Aquilonis, a world located in the lowest realm of Elysium, inhabits the race of Nephilims, beings that are born from Angels and other races.
As for the Aquilonis, the floating islands were inhabited by Sky Angels and Primal Angels, Nephilims that are born to Angel and Bird-type monsters, and Angel and Land-type monsters respectively.
On the other hand, the entire ocean down below is claimed by the Aqua Angels, Nephilims that were born to Angel and Marine-type monsters.
Upon temporarily fusing with the sword of radiance, Azzy transformed into an Angel, grew up with six pairs of white feathery wings, a floating halo above his head, glowing eyes, and carried his plasma scythe.
In his angelic form, he flew above the floating islands, searching for an abundance of life, like a big town or a city. He ignored the small villages on the way, considering they wouldn't be of any use to him for his mission.
