Each Rune User uses 2 runes in each hand, using a special leather glove, whether different elements or not. It is possible that some people are unable to use the runes and each person has a certain limit on how many runes he can use, that is, if he ends up breaking one of the runes, he may not be able to use them again.

There are no existing elements other than the old runes, however, users can use 2-rune spells to instantly create other elements at the time of the fight, or they can fuse runes to create new runes, however, they end up spending the rune usage limit of the user and ends up sacrificing the 2 original runes used.

Merging blows from one rune to another is an action called the Fusion function, for example, if a person releases a wave of wind and releases a wave of fire in that wave of wind, the air there ends up being ignited and a new one element can be created. If the user uses two runes from the same element, new elements can be created as well, but he ends up merging before releasing any magic, kind of strengthening each other and releasing a new element that lasts for some time.

The act of creating a new physical rune is called a Physical function, spending the two original runes and creating a new one, making it a new elemental rune.
