SEKAI NO OWARI released their new song "Supermarket" on September 18, along with its music video on YouTube.

"Supermarket" will serve as the main theme for the upcoming drama Merry Berry Love, premiering October 7 on Nippon TV and Disney+. The lyrics were written by Fukase, while Fukase, Saori, and Nakajin composed the song together. The track features a light melody accompanied by a jazzy, rhythmic sound.

Directed by London-based filmmaker Taichi Kimura, the music video takes the form of a suspenseful thriller inspired by Hollywood horror films. It shows Fukase being attacked in an office, Nakajin sinking into a swimming pool, DJ LOVE running through a field, and Saori playing the piano. The video builds toward an unexpected conclusion in its final moments.
