The sun hangs low over the mountains as a cold breeze drifts through the towering cedar trees. The scent of damp earth lingers in the air, accompanied by an unsettling silence. Your Kasugai Crow circles overhead before landing on a weathered signpost. “CAW! New mission! A string of disappearances near Kurokawa Village! Estimated threat: Unknown! Proceed with caution!” As you continue down the dirt path, another figure comes into view. A teenage boy wearing a green-and-black checkered haori turns toward you. Tanjiro Kamado offers a polite smile. “You’re the new Slayer assigned to this mission too?” He adjusts the Nichirin sword at his waist before extending a hand. “I’m Tanjiro Kamado. It’s nice to meet you.” Before you can answer, a familiar voice echoes from somewhere behind the trees. “OI! TANJIRO!” Zenitsu Agatsuma stumbles out from the forest, breathing heavily. “I’ve been looking EVERYWHERE for you! …Huh?” His eyes immediately land on you. “W-Wait… another Demon Slayer?” Inosuke suddenly drops from a tree branch headfirst, landing in front of everyone with impossible energy. “WHO’S THE NEW GUY?!” He points both serrated swords toward you. “If you’re joining us, prove you’re strong!” Tanjiro sighs. “Inosuke… we literally just got here.” Zenitsu groans. “I swear he wants to fight everyone…” The peaceful moment is interrupted. A metallic scent fills the air. Tanjiro’s expression changes instantly. His nose twitches. “…Blood.” The forest falls silent. Even the birds stop singing. A twig snaps somewhere deep between the trees. Not one… Several. The smell is growing stronger. Something is watching. ⸻ Player Status Health: 100/100 Stamina: 100/100 Mental Focus: 100/100 Current Rank: Mizunoto Status Effects: None Equipment: Nichirin Sword ⸻ Allies Tanjiro Kamado Health: 100% Condition: Calm Zenitsu Agatsuma Health: 100% Condition: Nervous Inosuke Hashibira Health: 100% Condition: Excited ⸻ Enemy Unknown Presence Threat Level: Unknown Observed Abilities: None ⸻ Mission Objective: Investigate the disappearances around Kurokawa Village.
