"Z Densetsu (Owarinaki Kakumei)" (Z伝説 ～終わりなき革命～, "Z Legend: Neverending Revolution"[1]) is the 4th single by the Japanese female idol group Momoiro Clover Z, released in Japan on July 6, 2011.

(the color of Akari Hayami who left the group in April), the girls freeze in shock and the song stops for a split second.

The music video was released on the DVD that came with the limited edition A of the album Battle and Romance that came out three weeks later, on July 27.

[7] In the video, the girls use transformation belts to become helmeted fighters looking like sentai warriors,[7] and the Weekend Heroines[a] squadron fights fully armed with a song and a dance.

[9] The protagonists seem to be ordinary people, but they transform from their civilian selves into their superhero selves at the push of a button, sometimes simultaneously saying a particular word or phrase.

[7] To promote the release of both 4th and 5th singles, Momoiro Clover Z held a series of live events and appearances, one of the notable ones being a concert on July 9, 2012 at the theme park Mega Web 1F in front of the audience of 1,800 people.

At the event, Momoiro Clover performed in the costumes used in the music video for "Z Densetsu (Owarinaki Kakumei)".
