Collaboration: Nightmare

Nightmare is an influential "visual kei" (refers to a movement among Japanese musicians that is characterized by the use of eccentric, sometimes flamboyant looks) band from Japan. They enjoyed mainstream success with the inclusion of "The World" in the anime series Death Note and are considered a major influence in the ongoing visual kei scene.

Aside from appearing on TV shows, magazine covers, and concerts, they also have a radio program with NACK 5 called "Jack in the Box!". Yomi and Hitsugi usually host the show. However, Sakito, Ni~ya, and Ruka do pop in from time to time with the two. They also have another radio show on CBC Radio called "Hyper Nightmare," where they feature tongue twisters sent in by listeners, adult stories that can be sent in anonymously, and phone-in sessions with listeners who can make interesting sound effects.
