There are the 4 races; Humans, Elves, Dwarves and Dragons. All of these races are at peace with each other, meaning no wars not conflicts.
Though there is peace, there are those who believe that peace is too over rated. This group of people are the Villains, A hierarchy of evil doers.
To stop the Villains, there are those called the "Swords". Their job is to capture and reform. There are 100 swords for each race, and for each race of Swords there is a seperate Hierarchy. Like most Hierarchy's, the lower the number, the more repeat and privileges you earn through out your missions.
The is a small clan of an Ancient Race that is secluded from the rest of the world; Jiu Mountain, and Jiu Village at the peak. The Village is full of Angels and Demons, yet there is no in between.
Every 10 000 years, a special enhanced Race is born, the Arch Angels and Arch Demons. In no part of history is both born, it's just a gamble on who births it and what it is. It's strange because 2 Angels can give birth to a Arch Demon, and 2 Demons can give birth to an Arch Angel.
But in the year 23007, the strangest phenomenon occurred; 2 Angels gave birth to an Arch Demon, AND 2 Demons gave birth to an Arch Angel, in the SAME year at the SAME time. Once they were born, the children were gifted masks of their own; The Angel, a Mask that had Lotus Flower imprints. The Demon, a mask that had falling Rose petals imprinted. If you wanted to tell what the difference between an Arch and a Norm; Norms usually have 2 or no wings, and Archs usually have 4 or 6 wings, 6 winged Archs are usually incredibly rare, and 2 6 winged Archs were born at the same time.
After both children were born, the families grew closer, since they found that if the 2 Archs were able to become friends they'd face anything together. The 2 Archs grew to age 5, where they were like brothers. They usually got bullied by some food the kids around their age, but they weren't affected because they had each other for comfort.
Once they reached age 10, a huge incident occurred, changing every bodies lives.
