Developed before Modern Magic, Ancient Magic (古式魔法) is capable of different things, most of it is specialized beyond the capabilities of modern magic. Generally, ancient magic is slower and more focused than modern magic, as practitioners do not use Casting Assistant Device (CAD) and instead use talismans and the like. As well, back in the day, slower invocation speeds were prevalent, so magic sequences were often much more convoluted to prevent easy identification and negation of the spell. Ancient magic and modern magic use the same principle, use interference on data and rewriting the phenomenon, but are expressed in different ways. Families that inherit ancient magics tend to hide their abilities, although in the new age of categorization, it tends to be a little less pronounced. In terms of surprise attacks, ancient magic boasts superior firepower and secrecy.
There are some ancient magics that allow people to fly, which was impossible to replicate with modern magic until Shiba Tatsuya accomplished it.
The devices used for assistance in casting magic by ancient magicians listed below. The modern CAD replaces the need for such things (including even hand signs).

Spirits are an assemblage made of concepts such as wind, fire, earth and water and are different from individual phenomena.

|“||“Parasite is also one of the acknowledged terms. Monsters, evil spirits, djinns, demons, of all the various entities in the different countries, we call the magical beings that infest human beings and turn them into inhuman creatures as parasites. Even if Ancient Magic has become globalized, that still doesn’t change the fact that they keep their secrets to themselves, so it’s not surprising that everyone here with a modern magic background doesn’t know about it.”||”|

|“||“Spectral form refers to the information body that is shaped like the physical body, except that it links the physical flesh with your spirit. The key to the spectral form is life, or life force. Monsters that devour the flesh and blood of man are rumored to prey on the life force that is taken with the flesh. Vampires drink blood and ghouls consume flesh, but since they weren’t material beings in the first place, they should only be interested in life force. At least, if what the elders in Ancient Magic told me is to be believed. The spectral form and the physical body possess the same shape. Since the capacity size is a given, the original amount of life force compared to the current level is more or less detectable.”||”|

Although it does not have the gift of sight, the atmosphere of what the corpse sees can be passed on to the spell's master. Ancient Magicians from the mainland try not to have anything to do with this spell, although it is used by Zhou Gongjin's master in Volume 12.
