Frey is Freyja's older brother. He was brought to Earth to aid Heimdall in the destruction of Loki, but quickly drops that mission to search for Freyja once he realizes she is there, too. Somewhere along the line, he decides to get Loki's attention by becoming a master jewel thief; the natural enemy of any great detective. Impulsive and quixotic, Frey seems to think of everything in terms of Romantic cliché, dramatic stereotypes, and absurd non sequiturs. His primary agenda is to find Freyja, or at least ensure that Loki isn't corrupting her. However, in the course of his plans, Frey runs into Mayura, falls in love at first sight, and renames her Yamato Nadeshiko (大和撫子, a name for the prototypical ideal woman; a sort of Japanese Dulcinea), and in the English anime, his "Classic Japanese Beauty."
