In the early days of man, some humans were capable of performing miracles, seeing beings known as Faeries and live for an exceptionally long time compared to that of normal humans. The techniques and knowledge that these individuals possessed and shared with one another came to be known as "Magic", and those who wield it was to be called "Mages" by their fellow humans.
But with time, few people are born with the ability to perform Magic; and due to the last "Great War", many magical users such as the Mages and Alchemists died. It has since become unusual, but not rare, to find young people with magical abilities and it's why many of them turn to abduction or slavery to obtain one.
Magic is the result of either using the energy inside one's body, which can be generated or absorbed through sleep and food, or by borrowing power from Faeries, Spirits, and Demons in order to interfere, or outright break, the world's natural laws in order to get the results they want; this is a process that is sometimes called a miracle. While these magical users can access the world's natural laws with the help of magical beings and through sheer force of will, it's easier to perform with the help of chants and wands.
Magic is used by the likes of Mages to get the results that they want, these results vary in shape, form and the requirements to cast them. It can be used for supplementary use such as teleportation, flight, purification and giving life to inanimate objects. It can also be used for offensive purposes such as summoning forth spikes made out of shadows and breathing fire. Magic is also used when creating objects such as rings, which is commonly the work of an Artificer such as Angelica, or wands.
The sight, or the eyes, is the ability to see neighbors. Sight is a separate gift from the ability to use magic.
The Neighbor's goodwill does not always result in the happiness of the human. Sleigh Beggy, who passively absorb magical energy, are often born without sight and do not realize their own power. When left to their own interpretation, the Neighbor's love and loyalty manifests into both luck and ill fortune. 
- Sleigh Beggy (スレイ・ベガ Surei bega): is the rarest among the different types of magical users, even to the point of them being nearly unheard of in this day and age . They have the abilities of both a Mage and an Alchemist. The main characteristic of a Sleigh Beggy is that they passively absorb and generate almost unlimited magical energy. However, their bodies are no stronger than any other mage and will eventually buckle under the constant strain and their will cease to function .
- Mage (魔法使い Mahōtsukai, lit, Magician): is a magical user that absorbs ambient magic from their surroundings to cast spells or by borrowing it from Faeries, however, the former being very draining for the caster.
- Alchemist (錬金術師 Renkinjutsushi): is different from the other magical users as they turn their own physical energy into magic to perform something known as Alchemy. Unlike Mages, they don't interfere with Natural Laws by breaking them, but instead they study these laws and learn to manipulate them.
- Witch (魔法使 Mahōtsukai, lit, Witchcraft): is a magical user very similar to that of a Mage, but the differences being that they often delve into more forbidden arts, such as Curses, and choose to gather in groups known as covens.
