RageRevan
A world where humanity and supernatural are united and well known throughout the whole world. A world where Gods walk among humans and are not feared, nor treated with too much adoration. A world where Supernatural does not desire to hide their true selves from the world. This world has achieved true unity where humans and supernatural live amongst one another as equals.
Many Supernatural beings have integrated themselves into human lives without hiding their identity and have settled down into human jobs. They don't act like spies or enemies for humanity and just live regular lives. Magic has been incorporated in Technology forming powerful weaponry known as Magitech which can be composed into the military and other locations. However, Supernatural being have their own territorial conflicts and aggressions that is the reason why the alliance is there in this timeline, along with it being announced to the human worlds as well.
Our protagonist Issei Hyoudou, the CEO of the Hyoudou Intelligence will navigate the world ensuring that both sides remain peaceful and happy with one another. While another organisation known as A.I.M.S targets the more rogue Supernatural beings still trying to ensure the status quo of the old Supernatural over humanity is revived.
