Union Magic: Demon-Dweller Sword: Protecting Light 「合体魔法『宿魔の剣・護光』 Gattai Mahō "Shukuma no Tsurugi Gokō"」 is a sword and light-based Union Magic spell.


Using the Demon-Dweller Sword's ability to connect to their allies, the two mages grab hold of the sword, and the Sword Magic user channels the Light Magic user's power through the sword to their allies. The Light Magic creates a large protective aura[1] that also boosts the recipients' speed.[2]
