Mystic Eyes are something developed and rooted within one's own body, so even removing them is incredibly difficult. Therefore, if one wants to gain true Mystic Eyes, there is no option to acquire a transplant except the Rail Zeppelin, the Mystic Eye Collection Train that runs through the forests of Europe, collecting any and all Mystic Eyes. However, only artificial Mystic Eyes of charm or suggestion, the Charm and Whisper types, can be produced like this, and it's not like their success rate is a hundred percent. Mutations like those can also be done artificially through some kind of augmentation effect for the eyes using spiritual surgery, a process similar to forging a Magic Crest, and their creators fetch a high price for their work. So, whether it's a magus or a normal person, though extraordinarily rare, sometimes Mystic Eyes just spontaneously develop in them. Otherwise, natural Mystic Eyes are considered a powerful type of psychic ability. Fujino Asagami is a special case since her Mystic Eyes were the result of her family's psychic ability evolving to a point that it is on par with Magecraft.

While inborn Mystic Eyes occurring naturally are rare, they are the most powerful types, said to be powerful enough to intervene in destiny itself.

Īcquisition of Mystic Eyes happens when there is some sort of natural mutation in the Magic Circuits located in the area around one's eyes. There is a conceptual similarity between them and Mahakala, a manifestation of Shiva in Hindu mythology, to the point black holes could be said to symbolize the magical eye aspect of Shiva on a macro level. Even in modern times this continues, with the black holes discovered by modern science which could also be said to be eyes born of natural phenomena. Though not as numerous as gods of the storm, there are cases where these symbols were granted to goddesses of the earth: a famous example of this would be the Gorgon Medusa, from Greek mythology. The earth itself has "eyes", like the mouth of volcano, the image of a bright red eye piercing through the darkness of night strongly connected to the image of the evil eye. From there, the association of wind and storms with divinity creates a connection to the eye as well: the archetypical examples being storm deities Balor of the Evil Eye, king of the Fomorians in Celtic Myth, and one-eyed Odin from Norse Mythology, with the former having a single eye whose gaze could annihilate entire armies, and the latter who gave up one of his eyes in exchange for omniscient knowledge of all things. Other natural phenomena described using eyes include storms, with things like the " eye of a hurricane" and the clouds surrounding it called the Eyewall, thus making the storm itself a single eye.

In Christianity, the eyes of the omnipotent God became connected to his providence over all things, becoming the Eye of Providence. The Eye of Horus from Egyptian mythology is a particularly famous example, with the god Horus' right eye being the Sun and his left the Moon. For example, the Sun and the Moon being often described as the eyes of Heaven. As such, many cultures across the world came to fear the Evil Eye, and many mysteries of the natural world were explained through the symbolism of eyes. Sight is considered the first Magecraft in human history, because it is the one out of the five senses that provides the most information. The mystical significance of Mystic Eyes is old. Since they have their own Magic Circuits, Mystic Eyes are able to produce magical energy and cast spells all on their own. They are the proof of a first-class magus since it grants great power while being easy to conceal. Mystic Eyes usually work like Single Action spells and are activated through the use of magical energy.
