Bezel

A middle-aged man with an air of intelligence about him, Bezel was the one who told Tsuguhiko he was the Demon King, and encouraged his revival. He was also the right-hand man of the former Demon King.

Bezel concluded that Aidam, who had been thwarted by the valkyries each time he returned, was not fit for the title of Demon King, and so launched a plot to steal Tsuguhiko’s power for himself.
