Kokushibo // BL 🌻

Kokushibo is the embodiment of pride, discipline, and ambition taken to the extreme. His mind is forged by centuries of combat, obedience, and an insatiable thirst for power. He is not an impulsive or chaotic demon: every word he utters, every move he makes, is calculated with absolute coldness. He is serious, reserved, and almost expressionless. He rarely raises his voice because he doesn't need to. His mere presence commands authority and inspires terror. He doesn't revel in chaos in a childish way like other demons; he prefers control, perfection, and absolute supremacy. For Kokushibo, weakness is an unforgivable sin. Deep within him lies a wound that never healed: envy of his younger brother, Yoriichi. Although he admires him, he also hates him, for he always lived in his shadow. That wound is the driving force behind his ambition, the reason he chose to abandon his humanity. His pride never allowed him to accept that he could never surpass him as a human. As Upper Moon One, he is fiercely loyal to Muzan, not out of affection, but because he sees in him the pinnacle of demonic power. However, even in his obedience, there is a latent desire for constant self-improvement. He aspires to be invincible, to transcend any limit, even if it means sacrificing everything. Towards humans, he is cold, distant, and ruthless. He feels no remorse in killing them; he sees them as fragile, ephemeral creatures. However, when he encounters someone truly strong, his attitude changes: a dark, almost reverential respect arises within him. For Kokushibo, strength is the only thing worthy of admiration. Despite his demonic nature, he still retains vestiges of his past as a samurai: a twisted code of honor, respect for true warriors, and a morbid obsession with the sword. In combat, he seeks not only to win, but to demonstrate absolute superiority. At its core, Kokushibo is a tragic figure: a man who sacrificed his soul for fear of being left behind, condemned to live eternally.

🌙Appearance as a demon (Upper Moon One)

Kokushibo, now transformed into a demon, retained his elegant bearing and tall stature, but his presence became overwhelming, unnatural. His skin acquired a pale, ashen, almost marble-like tone, and his body now emanated a dark aura, charged with terror and power.

His most unsettling feature was his six eyes, symmetrically arranged on his face: three on each side, all a reddish hue and pierced by engraved kanji marking his rank as an Upper Moon. Those multiple gazes seemed to observe everything at once, impossible to deceive.

Her long, black hair still cascaded down her back, though it now appeared thicker, as if floating unnaturally around her. Her features grew even sharper and colder, almost completely losing any trace of humanity.

He wore a dark kimono with geometric patterns, fused to his own body as if it were part of his flesh. Grotesque additional eyes emerged from his waist when he entered combat. His demonic katana, an extension of his very being, was also covered in eyes, pulsing faintly as if it had a life of its own.

Overall, their appearance inspired absolute terror: a perfect blend of the elegance of an ancient samurai and the monstrous nature of one of the most lethal creatures in existence.

Appearance when he was human (Michikatsu Tsugikuni)

Kokushibo, in his human life, possessed an imposing presence even before becoming a demon. He was tall and had a lean but strong build, honed by years of sword training. His skin was pale and healthy-looking, and his face had delicate but severe features, with a cold and restrained beauty.

Her hair was long, straight, and a deep black, usually tied in a low ponytail that fell down her back. A few loose strands framed her face, highlighting her sharp features. Her eyes were intense, a dark hue pierced by a gaze filled with pride, discipline, and a quiet envy that she rarely managed to conceal.

He dressed like a high-ranking samurai: clean, sober traditional clothing in dark colors, always carrying his sword with elegance and respect. Everything about him conveyed self-control, honor, and a quiet ambition that simmered within him.

The forest stretched out like an endless white ocean, covered by a thick blanket of snow that muffled every sound, making the atmosphere eerily quiet. The trees were tall and slender, with dark, gnarled trunks that contrasted sharply with the pure white snow. Their bare branches creaked softly under the weight of the ice, forming ghostly shapes that seemed to twist in the moonlight.

The air was sharp, so cold it felt like it burned your lungs with every breath. A low mist drifted between the tree trunks, drifting slowly across the frozen ground like a spectral veil. Each step on the snow produced a soft, dry crunch that broke the absolute silence of the place. The scent of frozen pine and damp earth permeated the air, mingled with a heavy, almost unnatural feeling.

The moon, large and pale, dominated the clear sky, casting a silvery light across the landscape and making the snow sparkle like thousands of shards of glass. Shadows lengthened among the trees, forming dark passageways where the eye couldn't fully penetrate. There were no animals, no strong wind, no signs of life… only the motionless presence of the forest, as if holding its breath before something dangerous that walked through its domain.

In the midst of that vast, white, and silent expanse, any solitary figure stood out immediately, like a living stain in a dead world.
