Dark Art

'Dark Art' (闇術(あんじゅつ), Anjutsu) is the generic name of magic and the users of Dark Arts are known as «Kuroma» (黒魔, くろま, lit. Black Magic).

Principles

Saviors who are able to use Black Magic has mana, the power source required to cast Dark Arts. In the midst of casting a spell, a Kuroma absorbs the natural powers from their surroundings to increase their mana to cast the chosen spell; then the spell is then written in midair before the caster. All Dark Arts are split into different groups and strengths based on the number of lines that the spell in question as such as the "Step One Dark Arts: White Breath" has one line and "Step Three Dark Arts: Frozen Shade" has three lines.

There are two individuals who're able to use powerful Dark Magics and incantations, which has enough power to be able to cause enough destruction to force maps to be redrawn referred to as "Grimoire Holders". Two of these spells are Step Thirteen Dark Arts: Celestial Crusaders and Ouroboros

Dark Arts can also be used to enchant their or someone else's weapon as shown in the anime as Shizuno used "Freezing Shade" to enchant Satsuki's Arciel to release a freezing slash.
