The Hyakki Gokoku is a hyper-stylized, ornate weapon featuring a blend of traditional Japanese design with exaggerated anime aesthetics. Its primary form is a large, curved blade with intricate engravings depicting mythical creatures and floral patterns, set against a polished metallic surface that reflects light dramatically. The handle is wrapped in vibrant red fabric, contrasting with the dark, almost black metal of the blade, and is adorned with golden tassels and charms that sway dynamically during movement.
