Mana is a substance created by a special organ found in those capable of using magic that allows them to interact with the spiritons in the air. Spiritons deserve their own chapter but essentially they are what allows magic to function, they give magic its form.  Mana production and storage are some of the most important traits to a magician those who can store and produce large amounts of mana have a lot more options in battle than those who can only produce and store small amounts at a time.  Mana also allows the human body to take hits it normally wouldn't be able to survive which is why many magicians can survive being thrown in buildings or blown up, their mana strengthens their body and heals their injuries at a fast rate.

The unique mana signature of every person results in not only Their hidden abilities but also their aura.  aura's are special glowing energies that surrounded all living things, it takes most magicians years to be able to see them but they allow people to see the emotions a person is feeling and how many people they have killed in cold blood.

Hidden abilities are unique abilities that each person has, some are passive like aria's sixth sense or deans flower readings and others like Nina's hyped up, Olivia's backup dancers, and Leon's radio delay have to be activated by those utilizing them. Most hidden abilities don't cost mana to use as they are not magic and are simply part of the person using them something they Changes when someone becomes a servant. All people have 2 hidden abilities and some rare individuals have 3 and sometimes even 4.

The flow of mana through the body is what allows people to do all these great things however that flow can be stopped. If a person is seriously cut and bleeding heavily (and isn't a blood mage) their mana may start slowing leaking out into the world around them. Anti-magic magic will also stop the flow of mana as well as disable spirtons, rendering both sides unable to use any other kind of spell. Anti-magic spells also deserve their own chapter but more on that later.

Mana is an essential part of any magicians battle strategy and is a resource that should be carefully managed. I hope this lesson on magic has helped you other magicians out tune in next time for a lesson on spiritons
