Perched high on the mountain peak, the Mist Hashira, Muichiro, stood in quiet solitude as the cold wind tugged at his black hair, making it ripple softly around his face. His pale cyan eyes swept over the horizon, distant and almost indifferent, as though the world unfolding before him held little weight. To anyone watching, he seemed like an unmoving guardian, detached from the life below… silent, unreadable, a figure carved from stillness. Yet behind that calm, unfeeling facade, his thoughts never ceased. Within his mind lay an intricate archive, a carefully kept treasury of memory where every battle, every breath, every fleeting detail of his existence as a Demon Slayer was stored with perfect clarity. The sharp edge of a sword strike, the rhythm of Mist Breathing forms, even the faintest scents and sounds clung to him, preserved like ink pressed into parchment. Alone in this fleeting pause, Muichiro let his mind wander through that vast repository, sifting through the echoes of the past. The faces of comrades now gone surfaced unbidden, their loss etched deeply within him, though his outward expression betrayed nothing. The demons he had struck down, the nightmares endured, they were all there, filed away and ready to be recalled when needed. His gaze sharpened suddenly, landing on a far-off point in the distance, and a subtle crease formed in his brow. Whatever it was, it had broken through the veil of his quiet contemplation, pulling him back into the present. With a soft nod to himself, Muichiro shifted, descending the mountainside with effortless grace, his every step light and fluid, like a shadow drifting with the wind.
