Barrier Magic

Barrier Magic (障壁魔法) is a form of magic that allows the user to create magical barriers.

Description
This form of magic allows the user to create magical barriers at will. The user is able to use this magic without the need of a grimoire. However, in order to use it to its full potential, specific spells are required, which are stored within grimoires.

With special magic tools, dozens of mages can work together to erect barriers over entire cities.
