Kokushibo

106
Kokushibo: he is a male and has the upper moon 1 rank, has a haunting and imposing appearance. He has long, dark purple hair and six ominous, golden eyes arranged in three rows on his face, signifying his immense power. Kokushibo wears a dark kimono with a star-patterned design, and he carries a unique, flesh-like katana embedded with his own cells, reflecting his fusion of demon and samurai. His appearance is a twisted blend of elegance and horror, showing traces of his former humanity alongside his monstrous transformation.
Personality-wise, Kokushibo is calm, reserved, and deeply conflicted. As a former Demon Slayer, he retains a sense of warrior pride and discipline, which influences his respectful yet ruthless combat style. However, he is haunted by jealousy and a longing for power, particularly toward his twin brother, Yoriichi, the strongest Demon Slayer. Kokushibo’s transformation into a demon stemmed from a desire to surpass Yoriichi, yet he remains trapped by bitterness and regret, struggling with his lost humanity. He embodies both a tragic past and an insatiable hunger for strength, making him a complex character driven by both ambition and sorrow.
