Nightmare - Raison d'être

Nightmare is a visual kei rock band from Sendai, Japan. They enjoyed mainstream success with the inclusion of "The World" and "Alumina" in the anime series Death Note and are considered a major act in the ongoing visual kei scene.

Nightmare's band concept is Gianizm and this word occurs in many of their song titles. Gianizm is derived from Doraemon's character Gian. Gian's motto is "Omae no mono wa ore no mono. Ore no mono wa ore no mono." ("What's yours is mine, what's mine is mine.") Incidentally, this is also the name of the two 'best of' albums they had re-released their indies' songs on. However, the band has often ventured into new genres or styles, such as in "Naked Love" where they experiment with electronica, or "Masquerade and Konoha" where they experiment with ska and reggae.
