Beldia (ベルディア) was a Dullahan, a former knight, and one of the Demon King's Generals.


Beldia is a headless undead knight clad in dark grey armor who rides a headless horse.


He still retains some chivalrous and honorable aspects of his former life. He is somewhat of a closet pervert, but is too proud to admit it in public.

While in the show only his detractors are shown for the most part, it's later revealed that he is also hardworking and dedicated; after moving into his base of operations near Axel he would work alongside his grunts repairing the various damages to it caused by Megumin's explosions, showing a tolerance for it at first (dismissing it as nothing but a "test of courage"), but eventually reaching a breaking point and assaulting the town, something he had not planned originally.


Beldia was once a honorable knight that was unjustly executed. Afterward, his grudge over this matter transformed him into a Dullahan. Later on at some unknown point in time, he joined the Demon King’s army (indirectly reason Wiz became a lich, due to cursing the latter's companions). The Demon King later sent him to Axel to investigate a mysterious light that had suddenly appeared, which was likely caused by Aqua's appearance in their world.


Premonition of Death: A deadly curse that will kill its target within a week. It is extremely potent, seemingly only curable by those with divine powers.
