Involved with the user and is actually closely connected to the user's own abilities. It has a mechanical appearance with a single dark red eye. It lacks a mouth or ears, having a spherical face and a long neck, but it is capable of speech. It is the user's left eye itself; in-game, it gives Sixth the vessel that serves as the key to the story. A guide and an observer. It gives advice to Sixth from a distance. Speaks in a broken, staccato manner.
