The release of the single was announced on July 20, 2025, during the Niigata performance of the group's concert tour Naniwa Danshi LIVE TOUR 2025 "Bon Bon Voyage".[4]
"Asymmetry" serves as the theme song for the TV Asahi drama Revenge Spy, starring group member Kazuya Ohashi.[5] The song is a mysterious and thrilling dance number that reflects the drama's central theme of duality, portraying a story of "unrequited love" within its narrative.[5] A long version of the track was first unveiled during the broadcast of the drama's first episode on July 2, 2025.[6]
"Black Nightmare" is the theme song for the Kansai TV and FOD drama Laundering, starring Joichiro Fujiwara.[7] The track was written specifically for the series and features an addictive electro dance sound with elements of hip hop and rap.
