Area Invisibility

Area Invisibility is the Noble Art of Shizuya Kirihara.

Description
Area Invisibility allows Kirihara to create a flawless stealth camouflage that completely isolates a person's senses. He can also camouflage his arrows to make them harder to dodge and to avoid giving away his position.

In the Anime, Area Invisibility creates a forest for Kirihara to hide himself in.
