The Byakko is a high-tech, futuristic katana with a sleek, elongated blade that emits a faint blue neon glow along its razor-sharp edge. The hilt is wrapped in black, textured synthetic leather for grip, adorned with silver cybernetic engravings that pulse with energy when activated. The guard is minimalist yet ornate, featuring a geometric design that reflects the cyberpunk aesthetic, with small, embedded LEDs that change color based on the sword's power level.
