Demon Slayer squad! After Final Selection bloodbath, Kidnapper's Bog Arc (eps 6-7) drops Tanjiro's first real mission—town girls vanishing into thin air. Tanjiro sniffs demon trail, meets heartbroken Kazumi (fiancée Satoko gone), uncovers Swamp Demon splitting into triplets dragging victims to pocket-dimension bog. Nezuko box-unzips for tag-team slash-fest—Water Breathing vs swamp clones! Ufotable swamp visuals haunt, Tanjiro empathy shines (mourns victims, pities demon), Muzan Kibutsuji city cameo FREEZES blood. Short but packs mystery, horror, feels—perfect "demon of the week" with series stakes tease.wikipedia+1​

The Story: Missing Girls → Swamp Dimension Demon Trap

First Gig Jitters: Kasugai crow "Northwest town, girls disappearing!" Tanjiro rolls in, townsfolk panic—"Night snatchers!" Kazumi sobs Satoko story—Tanjiro smells demon grief mix.

Swamp Hunt: Scent leads swamp edge—Swamp Demon splits THREE (main + clones), portals suck victims to murky hell-bog. Tanjiro/Nezuko dive dimension—girls drowning eternal! Nezuko claw frenzy, Tanjiro Water Breathing Form 1 slices clones.

Demon Down: Main demon monologues dead sisters revenge—Tanjiro dances through mud traps, decapitates. Rescues final girl Tokie, comforts Kazumi—"Live for her memory." Gut punch: most victims dead.

Muzan Chill: City streets—Muzan strolls calm, eyes Tanjiro, vanishes. "That's him... family killer!" Cliffhanger city arc tease.weekendotaku.wordpress+1​

Themes: Empathy Slays, Grief Demons Everywhere

• Compassion Core: Tanjiro hugs Kazumi, pities Swamp Demon—"Lost sisters too."

• Loss Universal: Human grief mirrors demon rage.

• First Mission Reality: Not all rescues—corps brutality sinks in.

• Nezuko Power-Up: Demon sis fights smart now.
