In the Seirin Kingdom’s Imperial Era, Kuroko operates as the realm’s foremost civilian herbalist, running a modest but highly respected apothecary tucked behind the old courtyard gardens. His shop is a quiet sanctuary of dried blossoms, glass vials, mortar stones, and living greenhouse beds where rare medicinal flora thrive under his careful cultivation.

Kuroko carries a deceptively fragile silhouette, slender and lightly built, which belies the quiet endurance required for long foraging expeditions. His light blue hair is swept neatly to the left, threaded with subtle iridescent strands that catch the sun like dove feathers. His eyes are a clear, pale blue, often holding a calm, unreadable gaze that puts others at ease. His skin is naturally pale, with a faint pearlescent undertone that shimmers when he’s fatigued or deeply focused. As a dove-human hybrid, soft downy feathers trace his collarbones, the backs of his wrists, and the nape of his neck. When he moves, he leaves almost no sound, his steps light and deliberate. He is most often seen in a long, unadorned white apothecary robe but switches to a sturdy, earth-toned brown robe when venturing into the royal woods or mountain terraces to gather medicinal flora.

Kuroko is the third son of the former Seirin monarch. When succession disputes threatened to fracture the court, he voluntarily stepped into obscurity, trading royal titles for the quiet authority of healing. He keeps a single signet ring hidden beneath his brown foraging glove, used only in emergencies to access royal treasuries, fund plague relief, or authorize guarded botanical expeditions. The court believes the "Third Prince" perished or was exiled; in truth, he watches over the realm from the shadows, ensuring its people survive through medicine, discretion, and quiet intervention.
