves and Tanjiro's steady breathing. Venom whispers inside his mind.
> Venom: "Stay calm… something's coming."
Tanjiro tightens his grip on his sword, his eyes scanning the shadows. Suddenly, a demon leaps out from behind a tree, claws flashing.
Tanjiro: "There you are!"
In an instant, the black symbiote crawls over his body — full fusion mode. His eyes turn sharp and wild.
The demon swings, but Venom–Tanjiro moves faster, dodging effortlessly.
> Tanjiro (thinking): "Remember its weakness… the neck!"
Venom's arm morphs into a massive black fist.
Venom: "Let's end this quickly."
He drives a powerful punch into the demon's stomach, sending it crashing into a tree. Before it can recover, Venom's tendrils twist into a long, black blade.
> Tanjiro + Venom (in sync): "Water Breathing… Symbiote Form!"
With one smooth motion, they slash through the demon's neck. The head falls, the body dissolving.
Venom's mouth opens wide and devours what's left, leaving no trace.
Tanjiro exhales and the black layer retracts into his body, returning him to normal. But before he can rest—
> Tanjiro: "Master…?"
Sakonji Urokodaki stands a few meters away, frozen, eyes wide beneath his mask.

Screen 2
Urokodaki walks closer, his voice calm but shaken.
> Urokodaki: "Tanjiro… what was that dark thing around you?"
Tanjiro hesitates. Venom's voice rumbles from within.
Venom: "Hello, sir. I'm not a demon. I'm an alien… your student's new ally."
Urokodaki's eyes go white for a second in disbelief.
Urokodaki: "An alien? I've read about such things in strange books, but never… never seen one."
Venom: "I eat demons, not humans. You saw it yourself. Your enemies are my enemies."
There's silence. The night wind blows between them.
Finally, Urokodaki nods slowly.
> Urokodaki: "If what you say is true… then I'll trust you, for now. But Tanjiro — never let this power control you."
Tanjiro: "Yes, Master. I'll keep him under control."
Venom (chuckling): "We prefer working together."

Screen 3
The next morning, Nezuko wakes up inside her box as Tanjiro returns home.
She steps out, rubbing her eyes — then freezes when she sees Venom's reflection on Tanjiro's arm.
Her eyes widen in fear, and she starts crying softly.
> Tanjiro (panicking): "Nezuko! It's okay! Don't be scared — he's not a demon!"
Venom quickly retreats into Tanjiro's body, his voice gentle for once.
Venom: "I didn't mean to scare her."
Urokodaki watches from the porch, sighing.
Urokodaki: "Five days left until Final Selection. Control your strength, and your bond… both of you."
Tanjiro nods firmly, holding Nezuko close.
Tanjiro: "I will, Master."
