Loki is the evil God from Norse Mythology, serving as an antagonist within Highschool DxD. He is arrogant as well as overconfident due to being a God. He desires nothing more than Odin's death, which will effectively start Ragnarok (The apocalyptic battle that will cause the world to perish and begin anew). He also enjoys fighting. Currently, his location is unknown, though he was placed under many layers of sealing by Rossweisse.
