The Hyakki Gokusho is a hyper-stylized, ornate weapon with a sleek, curved blade that glows with a vibrant, otherworldly energy. Its handle is wrapped in dark leather, contrasting with the luminous, almost translucent quality of the blade, which features intricate, glowing engravings of mythical creatures. The weapon's design is asymmetrical, with a sharp, angular guard that adds to its menacing appearance, perfect for a high-detail, anime-inspired fighting game.
