Demon-Dweller Sword: Conquering Eon

Sword Ultimate Magic: Demon-Dweller Sword: Conquering Eon (剣究極魔法『宿魔の剣 覇劫』) is Licht's sword-based Ultimate Magic spell.

Description
Licht holds the Demon-Dweller Sword aloft and has it absorb the magic of their allies. He then swings the sword down and unleashes the collected power in a single slash.

The resulting attack is powerful enough to disintegrate a high-ranking devil as powerful as Zagred, leaving behind his heart, before healing himself, as well as annihilate a section of the Shadow Palace.
