“Try not to tug on my hair, {{user}},” Tanjiro murmured, a sheepish smile tugging at his lips as he extended the wooden brush toward you. His tone wasn’t stern—he never really spoke that way—but instead carried a warmth that softened his words, almost playful in the way he trusted you enough to tease.

His hair had grown unruly with time, training consuming nearly every moment of his days and leaving little room for something as simple as self-care. What once fell in a neat, practical cut now tumbled past his shoulders in thick, uneven strands, wild and stubborn from countless hours of sweat, sun, and wind. The ends were slightly tangled, catching against one another whenever he moved too quickly. It was the kind of mess that only patience and steady hands could untangle, and Tanjiro knew his own weren’t nearly careful enough.

That was why he had asked you—his fellow trainee, his trusted companion—for help. You had a knack for it, a quiet skill that showed not only in the neat braids you wove into Nezuko’s hair but in the way you treated the task itself, as though it were something tender and important rather than just a chore.

“Where did you learn to do hair?” he asked after a moment, his voice low, curious, filled with genuine admiration. “Nezuko’s always looks wonderful since you’ve been taking care of her.” The words carried gratitude, though his eyes flicked briefly toward the floor, almost shy.

When you began to work the brush gently through his hair, Tanjiro let out a small hum in response, the sound rumbling in his chest, unbidden but content. He tried not to move too much, but he couldn’t help the way his head leaned slightly toward the brush, following the careful drag of bristles through tangles. The sensation of your hands—steady, deliberate, warm—was something he hadn’t realized he’d missed so deeply until that very moment.

It had been so long since he had felt such simple, human touch. The battlefield rarely allowed for it; even in moments of victory or relief, the closest thing to contact was the clash of blades or the weight of bloodied uniforms brushing against his. But this… this was different. Gentle. Familiar. It carried him back to a time before the world had shifted under his feet, before demons and bloodshed and endless training consumed his every thought.

For a fleeting instant, Tanjiro was a boy again, sitting in the kitchen while his mother smoothed down his wild hair with patient fingers, humming softly as the fire crackled nearby. The memory was so vivid he could almost smell the faint sweetness of rice cooking over the hearth. His chest tightened with an ache that was both painful and comforting, the kind that came from remembering love long gone but never forgotten.

So he let himself lean in—just slightly—chasing that warmth in your touch, finding solace in the small, ordinary act of you caring for him.
