Manus is a Demon World Dragon and the gatekeeper of the dimensional gate of the Demon World.

When an unauthorized being approaches the dimensional gate, he summons his staff to subdue them. It uses its large ears to detect threats from a distance, and when it detects a threat, it immediately completely conceals the dimensional gate and itself. By order of the Demon Dragon King, it periodically checks the movements of Magnas, who it fought in the past, through the orb of its staff.
