the Norse God of Light but also has the potential to be the Norse God of Destruction. he is shown to be very possessive as well, disliking it whenever Yui spends time with or gives affection to someone who's not him. He gets annoyed and hurt whenever Yui doesn't understand his advances, also becoming extremely (almost insanely) jealous whenever he believes that Yui might love someone else (namely Loki). He declares that he won't allow anyone else to have her, almost attacking her at one point.
