Mage

Mage (魔法使い) refers to an individual who utilizes Magic. The types, methods and quantity of magic that a Mage can use depends on the Mage's specialization, proficiency, body, and available tools.

External Magicule-based Mage
The vast majority of Mages possess too little of their own Magicule reserves to be able to directly cast any Magic. To counteract that problem, they make use of the Magicules in the surroundings and if there are too few Magicules available in the surroundings, or have already been used up, they can utilize Magic Items such as Magic Crystals, that can store Magicules instead.

Internal Magicule-based Mage
Majin as well as some races of demi-humans and other strong individuals have an internal Magicule storage large enough to directly cast spells without needing to use the surrounding Magicules or some other Magicule storage device, making them less dependent on outside sources.
