Work (Millennium Parade and Ringo Sheena song)

The song first aired on February 26, 2023. It was later released digitally on April 1 and was later released physically on May 17, alongside "2045" as a double A-side single. "Work" is the opening song for the Hell's Paradise: Jigokuraku anime,^[1][2] performed as a duet by Millennium Parade, the musical project of Daiki Tsuneta,^[3][4] and Ringo Sheena.^[5][6] It serves as the first collaboration between the two.^[1]

The song's TV version spans for a duration of one minute and 30 seconds, whereas the full version lasts for three minutes and 21 seconds. "Work" reflects on the struggles and contradictions of life and work, criticizing the mundane routine of society while urging listeners to break free, explore themselves, and confront both personal flaws and societal norms. It blends introspection with commentary on modern labor, conformity, and existential questions, challenging the idea of a “correct” path in life and celebrating individuality and survival through adversity. In the music video, the opening visuals of the song for Hell’s Paradise juxtapose intense motion and stark imagery of characters fighting for survival, symbolizing the constant struggle between life and death, a central theme of the series. Characters shown in combat, movement, and transformation visually mirror the song’s existential lyrics about testing oneself and confronting life’s challenges. These visuals reinforce the anime’s story—death‑row convicts fighting monstrous threats to obtain the elixir of life.

The music video for "Work" was directed by Yuichi Kodama with the help of Ryuken Sato and Naoki Kaneko, and was produced by Mamoru Inagaki with Mizuki Ohno. The video features both singers in the city, later panning to them on a stage.
