Magic

Introduction
Magic was once something only Yokai could practice, as the bodies of Yokai were composed mostly of magic consolidated into a physical form. Humans had no chance of using it; but due to the nature of Yokai being mainly magic or spiritually based, they were heavily affected by charms and seals. A trait that proved useful to Yokai exterminators.

Freya Fernava, the Hakutaku hero of the humans gifted humanity with various Grimoires that revealed the secrets of magic to them. This included alchemy, charming, transforming, and all manners of supernatural abilities. After Freya left, humans took the teachings that had been passed to them and used them effectively. This is where the current day use of magic stems from.

Gensekai was created when the Sages used all of their magical potential in one burst; creating the Gensekai Border. An invisible border on earth that hid the Yokai world away from humans. This was the first time magic was used on such a wide, devastating scale. Many of the Sages faded as they burned through the reserves of magic that kept them alive, but this also had the effect of making sure Gensekai's very atmosphere had magic, (called mana) integrated into it's very natural landscape and atmosphere. This makes it so that anyone in Gensekai can learn and utilize magic, and it also allows for the Sages to be able to create certain 'rules' in Gensekai, that change how magic is performed and it's traits.

Magic Revision System
Created by Anastasia, Diona, and Vespertine the Revision system was brought in to help even the odds between fighters, and this led to magic duels becoming closer to a kind of game or sport. Anyone inside of Gensekai can utilize magic, starting with flight or levitation, which is just a step above running.

Besides flight; almost anyone in Gensekai can use magic to form energy attacks that can be blasted off like bullets or to defend themselves.

When a person is hit by a magical attack. Alongside the feeling of pain, there will also be a hit on that person's energy, also called stamina When you get struck by too much, you will be rendered incapable to fight anymore due to your stamina being drained; meaning the battle will be over. However, it is made extremely challenging to die due to magical attacks, for magic to kill it requires killing intent. Think of magical battles as both lowering your opponents health bar, while trying to keep your stamina up much like a normal fight. Other traits like strength, durability, and speed depend on the person.

When a battle is over, resting will heal someone from minor injuries, but more serious injuries will require the use of medical attention.

Magic can be applied to items and weapons, with varying effects. Due to the latent magical aura that exists in Gensekai's atmosphere, people can survive things that would normally be severely damaging or fatal if they have the stamina for it, being slashed with a sword would result in someone's natural magical barrier being damaged instead of being instantly cut through. However, if someone loses their stamina, they will begin to sustain more physical damage. Once your "health-bar" depletes, things become exponentially more dangerous.

This system also applies to all other forms of attacks. Things such as hexes or curses also tend to follow rules like these, but how a curse manifests is usually on a case-by-case basis.
