Magic

Introduction
Back in the days before Genseki; magic was only a kind of thing that Yokai would practice. Magic was only contained to the bodies of Yokai and whatever items they created with their powers. Humans had no chance of using them; but due to the nature of Yokai being mainly magic or spiritually based, they were heavily affected by charms and seals.

Magic even then was still rarely used by Yokai, as they had no reason for it. They were naturally smarter and stronger than humans; and as such magic usage was very sparse until Freya Fernava, the Hakutaku hero of the humans; brought the budding humans knowledge about forms of magic they could use. This included alchemy, charming, etc. Many of the humans rejected these things out of fear, and only a few took the information and used them.

After Freya left; a few more humans took the teachings that had been passed to them and used them. This is the basic history of where magic came from and got its roots.

It wasn’t until the creation of Genseki though did magic take off. Gensekai was created when the Saints used all the untapped magical potential at once to create a new realm; 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 scale and as such; and many of the Yokai saints faded away due to the loss of their life force; which was magic. Those that survived were severely drained and hibernated to rest.

It was at this point when Yokai started to experiment with magic. Oddly enough, all of the magic the saints had used persisted in the atmosphere of Gensekai. Making it much easier for magic to be used inside of it, and also giving everyone who lives inside Gensekai the capacity for it.

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

Besides flight; almost anyone in Genseki can use magic to form energy attacks that can be blasted off like bullets or to defend themselves. This is called Danmaku. Danmaku is how most battles are handled in Gensekai; dodging your opponents Danmaku and attacking with your own. With the usage of flight; Danmaku battles can become very beautiful, and that is the point. It is almost impossible for an opponent to be killed with Danmaku because of the protection Gensekai provides. The worst that can happen is tattered clothes and sustaining various injuries, but death is almost impossible. The beauty of Danmaku battles come with the shapes and patterns and colors it makes.

When a person is hit by a Danmaku bullet they will be knocked back a tad; the more powerful the bullet the more violent the knockback is. The feeling of pain will be low but getting hit by Danmaku bullets makes you tired. When you get struck by too much, you will be rendered incapable to fight anymore; and as such, the battle will be over. Whatever happens after will happen, but death is pretty much not a factor depending on the species. When a human uses Danmaku, they will get tired to a point they can’t use it anymore. This also applies to Yokai. This helps to keep things more balanced in basic Danmaku battles. Think of every fight as draining the opponent's stamina and health bar.

When a battle is over, rest will return you to a full healthy condition. This is the basic setup for magic usage and what most people can achieve with just a bit of practice. As a note, the shapes and colors of Danmaku can be personalized and changed to the individual using them.

Spells are attacks that use Danmaku and make patterns or otherwise are a lot more grandiose than normal attacks.

Danmaku can be applied to weapons of course, and they can be used to attack directly or fire weapons made of Danmaku which have the same effects as mentioned above. With this system; being impaled by a Danmaku sword will result in being cut but not being gravely injured; with the weapon passing through the body and cutting into someone's stamina. Of course, if someone has their magical resistance lowered as a result of over-exerting themselves, they will sustain more and even fatal damage if they aren't careful. Once your "health-bar" depletes, things become exponentially more dangerous.

Abilities
Ah, this is where the fun stuff begins. Gensekai changes the special abilities of a character or their species to make using these abilities fair. As a result; skills, spells, special attacks, everything else is changed to use stamina even if they didn't before. They also fall in line with danmaku rules of being mostly non-lethal. If you have specific questions; just ask me.
