Gele

A former sage in her previous human days. Her wisdom caught the jealousy of many others, and she was persecuted because of that.

The previous Demon King Nighcisa came upon her battered and tortured body by chance and chose her as the next Demon King. Warped by her bitter past experiences, Gele became the cruelest Demon King known to mankind.

Unlike the previous Demon King, Gele did not actively kill a huge number of humans. Rather, she chose to place them under slavery and the harshest living conditions. Doing otherwise, would only empower the chosen Hero to a level of strength that would be a threat to her.
