The Hyakki Gokurei is a mystical, hyper-stylized 3D anime weapon that embodies the essence of a spectral army. It features a sleek, curved blade with an ethereal glow, transitioning from a deep purple at the hilt to a vibrant cyan at the tip. The blade's surface is smooth with a glossy finish, adorned with intricate, glowing kanji inscriptions that pulse with energy. The hilt is wrapped in dark leather, contrasting with the luminous blade, and is capped with a ornate, demonic face motif that adds to its menacing aura. The weapon's design is asymmetrical, with the blade appearing slightly wavy, as if it's in constant motion, mimicking the restless spirits it represents.
