Eight Wings of Destruction: The World Trembles at My Summon(DUBBED)

Harry Jobson wakes up in a realm built around beast summoning, where he hopes to find his footing. He calls forth a top-tier succubus, but she quickly abandons him to serve a wealthy man with deeper pockets. Harry, meanwhile, holds a secret system that most people around him know nothing about. When he activates it, the summon that answers is a Fallen Angel, and the crowd responds with open ridicule. Then the Eight-Winged Angel arrives on Earth, and the whole world begins to tremble.
