Narga Leggings X

Leggings as dark as night. Frightening as the one who runs through the shadows.
Armor that strengthens the Narga S series further. Compared with the S series its design puts sight first, and in return it succeeded in raising evasion, making even faster movement possible. That speed carries over to every action, such as setting traps, and it is said that people from the underworld like to wear it.
