Magia Erebea (
Magia Erebea is a forbidden technique created by Evangeline A.K. McDowell over a period of 10 years, in which the user absorbs offensive magic designed to harm the enemy into his own body, to the point where it fuses with their very soul. The technique feeds on the user's body and soul, but in return the user gains power many times that of any ordinary person. There are only four known users of Magia Erebea, Evangeline A.K. McDowell, who created the technique but uses an incomplete form, Jack Rakan, who learned the technique but was never able to use it properly, Negi Springfield, Eva's disciple, the first to ever use the technique in a complete form, and Negi's grandson/clone, Touta Konoe, whose level of mastery appears also to be complete after learning his 'revolution' technique in which he circulates Magia Erebea and the White of Mars. 
When Touta first uses this ability, his arms become covered with something resembling pieces of black armor. Nagumo notes that it reeks of powerful and evil miasma. Similar to Evangeline and Negi Springfield's versions, this ability greatly enhances Touta's physical capabilities. When first using it, Touta is able to out-manuever Kaito, and knock the werewolf several meters away with a single punch.
When the user absorbs a spell using Magia Erebea they gain that spell it's properties, enhancing their physical and mental abilities, this is known as Armament. An example of this is when Touta catches a lightning spear and is able to use his Grandfather's technique: "Raiten Taiso"
- Raiten Taiso - used by Negi Springfield and Touta Konoe, it allows them to move and think at the speed of lightning
- Krystalline Basilea - used by Evangeline A.K. McDowell, creates an ice-sphere that gives her complete control over the area.
The primary disadvantage of the Magia Erebea, however, is the corruptive nature of the spell. It feeds on the users body and soul, as any dark feelings; such as hatred, greed, lust, revenge, in other words, negative emotions. As the corruption furthers, the user's body is overwhelmed by their own darkness and negativity, transforming their body in a partially reptilian monster; granting them a clawed hands and feet, a long, whiplike tail, as well as more prominent canines and longer hair. When in this monstrous state, the user gains vastly enhanced physical abilities and magical power, which is evident in the crest-like aura the emanates from their body, but lose all sense of self, becoming a monster with no sanity bent entirely on killing everything in their path.
