Two of Nightmare’s songs, “TABOO” (unreleased yet) and “Dorastika” (from their upcoming album “TO BE OR NOT TO BE”) will be the intro and ending theme songs to “Doreiku.”
Dorei-ku Boku to 23 Nin no Dorei” is based off of a manga by Okada Shinichi that talks about enslaving people at a price who wear a mouthpiece called an SCM (Slave Control Method). In order for someone to become your slave, you must win over the other person to show your dominance through a duel. The duel can of any kind and can range from simple to complicated. The mouthpiece will vibrate if the wearer is in the vicinity of another SCM user, giving you the choice to duel or not.
RUKA and Sakito have both made a comment in regards to each respective song on BARKS+plus. Below is the translation and is subject to error.
This time, we have received the honor to write the theme song to “Dorei-ku Boku to 23 Nin no Dorei.” People submit to the idea of a TABOO of raising someone, being raised, the changes that occur along with the unchanging things. I wrote the lyrics to tie-in with the theme of “TABOO.” I would be very happy if you can shift your attention to the song lyrics in the movie.
The ending song “Dorasitka” introduces the personality of two people. I wrote this song to express the feelings of Eiya Yuuya’s character in my mind. Of course, there will be a difference between the movie and its original work, but people change as they are being captured. I would also be happy if you can enjoy the song as much as the movie.
There has been no announcements so far in regards to “TABOO” being released as a single from the band.
“Doreiku” will be out on June 28th. Nightmare’s upcoming album will be released on March 19th.
