Beldia

The first face the Devil King's high command shows in KonoSuba rides a headless horse. Beldia is a Dullahan, an undead knight clad in dark grey armor who carries his head rather than wearing it, and he holds one of the eight seats among the Devil King's Generals. He establishes himself in an abandoned castle within reach of Axel, an odd posting for a commander of his rank, since the beginner town is exactly the kind of weakling territory his pride tells him to ignore. That pride shapes his soldiering: he inspires fear as a matter of policy, follows the army's tradition of sending minions in first, and joins battle personally only when his undead knights fail him. Somewhere under the menace survives a knight's sense of honor, with a soft spot for selfless acts and for animals.
