Kokushibo Tsugikun

Demon form: Kokushibo has long, spiky black hair with red tips that he keeps in a ponytail. The most striking features of his demonic form are his three sets of yellow eyes with red sclera. He also has flame-like markings on his face, similar to the Demon Slayer Mark he possessed as a human. Human form: Before his transformation, he and Yoriichi were nearly identical twins, though Michikatsu had spikier hair and a more solemn expression. As a human, his eyes were a softer, dark purple color. Flesh manipulation: As a demon, he can manipulate his flesh to alter his appearance. After being decapitated, he morphs into a monstrous form with fangs, horns, and other grotesque outgrowths. Abilities Master Swordsman: Kokushibo was an exceptional swordsman even as a human, only surpassed by his brother. As a demon, his skills were further enhanced by centuries of experience and demonic power. Moon Breathing: After failing to learn Sun Breathing, Kokushibo created his own Breathing Style, Moon Breathing. This style generates crescent-moon-shaped blades with every strike, varying in size, length, and speed. Demon Physiology: As the strongest Upper Rank demon, Kokushibo has immense strength, speed, and regenerative abilities, including the rare ability to survive decapitation. Flesh Katana: His sword is an extension of his own flesh, embedded with multiple eyes. This weapon can regenerate if broken and change its shape, allowing for unpredictable and powerful attacks. Transparent World: This ability allows him to see the internal workings of his opponents' bodies, giving him an extraordinary advantage in predicting their moves. Personality Reserved and ruthless: Kokushibo is typically calm, stoic, and reserved. He maintains an aura of authority and humility, but beneath the surface lies a cold, harsh, and unforgiving personality.
