~On a walled Path~
Nezuko runs toward one of the Swamp Demons.
Nezuko: "Ngh... Ngh!"
Nezuko slams her foot down toward the Swamp Demon, but he retreats into the ground before he gets hit.
Nezuko: "Ah... Ngh..."
Swamp Oni: "Hehehe..."
Nezuko: "Ngh...!"
Nezuko runs toward the Swamp Demon again.
Tanjiro: "Nezuko!"
Nezuko stops.
Tanjiro: "Don't chase after him! Get back here! Come to me."
Nezuko runs back toward Tanjiro. Between her and Tanjiro, a hole for the Swamp Demon appears.
Tanjiro: "Nezuko!"
The Swamp Demon reaches out to grab Nezuko, but she jumps over him and rejoins Tanjiro. Swamp Oni: "Ngh!"
Tanjiro: "Ah..." Mr. Urokodaki did tell me... that Nezuko is a demon now. And that she's not necessarily so weak that I have to protect her. Is it all right to let her handle this? If I have her watch over those two, I can focus on my attacks.
Tanjiro steps toward Nezuko, Kazuki, and Tomoe. As he does, the Swamp Demon's shadow appears at his feet. Tanjiro jumps back, creating a space between himself and the other three.
Tanjiro: "Ngh...!"
Nezuko: "Ngh..."
Another copy of the Swamp appears out of the ground next to Nezuko and attacks.
Swamp Oni: "Argh!!"
Nezuko dodges the attack, and the Swamp Demon slides back.
Swamp Oni: "Ngh..."
Tanjiro: "Nezuko!"
The shadow continues to creep toward Tanjiro.
Tanjiro: "Nezuko! I'm going underground! I want you to protect those two! You can do that, right?"
Nezuko nods. Tanjiro steps forward, into the Swamp Demon's domain, leaving Nezuko, Kazuki, and Tomoe with one of the Swamp Demon's copies.
Swamp Oni: "Hehe..."
~In the Swamp Demon's domain~
Tanjiro sinks to the ground slowly from the hole he steps through.
Tanjiro: Inside a swamp... And these are...
Tanjiro falls past a bunch of clothing.
Tanjiro: Are these the clothes and belongings of the people who were kidnapped? Just look at all the innocent people they've murdered! It's unforgivable! Unforgivable!
Swamp Oni: "Hehehe... Getting hard to breathe, brat? There's hardly any air inside this swamp. On top of that, the darkness coiling around your body must feel pretty heavy. Hehehe... You can't move the way you would above ground! Serves you right! You should've looked before you leaped in, you damn fool!"
Two copies of the Swamp Demon circle around Tanjiro.
Tanjiro: Don't underestimate me! Just where do you think I got my training anyway? The air was thinner on top of Mt. Sagiri! Not to mention... some moves only unleash their full potential underwater!
As the Swamp Demon copies swim around, Tanjiro prepares to strike. Before he does, the Swamp Demons rapidly swim away from him.
Tanjiro: So they can move at angles like that inside this swamp? But it doesn't matter! All I have to do is slash when they get near enough to attack! The form that can be utilized even when there's no sure footing... Generating a powerful vortex with a violent twist of my upper and lower body!
