Majos are blind creatures. However, they can "see" inner energy that flow through multiple sensory organs on their heads.
Majos patrol their territories and hunt for preys. Their sensors can pick up slim energy signals from preys even when they take cover or burrow.
Glowing sensors mean that the Majo is picking up signals.
It's assumed that Majos' visions resemble acupuncture charts.
