Odin

Odin (オーディン)

The leader of the gods in Norse mythology. He came to Issei's town in order to stop Lokui from creating Ragnarok.

Despite being a god, Odin is a pervert who is constantly stop by Rossweisse, a Valkyrie that was his bodyguard. After the fight against Loki, he leaves Rossweisse in Issei's town (in reality, he just wanted to escape from her so that he can do ecchi things).
