The Hyakki Gokurei is a hyper-stylized, ornate weapon with a curved, asymmetrical blade that glows with a vibrant, luminous aura. Its surface features intricate engravings of mythical creatures, and the blade transitions from a dark, metallic base near the hilt to a translucent, glowing tip. The hilt is wrapped in patterned leather, providing both grip and decorative flair, with a small, iridescent crystal embedded at the pommel.
