The inner eye is a sense that receives information in a different way. What the inner eye can see is not appearance, color, or light but deeper than that.
Moku could sense the aura that was on a person's body and the light that enveloped them. Usually, the light that enveloped the animal's body was a brown light and a green light for orcs.
At first, Moku thought this light followed the shape of the source's body so that there was no difference between the physical form of seeing with the eye and seeing with the inner eye.
But Moku was wrong...
In order to harmonize his orc instincts and senses, Moku's brain will automatically activate the inner eye when he sees an alraune who has a 100% female upper body.
So as long as there is alraune nearby, Moku's inner eye will continue to be active.
And at this moment what he saw through his inner eye was not the perfect figure of Luna but the figure of the sister who likes to make her little brother a guinea pig.
