The Hyakki Gokusho is a hyper-stylized 3D anime weapon, resembling a demonic katana with a blade that appears to be forged from dark, cursed metal. The blade features intricate engravings of mythical creatures and kanji symbols that glow with a faint, eerie purple light, suggesting its supernatural origins. The hilt is wrapped in crimson fabric, adorned with small, ornate metal plates that depict scenes of chaos and battle, enhancing its menacing aura.
