Soul Extinction is a Darkness Magic Spell.
The spell starts out as a transparent sphere with its energy gathered from the surrounding area. Its true form is a large, powerful blast of energy as Freed Justine's Dark Écriture: Darkness and Dark Écriture: Wings spells were no longer active after he was struck by this attack, further hinting to its power. In the manga, the spell is unnamed, but it received a name in the anime.
