History
The evil God of Norse, Loki married the Giantess Angrboða and gave birth to two sons: Fenrir and Midgardsormr.

Plot
Loki appears in Volume 7, intending to murder Odin and create Ragnarok. In his initial battle against the Occult Research Club, he was able to overwhelm them with his son, Fenrir, but decided to retreat after seeing the Vali Team, claiming that it is enough to see the Two Heavenly Dragons together. In the final battle against both the Gremory and Vali Teams, Loki summons Fenrir's sons, Sköll and Hati Hróðvitnisson, and many Midgardsormr knockouts to attack them which was easily disposed of. Loki was defeated after Issei gains access to the imitation Mjölnir (courtesy of the Breast Fairy), adding with the Holy Lightning of Baraqiel and Akeno and allowing them to defeat Loki. After his defeat at the end of Volume 7, he was placed under many layers of sealing by Rossweisse.

Powers & Abilities
Being a God, as well as an expert of Norse magic, Loki is extremely powerful. He was able to take on the Occult Research Club members, Azazel and Baraqiel at the same time with ease, indicating power beyond that of an Ultimate-Class Devil.

He also has a high endurance to damage, as shown when he took the full blow from Durandal without being injured. He was also able to take Issei's attack that has been boosted several times with only his hand slighty burned.
