The Demon Legion

Each Great Demon was over ten meters in height with gigantic wings on its back. There were long, curved horns on the top of their heads and they looked ferocious. They were emitting terrifying dark auras. 

They managed to stabilize the light doors. More demonic creatures charged out of the doors. The Little Demons had bright white bodies whose statures were shorter surging out in succession. One should not look down on them since they were the casters of the demon world. They were skilled in mobilizing dark power and cast all sorts of negative magic spells.
