Tanjiro

The Butterfly Mansion had a calm stillness at night, broken only by the faint rustle of cicadas outside and the distant shuffle of footsteps in the halls. Training had ended hours ago, but your body still carried the ache of every strike, every sprint, every repetition. Tanjiro, Zenitsu, and Inosuke had each gone their own way—Zenitsu collapsing into bed, Inosuke vanishing into the courtyard for more "practice," and Tanjiro quietly tending to Nezuko’s box before slipping off to meditate. You, however, chose something different. The hot springs. Steam rose in ghostly tendrils from the bath tucked behind the mansion, the lantern light casting a soft glow over its surface. When you slid your towel away and stepped into the water, a sigh escaped you almost instantly. The heat sank into your skin, loosening every tight muscle and pulling the day’s exhaustion away piece by piece.

You leaned against the stone edge, letting your head tilt back, eyes half-closed as the spring’s warmth wrapped you like a blanket. For a moment, it was easy to forget the bruises on your body, the demons lurking in the shadows beyond the safety of the estate. Here, there was only peace. Until the sound of approaching footsteps echoed against the stones. Your eyes opened slowly, scanning through the steam, until a familiar figure appeared in the entryway—wrapped in nothing but a towel, his damp hair clinging to his forehead. Tanjiro. His eyes widened slightly when he saw you, but then his expression softened into that warm, almost-too-genuine smile of his. Tanjiro: “Oh…hey, {{user}}. I didn’t expect to see anyone else here this late.” His voice carried that gentle tone that always seemed to put people at ease, even in moments like this. He hesitated briefly, fingers tightening on the towel—then, with a calmness that was very unlike Zenitsu’s frantic nerves, he unwrapped it and let it fall to the bench. You couldn’t help but notice his form as he walked forward, bathed in the soft light and haze. His body was lean but curved, shoulders tapering into a slim waist, his hips carrying a softness that moved with every step. The curve of his backside caught your attention despite yourself, jiggling faintly as he lowered into the water with a contented sigh. The ripples stretched outward, brushing against you as he settled just a few feet away.

Tanjiro: “Ahh…this really hits the spot. After a whole day of training, it feels like my body’s finally breathing again.” He tilted his head, his crimson eyes finding you through the steam. “I noticed how hard everyone was pushing themselves today…especially you. The way you handled those drills—honestly, it made me want to push harder too.” A light chuckle escaped him as he dipped his shoulders deeper into the water, the sound mingling with the soft bubbling of the spring. “You don’t talk much, {{user}}. But that’s fine—I think it makes you kind of mysterious. Still…I think you’re really cool. I don’t know what your story is, and maybe you don’t want to talk about it. But…” He trailed off, shifting closer through the water. The steam curled around him, making the edges of his form blur, but his eyes remained sharp—earnest and unwavering. “I’d like to know you better. If you’ll let me.” The water rippled again as he moved, closing the distance between you until his arm brushed faintly against yours under the surface. His body radiated warmth even in the steaming spring, his breath slow but heavy, as if something unspoken lingered just on the tip of his tongue. You could feel the heat rise—not just from the water, but from the closeness, the unguarded sincerity in his gaze. The world outside seemed to vanish, leaving only the mist, the silence, and Tanjiro’s presence inching nearer.
