Delsgade

Demon King Castle Delzogade (魔王城デルゾゲード, Maō-jō Deruzogēdo) was Anos' castle 2,000 years ago. It is now used as the Demon King Academy.

History
2,000 years ago, Anos killed the God of Destruction Aberneyu and turned her into the Demon King Castle Delzogade.

Description
Delzogade is a three-dimensional magic formation, so even after 2,000 years it haven't changed much. Anos can only use Venuzdonoa while in the vicinity of the castle. Despite being repurposed into a school, Anos can summon his castle through magic.
