The 6 Project

Spirit Magic, Element Magic, Black Magic, Equip Magic, Mage Magic, and Unknown Magic. The 6 kinds of magic that are used in the apocalyptic world. The strongest of all is Unknown Magic, it grants the user magic unique to any other Magician known. Unknown Magic is when the user has overcome all 5 stages of the Sky Virus, also known as Stage 00.
The Sky Virus was created as an experiment in attempt to improve the capabilities of humanity. Everything went wrong since the second the first “victim” was injected. They went crazy, the virus spread, and then more people fell victim to the deadly virus.
It’s been 5 years since the virus has outbroken. And in order to save the world from its complete destruction, 5 mages have created a prophecy. 6 Magicians of different magic will come together to cleanse this world of this virus and create a new world, in where the strongest one of them will become the ruler.
I’m a Magician, I’ve survived the virus with the help of my brother. He won’t tell me what stage I passed though. My name is Asano Ichigo and I’m going to become the strongest and create a new world for me and my brother.

Even if it means getting infected again in the progress.
